I wonder whether the author(s) would like to add a sub-topic on how blood is inherited from parents. A simple guide to, For example: If my parents are O+ & O- what blood type am I likely to be, sort of thing. If this is already in the article then improved indexing is needed. Wikipedia is about finding simple to understand answers to questions with access to further reading and greater understanding. I could not easily find the answer to this question in this lengthy in depth text. Thank you for reading. — Preceding unsigned comment added by Ianmurray5 (talk • contribs) 14:57, 1 April 2013 (UTC)
The reference for this data is a page written in Spanish, which unfortunately I can't read, but does anyone think that there's something wrong with the statistics on blood types in Argentina? I'm not an expert, but ABO genes and Rhesus genes are independently assorted, so you'd expect that to be reflected in the percentages of each type. So for example, Denmark's population has 35% O+ and 6% O- blood compared to 37% A+ and 7% A- blood, so the per-centages of O and A types that are Rhesus negative are 14.6 and 18.9 respectively, and the difference may well be exaggerated by rounding. In Argentina's case we have 85.4 & 8.4 and 34.26 & 0.44%, ie 8.95% are negative if they're O types compared to 1.27% of A types.Umbl (talk) 04:23, 28 January 2009 (UTC)
Actually, having looked at the reference again and jammed it through an online translator, it looks like a careless misuse of data. The numbers given for O-, A-, B- and AB- are in fact all the per-centages of Rhesus D negative for a sample of Argentians, but the 4 are noting how it combines with Rhesus C/c and E/e antigens - nothing to do with the ABO groups at all. These number have then, logically, been subtracted off the overall values for the ABO groups to give the O+, A+, B+ and AB+ figures. So all the Argentinian figures are wrong. Since the reference does give the overall % for O, A, B and AB, and the overall % for Rhesus D negative (9.1%), I think I'll correct the table with figures assuming idealised independent assortment, as this will be much closer to the truth than is on there now. A better reference will need to be found.Umbl (talk) 07:20, 28 January 2009 (UTC)
It appears that there is some national variation in the usage of O (oh) vs 0 (zero). According to ABO blood group system#Nomenclature in Europe and former USSR, "parts of Europe the "O" in ABO blood type is substituted with "0" (zero), signifying the lack of A or B antigen." However, looking at the references, it appears that O (oh) is the dominant term in English text. If there is a question, the WP:ENGVAR policy states a preference for "retaining the existing variety". This article started using the O (oh) and appears to have used that term for most of its history. I'm therefor reversing [recent edits] and restoring the prior nomenclature. (Other editors have undone some of these changes already.) -- Tcncv (talk) 02:26, 1 February 2009 (UTC)
I've actually got an answer directly from the "Austrian Federal Ministry of Health" [1] regarding the controversy on the usage of "0" (zero, number) vs "O" (oh, letter) about the blood types;
they confirm the original terminology used by dr. Karl Landsteiner in 1901 for the classification is "0" (Zero); and the "O" (oh) variation is a probable mistake due to the similar shape between the number 0 and the letter O.
I can also give you the contact to talk directly with the Professor who sent me the answer. Francesco Crimella (talk) 16:39, 7 November 2015 (UTC)
The correct term is 0 (zero) but because of the use O (oh) to say zero, like double O seven (007) the confusion started long ago and now its just impossible to correct it!
The first paragraph states: "People who are blood type A will have Anti-B antibodies, blood type B will have Anti-A antibodies, blood type O will have both Anti-A and Anti-B antibodies, and blood type AB will have neither. ".
This contradicts the diagram at the top of the page for the types O and AB. juglugs (talk) 06:11, 29 September 2009 (UTC)
The first diagram asserts that people with type A red blood cells have anti-B antibodies. If a type A person has never been exposed to type B blood, why would they have any anti-B antibodies ?Eregli bob (talk) 12:34, 22 October 2009 (UTC)

The last sentence of the section "Cultural beliefs and pseudoscience" is very biased, with insufficient citations to back up its strong opinion. "exploited for profit the lay public's knowledge about serotypes" is a biased statement, derived from one writer's opinion (according to the citation). I suggest more information on the possible correlation between serotype and diet be added to this article, as well as a non-biased rewrite of the aforementioned sentence. --Kangabell (talk) 02:12, 14 July 2009 (UTC)
There is "no evidence" of any dietary link to blood type because no one in the medical or nutritional academic establishment has EVER studied the question in a scientific fashion, probably because it would be politically incorrect and professionally self-defeating to do so. The key point is that no scientific research has either proven or dis-proven these theories. The theory of loose dietary correlation relates to a much larger but also scientifically undocumented (so far) theory linking genetic makeup and dietary differences. The reference at the end of this section is a weblink to one M.D.'s self-published opinion piece that reads more like a book review and is mostly meant to promote universal vegetarianism (god bless, I am a vegetarian). This is hardly evidence of a groundswell of skepticism although I expect that many "professionals" like him with some type of vested interest will naturally express skepticism. Agree with writers above that this section fails the neutrality test, and inserted small changes trying to strike a more neutral tone. Jrgilb (talk) 01:36, 22 November 2009 (UTC)

The discovery of blood types in 1901 has been hailed as one of the greatest advances in medical history, but the breakthrough was then used by the Nazis to further their eugenics program, and claim the superiority of Germans -- mostly types A and O -- over Jews, Asians and others with a larger proportion of type B blood. The theory reached Japan in a 1927 psychologist's report, and the militarist government of the time commissioned a study aimed at breeding better soldiers. The craze faded in the 1930s as its unscientific basis became evident. It was revived in the 1970s with a book by Masahiko Nomi, an advocate and broadcaster with no medical background.
[Dr. Niigaki] added that only "superior" men like Prince Fuimaro Konoye, the Premier, who possesses "O," type blood, were fitted to fight Japan's diplomatic battles.

In Japan, using blood type to predict a person's character is as common as going to McDonald's and ordering a teriyaki burger. The association is akin to the equally unscientific use of astrological signs by Americans to predict behavior, only more popular.

Need to remove the following link:
This is some sort of crank site with significant racist undertones. More importantly the 1959 list of blood types by so called nationalities or races is pure garbage. It includes Hindus as a category!
The article refers to Human blood group systems to list the currently acknowledged blood group systems by ISBT. However, this linked article Human blood group systems has many errors and does not contribute much else to the topic that has not been explained much better here in Blood type. Therefore, I would like to ask the question whether it was not better to include this table of currently 30 blood group systems here and link 'Human blood group systems' to this article here. What do you think? --Firefly's luciferase (talk) 04:31, 29 November 2009 (UTC)
As mentioned above, this article here looks very good. With the target to bring this article back to the GA with some updates and corrections, I started reading through more closely. I realized that RhD has been used thru the article to refer to the D antigen of the Rh blood group system (see ISBT table). Although this is used colloquially very often, it does not reflect the standardized terminology of the blood group systems (see ISBT tables). One may use Rh D (with space) or only D antigen to refer to the D antigen of the Rh blood group system. Furthermore, there is no Rhesus blood group system although very often the Rh system is called this way. This is another misnomer that may be mentioned in the article but should not be used generally (see again official terminology). --Firefly's luciferase (talk) 03:44, 6 December 2009 (UTC)
In the table showing distribution of ABO blood types and Rh factors, in some cases adding the corresponding Rh+ and Rh- percentages for each ABO blood type rounds to a whole percent.

My question concerns the table in the section Plasma compatibility. Isn't the right version the one shown in this revision of the article?

I would add that we have what appears to be a contradiction: "individuals of blood group O can receive plasma from any blood group; and type O plasma can be used only by type O recipients." Yet in Blood cell compatibility we have: "Therefore, a group O individual can receive blood only from a group O individual, but can donate blood to individuals of any ABO blood group" — Preceding unsigned comment added by 72.52.96.11 (talk) 18:04, 22 February 2012 (UTC)
The charts are wrong. Type O is the universal donor, AB the universal recipient.

The linked charts refer to red blood cell compatibility only. The "contradiction" comes from assuming that red blood cell compatibility and plasma compatibility are the same thing, but there is a subtle difference: red blood cell compatibility is dependent on the antigens the RBCs carry, while plasma compatibility is dependent on the antibodies the plasma carries. RBCs can't be put into blood where donor's blood cells will be attacked, while plasma can't be put into blood where it will attack the recipient's blood cells. It's this difference that results in the converse compatibility charts. 76.27.125.226 (talk) 02:36, 16 December 2014 (UTC)

I have zero knowledge on this subject but have heard some wild claims to the effect that certain blood types are the result of alien engineering, etc. Despite the fabulousness of such claims, I think a Darwinian perspective on the evolution of blood types would not be uninteresting to the lay reader, as well as some insights into their biological significance, if any.

I have donated my blood and was wonder about a few things.. first of all one of my clients had to have a kidney surgery, she was billed twenty thousand dollars for three pints of blood... It is the same type that I have. That was just for the blood, storage and carrying process. My friends daughter has the same type and sells her platelets. She lives in Wyoming. Is their a market that could help me acquire some money. Times are a struggle for me and I just want to know is there somewhere I can find out if it would be a service that I could offer and I sure could use some financial help at this time... I have heard that their is a market for my blood type... It is in the RHnegative arena. L M Horstman
I have been in blood banking (donor) for the past fifteen years. Federal law prohibits monetary payment of any kind for blood or blood components which are intended for use as a transfusable (in other words to be given to a human). There are however plasma donation centers where "industrial plasma" is collected and the donors are "compensated for there time". This plasma is used for a myriad of things such as the production of testing solutions and reagents for testing equipment, cosmetics and shampoo (if you have ever used "high protein shampoo" that's where the protein comes from. The primary reason you won't get paid for your blood at a true donor center is that you will be asked a series of questions in a screening process and some are rather personal and considered to be high risk inquiries. If a donor is being paid they have an incentive to not be completely honest with their answers. This has been policy since the discovery of HIV and the various types of viruses that cause Hepatitis.

The use of the abbreviation RBC for red blood cell is probably accurate but it seems a little clunky and is unnecessary jargon that doesn't add much to the clarity of the article. Using the actual words would make many of the statements more self explanatory. I know the abbreviation is defined at the top, but why not use the simple words instead? The article switches between the two - sometime using "RBC", sometimes using "red blood cell".

Hey there! The second paragraph in the lede, beginning with "Many pregnant women..." appears to contain some great information. However, it doesn't seem pertinent to be in the lede as it applies to a very specific circumstance, and not about blood types in general. To put it more simply, it's not one of the first things someone would need to know when researching blood types.
As I'm not a subject matter expert on this, I'm not sure if there's a more appropriate place in the article for this. I believe it would fit best in a new section under "Clinical Significance," but I'm open to additional thoughts! Thank you! RedLinkJ (talk) 18:50, 26 September 2017 (UTC)
