==Correction to "obtaining the blood"==
"A large[51] needle (16 to 17 gauge) is used to minimize shearing forces that may physically damage red blood cells as they flow through the needle.[52] "
This is commonly believed by phlebotomist, but not empirically supported. Many people call it an old wives tale. Smaller gauge needles do not increase hemolysis except when vacuum containers are used and they are only used in blood donation to draw samples for testing. Large bore needles are used because they have higher flow rates and allow the donation to be completed in less time, and the higher flow rate also prevents clotting. I just need better sources to fully support this.

==Global view==
The "needs globalization" tag was added with no discussion, just a comment that the page is "US-centric."  That's hardly a prima facie case, especially since at a glance I see Australia popping up.  It would certainly strenghten the argument if the globalization-happy person who made the change had cited some detail where other countries do substantially different things from the article.  
([[User:Hyperionred|Hyperionred]] 18:57, 6 September 2007 (UTC))

I have added a globalisation tag again.  This is an appalling article.  Adding in "other countries do this" is NOT a worldwide view.  Nearly every single reference is an American one.  The article uses blood donation information from the USA as fact.  I believe the tag should stay until this mess is sorted out.  This article should be scrubbed clean with generic information and sub-headings of the countries, or if required new articles such as [[Blood donation in the United States]] with appopriate summarising in this article.

:There are probably some specifics that vary about the process, but I'd be extremely surprised if the process is all that different in Europe.  Most of the practices described are things that would be done worldwide, though resource constraints probably limit the testing in some areas and high risk donors would be identified differently.  I'd agree that it needs a globalization tag, but "appalling article" is probably a little severe.  Compare (http://www.ibts.ie/generic.cfm?mID=2&sID=11&ssID=2), which is an irish site to the article.
:http://www.scotblood.co.uk/docs/dsr_m_2006.pdf is the donor questionnaire, and there are some differences in the eligibility criteria, but nothing shocking (I'm a little surprised that they consider the Americas as the only high risk region for Malaria, but the number of cases of confirmed transfusion transmitted malaria is painfully small to begin with).[[User:Somedumbyankee|Somedumbyankee]] ([[User talk:Somedumbyankee|talk]]) 18:40, 30 December 2007 (UTC)

==Iron test==
What's this? ''by a simple [[iron]] test. A [[phlebotomist]] pricks the donor's finger and elicits a small drop of blood.  This blood is placed into a chemical solution &mdash; if the blood is [[density|dense]] enough to sink in the solution, there is sufficient iron in the blood to donate.'' I have never seen this or heard of it. Standard procedure is probably a hemoglobin quickcheck with a hemoglobin photometer. [[User:Kosebamse|Kosebamse]] 19:45, 10 Apr 2004 (UTC)

:They did it to me.  I can't say for sure if the person who pricked my finger was a phlebotomist (I have no idea what it means), or if they were really testing my iron levels, but it appears as though the finger-prick-sink-or-float is one standard way of doing it.  I know for sure that different places bandage you differently after the donation, so they aren't absolutely uniform. [[User:Paullusmagnus|Paullusmagnus]] 22:56, 11 Apr 2004 (UTC)

::Phlebotomist is a person who is licensed to draw blood.  I should start a page on that.  I know they do the donation process, but not sure if they do the iron test.  

::Not sure what a "hemoglobin quickcheck" and "hemoglobin photometer" are.  The process described here is how it was done for me the three times I've donated blood (Western [[NY]], and [[Massachusetts]]).  It seems very likely to me that different methods are used in different regions of the world, or with different administering agencies.  Unfortunately neither the [http://www.givelife2.org/donor/process.asp Red Cross page] nor [http://www.blood.co.uk/pages/step3.html Britain's National Blood Service] give further details, only saying that "iron content will be checked," so we can't reference it well.  Kosebamse, perhaps you can add information about the iron test you're more familiar with?

==Sexual orientation and blood donation==
Is this a good place to mention that homosexuals (males who have had sex with other males since 1977) as well as anyone who has been to Africa or had sex with someone who has been to Africa are prohibited from ever giving blood?
[[User:Ickle|Ickle]] 10:19, 23 Sept 2005
:Watch your US-centricism.  Obviously people who have been to Africa can donate blood in Africa, for instance, and the USA is the only place I know that has an outright ban on blood donation from any man who has had sexual contact with another man. [[User:NTK|NTK]] 20:13, 17 December 2005 (UTC)
:The ban for gay men applies in the UK too. You are tested and may be asked to come back if you've been in a malarial country with in the last 6 months or if you've been in the USA (yes, believe it!) in the last 28 days due to a mosquito that is around during the summer and autumn months. [[User:DavidBoden|DavidBoden]] 21:36, 11 January 2006 (UTC)
:Incidentally, the public policy justification for these bans is very weak.  For instance, the "sexual contact, even once" standard for man-on-man relations excludes even someone who had one gay blowjob with a condom in 1978 and has been tested for AIDS many times, whereas if you had unprotected sex with a prostitute 13 months ago that's fine.  Or if you've had unprotected sex with an unlimited number of women of unknown status at any time.  The ban on people who have lived in Africa or even had sex with someone who lived in Africa is equally indiscriminate.  And it can't be justified on the grounds of simplicity, because the donation questionaires have almost 100 questions, and are extremely detailed.  [[User:NTK|NTK]] 20:18, 17 December 2005 (UTC)
::''The MSM (Men who have sex with men) deferral isn't based on the activity so much as the community.  It's a community that is at high risk, which has been shown repeatedly by studies by groups like the CDC.  The reality is that it is discriminatory, but it's felt to be justified because the risk among MSM is so much higher.  The rules are designed to protect recipients from harm, not donors from being offended.  Ironically, MSM are probably the most likely to know they have the disease since testing is more common there than in the population as a whole, and the high rate there may simply be a sampling bias based on who's been tested.  Notably, the deferral for tissue donors, which is issued by the same Center within FDA, is only 5 years for MSM.  The highest risk heterosexual contact is covered by the "money or drugs for sex" questions.  <small>—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/150.148.0.27|150.148.0.27]] ([[User talk:150.148.0.27|talk]]) 01:10, 7 December 2007 (UTC)</small><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->
::''Obviously people who have been to Africa can donate blood in Africa, for instance, and the USA is the only place I know that has an outright ban on blood donation from any man who has had sexual contact with another man.'' Well, just to put a bit of perspective on it, in Norway, neither men who have or have had sexual contact with other men nor women who have had or have sexual contact with men in that category can give blood.

== Donation time length ==

How long does it typically take for 500 ml to be donated? --[[User:Commander Keane|Commander Keane]] 13:02, 14 July 2005 (UTC)

:4-15 minutes is the standard most blood banks use as a "normal" donation.  Too fast probably means you hit an artery and not a vein (messy and painful), and too slow leaves a risk of the blood clotting in the tubing and other problems.  6-8 minutes is typical.  Most of the time in donation is in health screening (10-15 minutes), setup (5-10 minutes), and just good old fashioned waiting your turn, especially if you didn't set up an appointment (0-? minutes).

:20-30 minutes. [[User:Jfdwolff|JFW]]&nbsp;|&nbsp;[[User_talk:Jfdwolff|<small>T@lk</small>]] 14:24, 14 July 2005 (UTC)

: I think it is less than that; it typically takes me 12-15 minutes to give blood (once I have been "plugged" to the pump). I'll check that next time I give blood. By the way I live in Quebec... but I guess the technology used here will be similar to yours. -- [[User:Hugo Dufort|Hugo Dufort]] 22:12, 27 November 2006 (UTC)

:That depends on the indivdual. In some (rare) cases it may be infinite (e.g. the chosen blood vein collapses prior to reaching 500 ml as the body has rerouted the return blood flow to a nearby vein. That happened to me three times. [My brother is worse, when they needed the much smaller amount of blood for testing they had to poke him repeatly to get enough blood.) The blood banks themselves tend to start the last treatments no later than 30 minutes prior to planned closure. [[User:Joncnunn|Jon]] 19:48, 21 June 2007 (UTC)

== Invigoration/Benefits ==

"Anecdotally, elderly people in good health have reported feeling invigorated by giving blood on a regular basis."

''Burns 650 calories'' may well be true but is hardly a benefit as donors need to eat extra to make up for the lost calories and in my view is an unhelpful way of looking at donation.--[[User:JBellis|JBellis]] 11:32, 3 January 2006 (UTC)

::: I usually feel very tired, sometimes depressed after giving blood. It lasts 1-2 days. I think the feeling you get after donation is very subjective and may also depend on many factors (what you eat, physical activity, etc). In Quebec, you have to wait 56 days before giving blood again. Hopefully! [[User:Hugo Dufort|Hugo Dufort]] 22:15, 27 November 2006 (UTC)

I disagree, and believe the caloric debt should be corrected and restored. First for the correction: if the pint of blood is equivalenced to a literal pound of flesh, that is worth at least 1000 Kcalories based on the equivalent amount of grilled marbled steak. But even that is an underestimate. The most efficient feed-lot animals (chicken or farmed fish) convert feed into flesh with less than 3o% caloric efficiency (just imagine the elaborate biochemistry involved in breaking down foodstuffs and resynthesizing more of yourself.) Thus the caloric debt is plausibly in excess of 3500 Kcal, the very amount which must be lost to shed a pound of weight. Sure the Red Cross gives you a donut or two, but few people treat themselves to the equivalent of a glutton's feast after a blood donation. The relevance of all this in my opinion is that donation at the maximum rate of 6X per year can easily offset the couple of pound upward drift that is common in middle age and beyond. To be sure, so could leaches!

:I don't think that you can directly compare blood and muscle as blood clearly has a much higher proportion of water.--[[User:JBellis|JBellis]] 19:43, 26 March 2006 (UTC)

:: Blood is a good deal thicker than water! The packed red cell volume in males is 55% and the remaining plasma is 20% protein. By comparison, raw meat has 70% water by volume. I still hold that a pint of blood is a pound of flesh!

::: Blood is thicker than water.  Whole blood has a density around 6% higher than water, though, so it's not *that* much.

:::Where does that 55% figure come from? The article on [[hematocrit]] indicates typical values of 42-52%, and in my (admittedly scanty) experience it's usually towards the low end of that range. And given that those red blood cells still contain a fair volume of water themselves... --[[User:Calair|Calair]] 01:02, 27 March 2006 (UTC)

:::55% is unusually high for a crit, and probably indicates either dehydration, some sort of iron overload, or just high altitude living.  Too high of a crit makes the blood too thick to get around the body efficiently.

:I'm new to contributing to Wikipedia and won't try to reinsert the line I wrote about calories burned from donating blood without support from others.  However, I searched blood donating on Wikipedia specifically for this information and I do think it is a helpful fact to know.  While it is true that blood donated must be replenished by eating more, those whose bodies are less sensitive to blood donation may be able to consume additional nutrients more slowly than others, thereby achieving some minor weight loss advantage.  More importantly, people on strict diets who count calories and still want to donate blood would find such information useful to know how much they should supplement their diets to compensate for nutrients lost during donation.  Am I the only one with this opinion?  JBellis, I'd appreciate your response.--[[User:Gimeral|Gimeral]] 21:26, 3 January 2006 (UTC)

::I didn't delete your line from the article and I'm not a nutritionist so I couldn't really attempt to answer your question.  I believe that it is medical advice to eat soon after doning. --[[User:JBellis|JBellis]] 22:28, 3 January 2006 (UTC)

:: Please re-add this figure if you've got good reason to believe it's in the right ballpark. I just got back from giving blood and I was interested how many pizza slices I can eat to balance my ying and yang :) [[User:DavidBoden|DavidBoden]] 21:35, 11 January 2006 (UTC)

::The may clinic lists 650 on their blood donation website. http://www.mayoclinic.org/donateblood/know.html, I've seen calculations to justify it elsewhere. DanD

First, donating blood does not "burn" calories. What it does is remove protein, fat and carbohydrate that will be replaced. Second, the replacement of plasma is in a day or two and is almost entirely water, so that's 55% of the pound of blood removed without having to require calories. Third, replacing red blood cells doesn't get started until five days after, and takes 4-8 weeks to complete, so there is no excuse for eating extra after donating. As for actual number of calories being removed, my calculations come to 425 for women and 460 for men (higher because of higher percent of blood is red blood cells). My calculations do not include the additional energy of synthesis of proteins, hemoglobin and cell membranes, so that might be the bridge to the higher estimate posted at the Mayo Clinic website. And yes, I have a doctorate in biochemistry.[[User:David notMD|David notMD]] ([[User talk:David notMD|talk]]) 05:58, 12 February 2016 (UTC)

== Preparation ==

I hear that in some countries (e.g. Italy) the session must happen in the morning and the donor is required not to have eaten anything for 12 hours before the donation, supposedly to get "purer" blood. Is that true? If so, why do other countries not do that? Thanks. [[User:PizzaMargherita|PizzaMargherita]] 23:52, 12 February 2006 (UTC)

: The reason why some blood banks may want to avoid overfed donors is that too much fatty food actually starts showing up in the plasma.  Heavily lipemic plasma looks a lot like an orange smoothie, and since the tests (i.e. the anti-HIV EIA) on the blood are read by an optical device, they can't test it.  The tradeoff is that hungry donors are more likely to faint, fall, or otherwise have problems.  Most places I've dealt with feel that losing a unit or two is better than losing a donor (many studies and common sense point out that a donor who has a reaction is very unlikely to return), so they encourage donors to eat.

: You're not thinking of blood ''tests'' maybe? Things like blood-sugar testing often require fasting before a sample's taken, but I've never heard of it in connection with donation before. --[[User:Calair|Calair]] 00:18, 13 February 2006 (UTC)

Ok, I found a [http://www.avis.it/usr_view.php?ID=1571 reference]

:''Bisogna essere a digiuno per donare sangue?''
:''Il mattino del prelievo è preferibile essere a digiuno o aver fatto una colazione leggera a base di frutta fresca o spremute, thè o caffè poco zuccherati, pane non condito o altri carboidrati.''

This roughly translates to
:Q: Do I need to fast before I give blood?
:A: In the morning of the drawing it's preferable to have fasted or have had a light breakfast based on dried fruit or fruit juice, tea or coffee with little sugar, bread with no dressing or other carbohydrates.

In other countries I'm pretty sure they suggest to eat something before you give blood. [[User:PizzaMargherita|PizzaMargherita]] 00:51, 13 February 2006 (UTC)

: Yes, Australian Red Cross certainly does[http://www.giveblood.redcross.org.au/Donor/guide/what-happens.asp]: "Please ensure that you drink plenty of fluids (at least four glasses) in the hours leading up to your donation and that you eat something healthy and substantial beforehand." American Red Cross[http://www.givelife2.org/donor/tips.asp] encourages donors to "Have a good breakfast or lunch", but also to avoid fatty foods because they can interfere with screening for diseases. Doesn't mention carbs, but I wonder if the Italian rules are for similar reasons? If somebody can find out, it might be worth adding to the page. --[[User:Calair|Calair]] 01:47, 13 February 2006 (UTC)
::... yes in the US they do advise one to arrive on a full stomach :) so to avoid fainting afterwards maybe -- the donors are generally supposed to be able to drive themselves home after all! and by the way, they also require not to take any caffeine.

:::"except if they offer real good lunch right after the deal"&mdash;funny you should say that, I was told they actually do...

I think that it's question of balance between getting 'good' blood and taking care of doners.
:::I have donated blood almost every two months in the United States for the past several years, first with the Red Cross and more recently with the NY Blood Center.  They definitely do encourage you to eat before donating; the last time I donated they specifically asked about it during the screening.  I have ''never'' been told to avoid fatty foods and definitely not to avoid caffeine; strange that you mention that, because I have become a coffee addict and definitely had a good bit of caffeine in my system the last time I donated.  In fact in all the literature I have read I have not even found any proscriptions against drinking alcohol beforehand either, obviously they are not going to let someone stumble in drunk and donate, but it seems that even if someone had a drink or two beforehand that is acceptable, given the fact that they ask fifty different questions, including if you have taken aspirin in the past two days, they certainly aren't neglecting to ask about fatty foods, caffeine, or alcohol.

In response to the "<nowiki>{{unreferenced|date=August 2006}}</nowiki>" tag on this section, I took the liberty of rewriting this section. I moved the "check with your local blood bank" sentence to the top of the paragraph to emphasize its importance. I rewrote the description of the requirements a bit, relying specifically on the web sites for several countries' blood banks. If other countries have substantially different requirements from the sources I used, please make the appropriate edits (like you need me to tell you that). I left the "some countries require a fast" sentence in place, even though none of the countries I cited to impose that requirement; I added the "<nowiki>{{citeneeded}}</nowiki>" tag to that sentence. I see that there's a possible cite earlier in this discussion, but I didn't want to add that cite myself since I can't verify the translation.

== Complications ==
I've been trying to find more information about complications and so far the internet has not turned up anything other then bruising.  No time duration for bruising or other symptoms are discussed.  I also have a hard time believing 1% of people get bruises as for me personally it's more like 25% of the time.  Regardless a week ago I gave blood and the last few nights I've been waking up with my arm really hurting.  The bruise is also showing a bit of a direction towards my wrist. A slightly injured shoulder above the arm is really starting to hurt in concert with the arm during the night...  Could laying down cause an increase in the pain compared to standing?  Should I seek medical attention?  Has there been anyone else have these kind of symptoms?

:Some of this may depend on what is defined as "bruising". Myself, I usually wind up with a small bruise right by the needle puncture point, but nothing more. I've once had a more serious one (had to do with an unexperienced nurse who didn't get the position right at first and had to reposition the needle while it was in my arm) and I've known a few people who are generally prone to bruising and have suffered more serious problems. For what it's worth, they mention offhand the "serious issues" due to the needle hitting a nerve. I've had it happen once, causing constant midlevel pain for a few days and weakness of the arm. I had a roommate in college who lost use of his right arm for a day, but that was once in a history of years of donations for him. Ultimately, as with any medical procedure, there's a small chance of severe complications and a decent chance of very minor ones for most people. And there will always be a few people who have serious reactions. Incidentally, psychology has a lot to do with it. The human brain encodes certain fears very broadly so that if you experience them once or twice, you can get scarred for a good amount of time. I don't remember blood donation being one of them, but the symptoms of dizziness are close enough to food poisoning, a known primitive fear, that I could see crossover. -[[User:SeanDuggan|Fuzzy]] ([[User talk:SeanDuggan|talk]]) 15:34, 6 March 2008 (UTC)

===Lightheadedness===

I have donated blood a total of six times.  Around the fourth time I got mildly light headed and needed to lay down.  Now I gave for the 6th time today and I nearly passed out.  I was at the point where my hands and feet felt like they were asleep (pins and needles.)  While recovering one of the phlebotomists(?) mentioned that some people, once they start getting light headed from donating, actually have a higher chance in the future of passing out and will actually experience a worsening of that complication on subsequent donations.  I don’t want to stop donating (as was suggested) so I was looking for information on this.  Does anyone know if this is true, and if so maybe it should be included in this section of the article? I'm looking for any research or information on that now and if I find any I'll post it here. --[[User:Jeremyh113|Jeremyh113]] 19:42, 14 March 2007 (UTC)

:I don't know any reason for this, except that psychologically it could become an expectation.  Unless you were not spacing your donations enough, I think the most important thing is to make sure you are properly hydrated and relaxed in advance.  Having eaten some carbohydrates a while beforehand might help too.  If you want an expert opinion, ask a doctor. [[User:NTK|NTK]] ([[User talk:NTK|talk]]) 09:06, 29 November 2007 (UTC)

Anecdotally, the lightheadedness is often a physiological reaction of the body to some "damage"/needle/blood loss.  Similar to when you are cold the body will try to reroute/conserve blood and cause some loss of blood to the head.  I find that a cold washcloth on the back of my neck is usually more then adequate to keep me from tunnel-vision.-Mike R

Tell the phlebotomist of your concern before you start. The response should be to elevate your feet and put a coldpack behind your neck (Mike R's note). And to stay prone a bit longer than usual before standing up.  Part of the problem is that if you have had a few bad experiences, the anxiety contributes to triggering the lightheadedness.[[User:David notMD|David notMD]] ([[User talk:David notMD|talk]]) 20:30, 16 February 2016 (UTC)

The ARCBS has been the subject of major Australian news stories more than once - e.g. [http://www.smh.com.au/articles/2003/05/14/1052885298025.html a Hep C contamination scandal], and controversy over [http://www.abc.net.au/7.30/stories/s68878.htm what should be done to protect blood recipients from CJD]. (There was a front-page blowup a while back about blood freely donated to the ARCBS ending up in for-product research or products, though it would take me more digging to get good refs for that one.)

:A national blood bank is a significant part of a nation's health system, and has to deal with some fairly controversial issues - while things like Hep C and CJD affect every blood service, each organisation deals with those issues in its own ways, and that tends to provide enough of interest to make them notable.

==Use/discard bar codes?==

When I donated in the USA in 1997, I was given two bar-code stickers and left in privacy to stick the appropriate one on the blood bag (or maybe it was on the paperwork, I don't now recall). The idea was to deal with the danger of at-risk people giving blood just to get a free HIV test - one sticker meant the blood would be tested but not given to patients, the other meant it was OK to use (pending the usual testing). Anybody more familiar with the US donation process feel like mentioning this in the article? --[[User:Calair|Calair]] 03:24, 4 April 2006 (UTC)

: Part of the problem here is that the US has no one standard set of blood procedures. The American Red Cross is a nationwide provider with standardized procedures, so that's a good reference point, but there are regional blood centers where different procedures are used. For example, at the center where I currently donate, patients are not given barcodes in this way. Instead, they are given a phone number that they can call after the donation if the blood should not be used (and several questions asked during the screening procedure emphasize that blood donation is not an appropriate way to get an HIV test). [[User:KickahaOta|Kickaha Ota]] 16:20, 4 July 2006 (UTC)

I just donated today actually.  Here in Canada, they have this.  After the nurse checks your blood pressure, heart rate, checks your arms for needle marks, asks all the high risk questions etc. etc. they leave the little cubicle and there are two stickers that say "Use my blood" and "Do not use my blood".  It's basically just because they know that there will be people who will use blood donation as a means of having themselves tested for STD's and there's really nothing they can do about it.  This is just because the tests are not 100% accurate and a person will be able to get themselves tested still but they can anonymously have their blood discarded rather than used, they still get tested but hopefully have the sense to keep others away from such a risk.  In Canada all blood donation is handled by Canadian Blood Services, a government organization so everything is standard.

== fainting ==

I just donated blood today and I fainted near the end of operation.  I lost all energy and everything went black, then I remember waking up with doctors struggling to keep me down because I was really tense (it was quite scary)

I noticed the article make no mention of fainting, perhaps that should be added.




Agreed, I fainted today too, and I think it is a part of blood donation and should be included.
Also, my blood was taken with a bloodmobile, maybe those should be mentioned too.

: The 'Complications' section says: "During or shortly after the donation, hypovolemia may occasionally lead to a drop in blood pressure with some donors experiencing light-headedness or fainting." --[[User:Calair|Calair]] 00:30, 23 August 2006 (UTC)

Sure it should be in there.  It isn't overly common in healthy individuals, but the lowered blood sugar levels can cause lightheadedness, dizzyness, fainting etc. etc.  That's what the cookies and sugar juice are for.



We had a blood drive at my school that I decided to take part in. My blood pressure is already fairly low - it's between 90-120 / 50-60 most days. Before I gave blood, it was 118/56. About five minutes into the procedure, I began feeling light-headed and started to see stars, so I decided I'd ask the nurse "About how light-headed should I feel?" just to double-check. She then told me that I shouldn't be at all, so she quickly disconnected the needle, elevated my legs, and laid my head down flat. Then she gave me cool, damp rags for my head and stomach as well as a can of soda. It was somewhat alarming, but it happened to several other people that day - I noticed one of my friends in the same position as I was leaving the donation area, and before I donated I watched as a nurse laid a girl on the floor and put her feet up on a chair, also placing damp towels on her head and stomach. 

So apparently, it's normal.
[[User:Dakana2511|Dakana2511]] 02:05, 11 March 2007 (UTC)

Yeah, I was in charge of organising a blood drive for my school. We took a group of 8 each week and about every two weeks someone would faint. It usually occurs in lighter people as a standardised amount of blood is taken (470mLs in Australia) as long as you weigh 50kg, and as lighter people have less blood, the rapid decline in blood volume results in not enough oxygen carried to the brain - hence the fainting. I fainted during my last donation, and it was so embarassing. I was talking to my friend and aparently I stopped, went tense and pulled a wierd face. I woke up with like 4 nurses around me, looking like i was dying. I felt fine, but it was pretty shocking, not to mention embarassing, to wake up with 4 faces frantically assessing you. I haven't been back since :S But I feel I probably should soon. [[User:Pure motion|Pure motion]] 13:13, 22 October 2007 (UTC)

==Donations vs. Selling==
Should there be something in this article about why blood cannot be sold (but plasma can) in the United States?  (I'd add it if I could remember, but sadly I do not.)  --[[User:Dr Archeville|Dr Archeville]] 14:23, 11 August 2006 (UTC)

I am curious about this topic too.  I donate blood regularly, but often I wonder why I should go through this expense of time and discomfort without compensation on the behalf of someone getting a surgery--maybe even a cosmetic surgery--if the person undergoing the surgery has the ability to compensate me for my efforts.  I am happy to donate blood to the poor who can't afford it, but why the charity for the rich?  I live in the U.S. and most people in this country have more money than I do.  There are clearly no widespread ideas that "blood should be free for everyone," because the blood donation agency and the hospital both charge the patient for my blood. --[[User:Charis1517|L. Bartlett]] 03:39, 9 September 2006 (UTC)

I also think this is an important subject to include (or link to a new article).  IMO the selling of blood has played a role in spreading blood born diseases such as HIV (eg injection drug users selling blood to get a fix).  It was also an impetus in the [[Health_Management_Associates_Scandal]]. --[[User:Mm1972|Mm1972]] 20:12, 9 September 2006 (UTC)

Paying money for blood donations is plain and simple a bad idea.  It's unfortunate, but the bottom line is that when you have a process by which people can make money quickly, easily, and without having to sacrifice anything tangible they're going to miss, it attracts a certain demographic.  Such a program is more likely to attract members of the lower economic group of society.  Statistically, the least well off members of society are far more likely to carry transmitable diseases such as hepatitis, HIV, etc. etc.  It isn't unfair or prejudiced anymore than insurance companies charging higher premiums for younger drivers is.  It's merely a statistical truth.  Plasma donation, at least in Canada whose system I'm familiar with, is a more involved process than blood donation.  Under certain circumstances, those who wish to donate must have a physical examination and are put through more rigorous screening than blood donars are.  

Here in Canada I think this is solid and sale of blood isn't something up for debate.  Due to the private nature of American health care though, I can see it being a different story.  But even still, though the testing methods for blood are extremely accurate, as we know, mistakes can always be made.  The costs of compensation of patients who have been exposed to tainted blood is absolutely enormous in some cases.  So they have to take any possible precaution they can do ensure their sources are safe.  That's why they ask all those ultra personal questions ie. "Have you paid for sex....  Have you had sex with another man.... etc. etc."  It's all risk assessment.

:The key point about giving rather than selling is that there is little incentive to lie in response to the 'personal' questions if there is no financial incentive.--[[User:JBellis|JBellis]] 14:23, 29 December 2006 (UTC)

:I don't know the whole answer to this question, but I think besides being a more involved process, plasma is "cleaned" of many viral or bacterial diseases that can be present in whole blood, so the risk of paying for it is lower.  Not sure about prions though.  [[User:NTK|NTK]] 20:36, 8 October 2007 (UTC)

::It's true, as said above, that someone who can get money for their donation is financially motivated to lie on the health-risk questions. So that's one reason not to pay for donations. Also, regarding the fact that Am Red Cross, for example, gets your blood for free but sells it for money, people usually forget that those phlebotomists have to get paid, and the ARC has to buy the truck, the laptop computers, the needles, tubing, bags, labels, iodine, alcohol swabs, food/drink, distribution system, lawyers, biz admin, etc. ARC says that it is a low-margin to break-even business. Maybe they make 1 or 3 percent more margin than they claim they do, but that still doesn't translate to having money to pay the donors.

: FWIW, I've had the reasoning given to me in two forms. First, the loss of blood causes a depletion of nutrients and triggers some bodily reactions, which will result in minor fatigue and your muscles seizing up more easily.

A reader of the German Wikipedia did notice that the headline picture is somewhat misleading - in reality nobody is striped so heavily and there will be no blood samples taken along with the blood donation. That's wrong. Sadly we don't have a better picture at hand so I think the  best plan is to modify the caption the of picture pointing the reader to the fact that this is a variant used by the US Navy - obviously showing a standard that is used in the field, this [http://www.navy.mil/view_single.asp?id=44248] shows the same setup and here [http://www.navy.mil/view_single.asp?id=41173] we have the blood samples again.

::: Yes, the technique demonstrated in this photo is genuine, resembling the ordinary practice of the American Red Cross. The tape is there to keep the needle from popping out. Between venipuncture and when the main bag begins to be filled, a sample of blood is drawn through the IV line into a smaller bag, and this bag is emptied into test tubes that go to the lab in order to keep hepatitis and HIV out of the blood supply and to label the blood with red/white/platelet cell counts. --[[User:Damian Yerrick|Dami'''a'''n Yerri'''c'''k]] ([[User talk:Damian Yerrick|talk]] | [[Special:Contributions/Damian Yerrick|stalk]]) 18:41, 22 April 2007 (UTC)

:That's the same size of needle they always used when I was able to give blood. However normally, for most of the procedure they have a light bandage that's not attached to anything on top of the needle, whose sole purpose seems to be to keep the donor from freaking out from seeing the needle.

::I'm an 8-time donor to the ARC in the USA. Nothing in that USN photo looks particularly different from standard ARC practice. I don't think that those are scissors, I think it is a plastic clamp that simply pinches shut the lumen of the tubing when the bag is full and it's time to stop drawing blood. They do tape the tubing to your arm in one or two spots to keep it from moving and thus moving the needle around. Potential donors, rest assured that the stuff in the photo is normal—nothing scary. [[User:Three-quarter-ten|—&nbsp;¾-10]] 21:32, 9 November 2007 (UTC)

I have donated over ten times, but I don't remember the number.  That looks typical of how donations are done when I donate.  The thing on the bicep is a tourniquet not tape.  Then there are two pieces of tape to secure the blue thing which holds the needle after donation is complete.  After the bag is filled, and the tape removed, the phlebotomist will hold the blue thing in one hand and pull on the tubing with the other.  The needle will go inside the blue thing and I think it locks in place.  The phlebotomist does not touch the needle once it has punctured the donor.  This would prevent potential injury to anyone who has to handle this stuff later.  The scissors under the elbow is clamp that is used to pinch the tubing.  If you follow the line near the donor's watch, you'll see that it splits.  One line goes down to the bag.  The other one goes to that yellow thing which has a needle inside.  The test tubes have rubber tops which get pierced by the needle allowing blood to flow into the tube.  I don't know what prevents the blood from flowing out when the tube is not there though.  Usually when I donate, the tubes are not filled until after the bag is filled.

== "Double red" and ALYX ==

Some potential info for the article:  Donations of two units of red cells at Blood Assurance are done with the ALYX machine.  One of it's side effects is a slight chill due to the return fluids being at room temperature instead of body temp. [[User:PrometheusX303|<span style="color:green;"><strong>Prome</strong></span><span style="color:blue;"><strong>theus</strong></span><span style="color:red;"><sup>-X303-</sup></span>]] 13:51, 4 May 2007 (UTC)

:Ha! I didn't read this earlier. I am not surprised about this! When I did a double-red for ARC in 2006, I was *freezing* for roughly the second half of the session. I was doing some heavy-duty [[shivering]]. It occurred to me immediately that maybe the return line was putting it back in me at less than body temp, and I asked if that was the case, but they said, "You haven't started getting the return yet!" Either the return flow is queued till the end, and my cold feeling was simply a result of being temporarily 2 pints low, or maybe they just told me a tall tale to keep me calm! :-) Anyway, within 1 minute of being done and standing up, I felt fine and no longer cold. Problem solved—now every time I donate I wear a ton of clothing—sweater, etc. [[User:Three-quarter-ten|—&nbsp;¾-10]] 00:16, 21 November 2007 (UTC)

== Restrictions on Who can Donate ==

Weight Restrictions

Maybe it should be specifically included somewhere that many organisations require the donor to be above a certain weight? I know in the UK, US and many parts of europe, the donor must be at least 50 kg or 110 lb. Not sure quite how wide spread this is though.
just a little bitter that I'm not heavy enough, [[User:141.2.246.31|141.2.246.31]] 17:16, 2 July 2007 (UTC)

Sexual Orientation

American Red Cross still will not accept blood from any male who admits to having homosexual sex.  They do this citing the gay population as being a "high risk" group for contracting HIV.  They do not even allow for donation if a gay male has been celibate for years and tests negative.  There has been some controversy about whether this is discrimination.

There are also restrictions (some temporary, some permanent) for the following situations.

Acupuncture

Allergy, Stuffy Nose, Itchy Eyes, Dry Cough

== Baby blood donation ==
I removed the statement that the Red Cross requires baby blood donors to be type O because I am not type O and received a phone call from the Red Cross office with whom I donate that my blood is eligible to be donated to babies.

I haven't added this into the article as I'm a wiki-virgin (this comment is my first foray!), but I thought it might be worth mentioning that in terms of who can donate blood, in the UK they won't let you give blood if you've had a baby within the past 9 months (http://www.blood.co.uk/pages/flash_questions.html).  I've no idea why not. [[User:Traveller palm|Traveller palm]] ([[User talk:Traveller palm|talk]]) 14:20, 26 February 2009 (UTC)

:Atypical antibodies in blood can change during pregnancy, so the wait is there to give the body's immune system time to sort it all out so that it shows up properly on the antibody screens they do when selecting a unit of blood to transfuse.  Undetected antibodies can cause severe problems during transfusion.  It isn't about disease, it's a quirk with the complex immunology of blood typing.

== Benefits: toxins ==

"In addition to excess iron, a small amount of other toxic chemicals (such as mercury, pesticides, and fire retardants) leaves the donor's blood stream"

I've removed this from the benefits section before, and I've no interest in getting into an edit war.  Yes, it's technically true, but that doesn't mean it should be in the article.

It's bad for the recipient: If someone actually does have some sort of significant contamination in their blood, they're putting it into a medical product.  That product then gets put into someone else, usually someone who is already in bad shape and cannot afford any problems they can avoid.

It won't help the donor: Most of these toxins would be removed from the body by normal metabolic processes anyway or are bound into something other than circulating blood.  Therapeutic phlebotomy isn't indicated for any poisoning but chronic iron poisoning (hemachromatosis).

It's either irrelevant or actively harmful.  It's from a marketing study, i.e. any half-truth they can tell that might get donors to come in.

This is also from the marketing article, and is quoted verbatim.  They do not give any supporting citation or specifics.

I'd propose deleting it and leaving it off unless and until some sort of real support can be generated for it.

Much like direct payment, benefits can induce people to lie about their health in order to donate.  I know selfless acts of charity don't sit well with the "me" generation, but they have a real effect on the safety of the blood supply.

== Too Long ==

This article is American in more ways than one in that is getting to be overweight.

Some proposals for daughter/merge articles:

1. History of blood donation, maybe just move information to [[blood bank]]history section.
2. Move anything related to Plateletpheresis to [[Plateletpheresis]], since this article is heavily redundant.
3. The controversy about MSM donations should probably be its own article.  This has been heavily discussed, and it's really more of a civil rights issue than a medical issue.  The reason for it is painfully obvious if you read CDC statistics on who has HIV in the US, but regarding MSM as "unclean" is definitely something that people will be offended by.

Some proposals for weight loss:

1. Remove the specifics on donor eligibility and replace them with more general statements.  The specifics listed are US standards, which are grossly similar to standards in Australia and Scotland (at least from what I can glean from their posted online questionnaires), but not exactly the same.

2. Remove the "donors for babies" section.  It's true, but it's WTMI for a general knowledge encyclopedia article.

3. The ferritin link to heart disease should probably be pared down some or removed.  It's new research.
[[User:Somedumbyankee|Somedumbyankee]] ([[User talk:Somedumbyankee|talk]]) 19:04, 30 December 2007 (UTC)

3. Please tell us more about ferritin. The article currently has Zero mention of Ferritin! How low is too low for males and females? Blood donation lowers ferritin: by how much?

In some countries they test your ferritin before donation, in some countries they don't. Can we list these countries who test and who don't test ferritin before blood donation?

I'm going to attempt to make this article meet [[Wikipedia:Good articles|Good Article]], if not [[Featured Article]], by the WHO day.  I will probably be making some [[WP:BOLD|aggressive]] changes to the article, along the following lines:

Subpages to be made:
#[[Transfusion transmitted infection]]
#[[Blood drive]]
#[[Plasmapheresis]] - split into daughter pages of treatment vs. donation

*(Generally) Lead: Whole blood vs. apheresis

*(Generally) Process section: reads too much like instructions.
** "Preparation" section: remove per [[WP:NOTMANUAL]]
** "Screening": restructure to:
*** Legal aspects (paid or not, consent, deferral registries, etc...)
*** Medical/social History (current article has WTMI on vCJD)
*** Physical findings (BP, pulse, Hgb/Hct link to main article at Blood Test)
*** Testing (WHO-recommended tests, other diseases to be tested for, methodology)
** "Donation": Split by component
*** Whole Blood - cover here, point to main article for the processing
*** Plasmapheresis - point to main article
*** Plateletpheresis - point to main article
*** Apheresis RBCs
** "After the donation": cut Recovery and Post donation information into following section-
*** Recovery (bandaging, time to restore lost blood, time before next donation)
*** Complications (section content is fine, could use some copy editing, formatting, and sourcing)
** Benefits and Incentives (section content is fine, some formatting and copy editing needed)
** Types of donations
*** Allogeneic (brief note explaining that this is "default", baby donor *briefly*)
*** Autologous (section is fine)
*** Directed (historically relevant)
*** For Further Manufacturing (Recovered Plasma, Source Plasma)

==Comment by WhatamIdoing==

Snowman, while I appreciate your expertise on this issue, I'm a little concerned about some of your comments.  For example, you quote "blood type is often determined by the agency that collects the blood" and ask "which agency".  The answer to your question is contained in the quoted material:  "by ''the agency that collects the blood''."  Can you explain how to interpret this [[restrictive clause]] in a way that does not communicate that the agency that collects the blood is the agency that often determines the blood type?  (I can't.)
:But is does not say describe what sort of an agency it is, and I think that the language is not clear. Blood groups are usually done in blood banks or a laboratory, and an organization that collects blood may be a blood transfusion service (in the UK). Of course, a blood bank could be part of a blood transfusion service. I think that the line could be clearer, and I was aiming for more clarity in the article.  To me, the line that you quoted as an example is obviously vague and inadequate, and I feel that it was entirely appropriate to say that it had a problem. [[User:Snowmanradio|Snowman]] ([[User talk:Snowmanradio|talk]]) 22:50, 13 June 2008 (UTC)

::I don't think that a list of the kinds of agencies that might do this testing actually makes this sentence any clearer.  It might make the article more complete, and it would certainly make it more verbose, but there is no ''confusion'' here.  The reader is not left wondering whether the testing is often (but not always) done by the agency that collected the blood, or by some other unnamed agency.  The reader already knows:  it is normally done ''by the agency that collected the blood.''  The absence of concrete detail may not fully enlighten the reader, but it does not confuse him, either.
::Importantly, the general statement is applicable globally, in "ideal" situations as well as in shockingly inadequate ones.  Our statement holds true whether the agency is the national Red Cross, the U.S. Marines, the blood services department of a major hospital, or volunteers who self-organize after a major disaster.  The general rule, as stated, holds true in all these situations.  A sentence that says "blood typing is often done by blood banks" (for example) would not be true round the globe, and is certainly not going to be true in some emergencies.  I would be sorry to see this article remove ''accurate'' general statements in favor of specfic details that primarily refer to non-disaster situations in wealthy countries.

:::I am not even saying that the line should be modified. Of course, the line is correct as a generalisation.

I think that the line as it stands is unclear, and there are several ways to improve it or the section. The line may be modified or supporting information may be added.

:"The blood can also be transfused directly into the recipient." - the reference for this line is about historical methods, so this line is misleading as it could suggest that it is a common current option. Also, I think that a manual pumping device was used in the pipeline, and so the word "directly" in the line may to misunderstood to indicate that is is self powered process.  I have shown that two sections are littered with errors of emphasis and vagueness in the GA attempt process. I guess that you may be too close to the work yourself to copy edit the article (as you have indicated in your request of a peer review), and it is sometimes better for people who are new to the article to copy edit.

::The phrase you're mentioning makes no indication that it is common (it's listed as an "also" because it's not an equivalent process), but it is a valid way of performing a transfusion and it should be mentioned since it's combined with the donation process.  I need to do more research on this, because the WHO requiring a test for syphilis (which cannot be transmitted in stored blood because the spirochetes don't survive at refrigerated temperatures) implies that people are still doing it in developing countries.  It's a historical footnote for the developed world, but that doesn't mean that it's a dead practice worldwide.  When the article is vague, it's usually vague because transfusion medicine practices in the developing world aren't widely available on the internet and I would rather have the article be inconclusive than overly specific.

:::The reference to the phrase that I was referring to is dated 1989 (this date needs to be added to the cite) and is about transfusion in WWII and the Korean war. You are correct in saying that there is no indication on how common it is, but perhaps it should inform the reader of this fact as it is in current practice. If direct blood transfusion needs to be included (from veins or arteries) perhaps these are sufficiently different to need a separate section. I fear that writing vaguely for everyone and include historical footnotes in the same section might confuse everyone. It might be best to be explicit and explain the use of the various methods. I think the article needs more work, but please do not be disheartened, I think that you have done a good job almost single handed, and sometimes it takes a team of editors weeks or months to get an article to GA.

To a certain extent, I just wanted to cover that these could be done, but it appears that this is creeping into a major new activity for the article (it seems more an issue for [[transfusion]]).  One issue that was just added.  Clotting factors shouldn't be a problem for direct transfusion, the main advantages would be that it's oxygenated if arterial (the alternative for stored blood is [[ECMO]]), and the 2,3-DPG levels are optimal (2,3-DPG levels are one of the main problems with current storage methods).  Clotting factor preservation shouldn't be a big deal.  Unless this can be cited, I don't see a reason to keep this statement.

This was removed from the article, see the previous discussion above.  If it were to be included, it would have to be cited (the cites are listed above).  Considering it's not an effective way to lose weight, it's not a benefit in the usual sense.  The number is something that is of possible interest, and I guess I could see including it as a "fact about donations" in the section with hemoglobin replenishment, etc...  

There is no "lighter side" to the document: it's an encyclopedia article.  It needn't be boring, but it should stay pretty dry.  [[User:Somedumbyankee|SDY]] ([[User talk:Somedumbyankee|talk]]) 01:05, 18 December 2008 (UTC)

:I thought blood was pretty wet.  And "lighter side" was a play on the body weight topic. I added the note about calories in blood because this question pops up here and there on the internet (and not just on the vampire sites).  People mistakenly think that since a pint is a pound, they are donating a pound's worth of calories, i.e. 3500 kcal. And thus think they are either losing real weight (the anorexics) or use it as an excuse for a beer and food bash (the frat boys). Unfortunately, there is no citation. Doing the calorie math for the components of blood yields 400 to 500 calories. Plasma protein, lipid and glucose are 100 of that, hemoglobin in RBCs 300, the rest is for the unknown amount of calories from non-hemoglobin protein and membrane lipids of the RBCs. For some reason the Mayo Clinic FAQ on blood donations says 650 kcal, but they don't reference it or show the math. If you are willing to consider putting it back, I like "On the lighter side, does donating blood equate to losing weight? The answer is "Not really." While a pint weighs a pound, there are fewer than 500 calories in a pint of blood, or about the same as in a small meal."

::What you're describing, David notMD, is something called [[WP:OR|Original Research]] - you're synthesizing something for the article from other facts you know. That's really not considered ok for Wikipedia articles - if you had a source saying that a pint of blood was 500 calories, then that would be one thing, but doing some math yourself and saying that 500 calories is a fact isn't really what we do here. So if you want to add and cite the Mayo Clinic number, then we can talk, but just adding 500, especially in light of a conflicting reliable source (Mayo), isn't going to fly. In addition, encyclopedias don't do plays on words - it's rather unprofessional, for lack of a better term for it. We write fact, not humor. And finally, Wikipedia is not a FAQ - we don't use a question and answer format like you're suggesting. I agree with SDY that if the (cited) calorie count goes into the article, it belongs in the facts section as a one-line note.

::::In fairness to David, the info is not irrelevant to an encyclopedia, in the sense that when some users click the TOC at "#Benefits and incentives", they are looking to jump down and find out whether it is true that weight loss is a benefit of blood donation (answer = no).

==Blood shortages --are people dying due to lack of donations?==
I'm having trouble finding any sources relating to the number of deaths related to a shortage of blood donations. Are people dying due to lack of blood supplies? According to [http://www.gao.gov/new.items/d021095t.pdf this source]], I am lead to believe that no one in the USA dies from a lack of blood donations. Is there any information about other nations (particularly developing nations)?  I think a discussion about the adequacy of current blood supplies is very relevant to this article. I am particularly interested because of the [[MSM_blood_donor_controversy]]. I am looking to see if an arguement can be made that the risk of people dying due to blood shortages outweighs the increased risk of passing on diseases. According to the [[http://www.fda.gov/biologicsbloodvaccines/bloodbloodproducts/questionsaboutblood/ucm108186.htm FDA website]] the risk does not, at least as far as the USA is concerned. What about other countries?  Any insight on this issue is appreciated. --[[User:Tea with toast|Tea with toast]] ([[User talk:Tea with toast|talk]]) 06:20, 19 April 2010 (UTC)

:Lack of donation isn't usually the problem in the developing world, it's lack of logistics: having the blood is only the first step in a fairly complicated and possibly dangerous process.  I don't have a whole lot of info about specifics, but you could try searching around [http://www.dhhs.gov/ophs/bloodsafety/index.html here], the [[Department of Health and Human Services|DHHS]] advisory committee that exists to address the safety/availability balance.  They should have meeting minutes in there somewhere, and I'm guessing the question has come up.  [[User:SDY|SDY]] ([[User talk:SDY|talk]]) 02:28, 20 April 2010 (UTC)

== Titmuss ==

While I can verify that Titmuss did in fact exist and made some assertions about altruism and blood donation, I'm concerned that the proposed addition to the article overstates his importance.  At the very least, I'd like to see some [[WP:V|verification]] on what he "established."  Altruism (or benevolence, as argued by a 2005 article in J Med Ethics), has always been a common motivator for blood donation.

I'm a little concerned that I've never heard of this guy, and I've been working with blood banks for eight years now.  He had an opinion, certainly, but our article on him suggests that he was well-intentioned but not particularly influential.  That the [http://www.gao.gov/new.items/d02754.pdf GAO report] discussing payment of donors never mentions his name is a little troubling if he is truly that influential.

He's no Landsteiner.  [[User:SDY|SDY]] ([[User talk:SDY|talk]]) 01:57, 22 April 2010 (UTC)

:At the very least I'd like to see some sources, because I'm not finding much with "the Google."  It's possible that he's a local British phenomenon, and from what I'm reading a very generational (post-war) phenomenon.  I'll admit that my bias is very much towards a technical and legal approach to the topic rather than the philosophy and history.  I'm curious about the text of [http://www.who.int/bloodsafety/voluntary_donation/en/ World Health Assembly resolution 28.72] of 1975, which is much closer to the time of Titmuss, but it's not available online so far as I can find.  That the WHO's page on voluntary blood donation policy doesn't mention him is also troubling.  [[User:SDY|SDY]] ([[User talk:SDY|talk]]) 20:01, 23 May 2010 (UTC)

::I am not surprised if WHO's page on voluntary blood donation policy does not mention Titmuss, since his importance is not in blood donation policy but in the wider human sciences, and the reason for citing his work here is to give blood donation the credit it deserves for enabling him to argue convincingly that altruism is a real phenomenon, despite the efforts of many philosophers, psychologists, anthropologists and politicians to claim the contrary.  
::I am however surprised that SDY is unaware of him.  Perhaps the patronising observation about him being a “local British phenomenon” may suggest why; certainly the remark that Titmuss was “a very generational (post-war) phenomenon” implies that this article has no business dealing with the history of blood donation and its influences on the social sciences - an implication with which I disagree.  
::Titmuss’ work on blood donation was for long seen as a ‘’locus classicus’’ on altruism, and he has had a substantial influence on anthropology. I do not have leisure at present to consult a range of published references, but it’s clear that his work The Gift Relationship : From Human Blood to Social Policy (1970) was greatly influential in its day, and has recently been republished because of its renewed relevance in contemporary debates about organ donation.  
::In that context I think that SDY’s deletion of my contribution on Titmuss was cavalier, and I am disappointed that after inviting me to talk he failed to engage with what I said before simply deleting it again.  I invite him to consider that there is room for more than one vision of what this article should contain.

:::I have a lot less concern about what was just added to the article, since it isn't quite as gushingly enthusiastic and is actually sourced.  Just saying "this guy is super-important" when he is far from a household name, even in the blood banking community, is [[WP:V|likely to be challenged]].  Honestly, the reason cited in a recent [[America's Blood Centers|ABC]] newsletter discussing the allowable incentives for blood donors (i.e. what "gifts for gifts" are not considered payment) explicitly leaves it on the door of addicts that wanted money for drugs, one of the painfully obvious high risk populations which should not donate blood (for the rest of their lives by current US standards).  The bottom line reason why paid donors are currently considered dubious is as simple as "Does the donor have an incentive to lie about risky behaviors on health screening?"  Titmuss appears to be part of history rather than a major modern influence, and he's definitely worth mentioning on that aspect, but claiming that he's overwhelmingly important now does not seem to be justified from what I can find and from what I have experienced.

== Recovery and time between donations ==

Just found a minor mistake / misleading in information in " Recovery and time between donations " section.

the recovery time for donor from HK is 3 months for male and 4 months for female.
6 months are only for the teenage who under 18 but above 16.
the old statement wasn't completely incorrect but i feel that it is a bit of misleading and people from HK might think they should go and donate every 6 months.

== "650 Calories" claim ==

Here's what I (with help from others) have been able to dig up regarding sourcing of the claim that donating blood uses "650 calories" (or 600, sometimes).

The Mayo Clinic page mentioned above: http://www.mayoclinic.org/donateblood/know.html was changed into a redirect sometime between Oct 10, 2008 and Feb 26, 2009 (per the [https://web.archive.org/web/20080601000000*/http://www.mayoclinic.org/donateblood/know.html Wayback Machine]). The earliest archived version of the [https://web.archive.org/web/20081219101918/http://www.mayoclinic.org/donate-blood-rst/know.html redirected page] (Dec 19, 2008) includes the claim: "You burn about 650 calories by donating one pint of blood." However, it was removed sometime between [https://web.archive.org/web/20090226203125/http://www.mayoclinic.org/donate-blood-rst/know.html Feb 26, 2009] and [https://web.archive.org/web/20090901001632/http://www.mayoclinic.org/donate-blood-rst/know.html Sep 1, 2009], and does not appear in the current page: https://web.archive.org/web/20150323100120/http://www.mayoclinic.org/donateblood/know.html .

The claim has sometimes been cited to the whole of the [[University of California, San Diego]]. The earliest instance of this I've been able to find appears in this story in the Daily Mail on May 31, 2013: [https://web.archive.org/web/20130531235824/http://www.dailymail.co.uk/health/article-2333882/Donating-blood-good-YOUR-health-receiver.html Donating blood is as good for YOUR health as it is for the receiver] which says: "The University of California in San Diego estimate that for every one pint of blood donated, 650 calories are burned as the body must replenish itself." This was also claimed (around the same time), [https://web.archive.org/web/20130812103123/http://www.medicaldaily.com/why-donating-blood-good-your-health-246379 here]. Also around the same time, ( web.archive.org/web/20130627223406/www.opposingviews.com/i/health/new-evidence-suggests-donating-blood-has-health-benefits-donor (on WP blacklist)) repeated the claim, linking to [https://web.archive.org/web/20090226154136/http://edition.cnn.com/2000/HEALTH/04/26/give.blood.wmd/ a CNN article from 2000], which, sadly, doesn't mention anything about calories. [[User:JesseW/sig|JesseW, the juggling janitor]] 03:27, 27 July 2015 (UTC)

:{{u|JesseW}} Hmm, sounds like potentially one for Snopes then! [[User:Jfdwolff|JFW]]&nbsp;&#124;&nbsp;[[User_talk:Jfdwolff|<small>T@lk</small>]] 10:11, 29 July 2015 (UTC)

I added a bit of detail on the calorie math in the Invigoration/Benefits section of Talk.[[User:David notMD|David notMD]] ([[User talk:David notMD|talk]]) 20:39, 16 February 2016 (UTC)
:Calories was deleted as a donor benefit and I have refrained from reposting. There are two ways to think about the question: A) calorie content of the donated blood, which is closer to 500 than the sometimes mentioned 650, and B) the energy cost of synthesizing the replacement cells and plasma components - which has never been measured and would be extremely difficult to measure, given as plasma gets replaced within two days, but red blood cell replacement takes up to 60 days. So, no answer to the question of calories per donation, except clearly not a pound's worth of calories even though the 500 mL donation weighs roughly a pound.[[User:David notMD|David notMD]] ([[User talk:David notMD|talk]]) 23:25, 11 March 2017 (UTC)

== Assignment 5 ==

Summary:

The start of the article starts with a basic definition of blood donation: "A blood donation occurs when a person voluntarily has blood drawn and used for transfusions and/or made into biopharmaceutical medications by a process called fractionation (separation of whole-blood components)". The introduction continues to briefly explain important aspects such as types of donors, evaluations of donors, and collections. Most of the information in the introduction is short and only discusses the major aspect of blood donation, lacking a lot of information which is explained more in-depth later in the article. An interesting factor of the introduction section is the redirection to other Wikipedia articles that have little to do with the subject but share similar names:

"Give blood" redirects here. For other uses, see Give blood (disambiguation).

Blood donor" redirects here. For the TV episode, see The Blood Donor.

I like how the creators of the article valued efficiency for the readers when making the article. Overall, the introduction is a short, brief, but informative section regarding the topic of blood donation.

The rest of the articles in mainly divided into 8 different contents "Types of donation", "Screening", "Obtaining the blood", "Recovery and time between donations", "Complications", "Storage, supply and demand", "Donor health benefits", and "Donor compensation". Some sections such as "Complications" and "Storage, supply and demand" have an extensive and in-depth analysis regarding the content and the subject. However, "Donor health benefits"'s, and "Donor compensation"'s have a small section that can be expanded on by just my personal knowledge alone. These are the sections that I plan on improving. Contents such as "Screening", "Obtaining the blood" (which I think should have a better title), and "Storage, supply and demand" have subheadings that explain the contents further but I feel that some other contents could benefit from subheading too (again, "Donor health benefits" and "Donor compensation").

One of the major contributions to the article's length in the references with a total of 115 sources. In addition, the article offers related readings(that aren't associated to Wikipedia) that the reader can quickly assess if any of the subjects pique his/her interest. The offered readings include: "Blood Donation and Processing", "How youths are supporting on blood emergency in Nepal?", "Deferred Donors: Anemia & Blood Donation", "British guidelines for transfusion medicine", and "Definitive guide for safe blood donation". Another important aspect of the article is the "See also" tab in the articles that directs the user to related Wikipedia articles: "Blood substitutes", "History of blood donation", "James Harrison (blood donor)", "List of blood donation agencies", "Men who have sex with men blood donor controversy", "Xenotransfusion", and "World Blood Donor Day". This is important concerning the topic of blood donation because it belongs to a major part of medical and biological subjects, and thus are closely related to other topics. If the reader is interested in blood donations, perhaps blood donation agencies will interest him/her as well as any controversy and substitutions of blood donation.

'''The REAL ASSIGNMENT'''

Blood Donations During Natural Disasters:
Blood donations tend to always be high in demand with numerous accounts repeatedly stating periodic shortages over the decades (Sass). However, this trend is disrupted during national disasters.  The trend demonstrates that people are donating the most during catastrophes when, arguably, donations are not as needed compared to periods without disasters (Sass).  From 1988 to 2013, it has been reported that there was a greater number of units donated (that is over 100 units) than used on patients for every national disaster (Schmidt). One of the most notable examples of this pattern was the September 11th attacks.  A study observed that compared to the four weeks before September 11th, there was an estimated increase of 18,700 donations from first-time donors for the first week after the attack (about 4,000 to about 22,700) while repeat donors increased their donations by 10,000 per week (about 16,400 to 26,400) (Glynn, Busch, Schreiber).  Therefore, in the first week after the attack on 9/11, there was an overall estimated 28,700 increase in donations compared to the average weekly donations made four weeks prior to the attack.  However, despite the substantial increase of donors, the rate that first-time donors would become repeat donors were the same before and after the attack(Glynn, Busch, Schreiber), demonstrating that for many donors, donations shortly following the attack were a one-time occurrence.   The occurrence of September 11 is evidence showcasing that many people who meet the requirements to donate do not donate as much as they could (Glynn, Busch, Schreiber).  To better understand the reasoning for the influx of donations, one must understand the core reasons for donating blood in the first place.  Multiple studies have shown that the main reason people donate is due to “altruism”, general awareness regarding the demand for blood, increased confidence in oneself, helping a personal friend/relative, and social pressure(Edwards and Zeichner).  The reason for the increase in donations is most likely due to altruism and national pride.  On the other hand, lack of blood donations can occur due to fear, lack of faith in the medical professionals, inconvenience, and the lack of consideration for donating(Drake).

The Need for Blood Donation
The American Red Cross states that each day an estimated 36,000 units of red blood cells are needed (American Red Cross) with not enough donors to match the demands.  Most shortages during the year occur between July 4th and Labor Day as well as between December 25th and January 1st.   Not to mention, there isn’t a consistent demand for each blood type.  One type of blood being in stock does not guarantee that another type is.  Blood banks may have some units in stock but lack others, ultimately causing the patients that need units for specific blood types to have delayed or canceled procedures (Glynn).  Additionally, every year there is an increase of around 5-7% for transfusions without an increase of donors to balance it as well as a growing population of elderly people that will need more transfusions in the future without a predicted increase in donations(McCarthy).  Along those lines, it is known that blood can expire and have a limited shelf life[90], making it essential for donors to continuously donate blood.

== Short description ==

The current description is incomplete. Currently it's having blood drawn voluntarily. That's phlebotomy, if it's any single word. Blood ''donation'' is actually having blood drawn ''for medical use as a treatment'', including either transfusion or creation of pharmaceuticals. Is that too long?

:[[Wikipedia:Short description]] says it should be "''around 40 characters''." That means that even the present short description is actually a bit long. It's a tough limit to satisfy. Many of our short descriptions are quite poor because of it. [[User:HiLo48|HiLo48]] ([[User talk:HiLo48|talk]]) 02:12, 13 December 2020 (UTC)

== The pictogram ==

The pictogram at the start disturbs me. It looks like someone holding their arm to their head as if they have a massive headache, or recoiling from something extremely unpleasant. Where did it come from? Is it something official? I recommend removing it. [[User:HiLo48|HiLo48]] ([[User talk:HiLo48|talk]]) 22:54, 1 February 2025 (UTC)
