    Full explanation: https://en.wikipedia.org/wiki/Blood_type

    A positive. AB negative. O positive. We've heard those terms before at least once - they're blood types.

    For those unaware, a blood type is determined by what antigens a person possesses in his or her blood. There are 3 primary antigens of interest: A, B, and Rh (technically a different name - that is the name of the system), and those combinations give rise to the 8 main blood types that people know of: A, B, AB, and O (meaning neither A nor B), with the + or - factor added on.

    Blood type is hereditary; everyone inherits types from their parents. This is most important for compatibility for blood transfusions; incompatible blood will cause an immune response, resulting in the death of the transfused blood cells. (For example, O negative has no special antigens, so they can give blood to anyone but only receive it from other O negatives - conversely, AB positive has all 3, so they can only give blood to other AB positives but can receive it from anyone.)

    If you know, what is your blood type? What does that mean for you?
    I write this topic simply because I'm curious and love working with data - and blood types sprung to mind today!

    I myself am A positive. Most of the world (to my knowledge) is A positive, so I suppose I'm rather ordinary in regard. I do have an AB negative (the rarest instance) somewhere in my genealogy, though I've forgotten exactly who.

    I'll update you on mine on Monday when I give blood, because I don't know right now what I actually am. Maybe we'll see a trend that Pokémon nerds gravitate towards a certain blood type. Then we can say for certain that being a trainer runs through our blood.

    Last I remember, mine is O-negative. I'd actually forgotten about blood types until now, but the last time I had thought of them was after reading a Marvin Redpost book as a kid (where the main character had the same blood type), and after having them included in our notes for a unit in seventh grade social studies.

    I got a blood test earlier this year and found out that I'm an O+.
    I looked it up online to see a chart of blood types (which can receive from which and which can give to which), and I can only receive from O+ and O-. :( But I can give blood to any positive blood type.
    2 of the sites I checked also said that O+ is the most common blood type, followed by A+. And here I was, thinking my blood type was something special. :P

    I'm the universal donor O+ even though both my parents are A+ XD

    We were all pretty puzzled as to why I was O positive even though the ones responsible for conceiving me were both A positive. I asked a science teacher in secondary school (high school) and she explained it to me.

    Turns out there's two parts to the 'alphabet' of your blood. So, let's take my parents; both of them A positive with an O positive child. Turns out the both of them have AO positive blood. Meaning that their dominant gene - which is A - is expressed while the recessive gene - the O - remains hidden.

    So I got the O's from both of their AO's hence why I'm awesome O! XD

    So now the only one in my family who does not know her blood type is my lovely sister. She has the possibility of having the combinations of AA, AO and OO.

    This also explains why parents have children with AB blood even though both of them only had A or B blood.

    I'm the universal donor O, but I'm unsure whether I'm positive or negative. I don't think I'll be needing that information for myself though as I won't be donating blood anytime soon (needle phobia). If I really do need that information, I could always find out from the blood test I did earlier this year.

    Don't be sorry - dominant and recessive alleles are one of the coolest things about genetics. Blood type is a perfect example of co-dominance showing up (A and B are both dominant alleles, whereas O is recessive).
    I myself am fairly sure that my alleles are AO, as I have one A parent and one O parent.



    I think the universal donor is actually O negative, since technically O positive can't give blood to any negative people.
    ...That sounded a lot less demeaning in my head.

    I'm A negative, which I think is a moderately good type for donating.

    My mother is O+, and I don't know my father's type. I think it would make sense that he's either A- or AB-, but I might be mistaken. To comment on the O- or O+ being the best donor above, it's O- that can give to anybody at all. O+ is almost as good for giving, but O- is the absolute best.

    I found out the first time I gave blood to Red Cross. I stopped giving them my blood a while back. Short story: RC spams my phone and email nonstop. One day I was giving blood and they called me asking for more blood while their needle was STILL IN MY ARM AND I WAS ACTIVELY BLEEDING OUT FOR THEM! I said "Eff this, I'm just going to start selling my blood at the hospital, I'm sick and tired of Red Cross' BS". Maybe their tactless marketing is a bad reason to stop giving them my blood, but at least the hospital is making it worth my while if I'm literally giving away my body to a stranger. Call me selfish, then talk to a person with healthy blood and who doesn't give at all.

    Edit: My blood hasn't gone to Red Cross in three years according to my donor card, and as I was writing this I got another email from them asking for my continued donation. They kind of seem like a jealous ex, desperately wanting me back even though I found someone better. Someone who treats me like a person when I walk in the door, not like a sheep to be sheared. Someone who actually gives my blood to people who need it instead of to labs. Someone who doesn't just leech off my generosity, but who reciprocates what I put into our relationship.

    I think O positive is actually the universal donor.

    Time to solve this debacle!

    https://en.wikipedia.org/wiki/Blood_type#Universal_donors_and_universal_recipients



    (emphasis added)

    So that would make O negative the universal donor for red blood cells. (Having neither the A, B, nor Rh D antigens, they will not cause immune responses in other blood streams.)
    But in the process, I learned that the exact opposite is true for donating plasma, since the plasma is what houses the antibodies:



    O-type plasma has antibodies to counteract A and/or B-type blood, whereas AB-type plasma doesn't have (or need) those. So when it comes to donating blood, O negative is universal, whereas when it comes to donating plasma, AB is universal. (It doesn't look like the Rh +/- factor applies for plasma.)

    Huh. I've learned something today! Very cool.

    If I remember correct I'm O-, the universal donor, so I can give blood to everyone but only receive it from other O- individuals. Is the other way around for Plasma. Kinda fascinating that the table completely flips when is plasma instead of red blood cells.

    Hospitals are always after more O- blood because is often overused as a result of it being accepted by all other types. I would donate but I'm pretty much getting tattooed every half year so I'm illegible for donating because of that.

    Weird. It was to my understanding that medevacs carry O+, although the writing I got that from is 10 years old and military medicine is far from civilian medicine lol

    Ooh, this thread is very unique! Both my twin sister and I are O positive, inherited from both of our parents. I don't think this means much to me, but I've read somewhere that people with O positive blood types can get really angry when something opposes their passion, which I found out is quite true, although we manage our anger. I've also heard somewhere that O positive people are very outgoing and social, which is the opposite of us since not many people prefer to be with us since we're different. I would love to, but nobody wants to get along with us. One of us twins (Ho-Oh) also doesn't like being near people (except for a few) which opposes that statement I mentioned earlier.

    I'm O+ which is the most common blood type I think, but at least it means I can donate blood to anyone.
    Speaking of blood types, I've always wondered why they're such a big thing in Japan. How Japanese game profiles often ask for your blood type, haha.
