Why is there such a big deal made about rare blood types when a universal donor can donate to anyone?

>>76554004 (OP)
Universal donor colloquially refers only to the A, B and Rh antigens. However there are many more antigens present, and so a true universal donor - one having none of these other antigens present either - is extremely rare, hence a big deal is made about them.

Genius.

So that they can save the O- blood for the rare guys (plus themselves). Universal donors aren't that common so if you just gave away their blood to everyone then a substantial minority just get fucked

>>76554105
Right. I donate for my fellow O- but the rare types are so rare that I don't mind if they take a bit.

>>76554105
Almost everyone gets O they mostly sell the other types to labs for fundraising. There's just too many opportunities for accidents otherwise as well as having to diversify your blood stock having inherent storage and logistics problems.

Giving your blood away for free to blood salesmen is peak capitalism.

Most of the donated blood is used to save the lives of junkies and alcoholics because they tend to get into the most life threatening accidents. If I could donate blood to specific causes like leukemia and be sure it wouldn't be deferred to a large city for their druggie epidemic or sold to cover the bloated "operational costs" of a charity overflowing with enough paid staff to have a management structure akin to a conglomerate I would. But until that day I'm keeping it.

Redcross gave me a $15 dollar gift card

>settling for so low an amount
It's worth 15 times that

Radiolab had an episode on how they sell it for $150/pop like 10 years ago

AB negative is the most sigma blood type

the obvious solution is to eat more than $150 worth of the snacks they give you so you're in the black

There is no universal donor for the other antigens. There's only like a dozen other clinically significant antigens, and people with antibodies to them have to get antigen matched blood. SSA patients get a ton of transfusions so it's super common to see them getting (at least) C,E,K negative units. But with regards to rare blood types, that's talking about the people that have an antibody to a very high frequency antigen. So only 1% of units are going to be JSa antigen negative. Then if you combine that with them already having CEK antibodies, it can be a nightmare trying to source units for them. Don't feel like looking it up, but that could be like 1 in 1000 or 10,000 or something.

We should find incredibly retarded or brain dead people that are universal donors and turn them into massive, grotesque human blood-cattle sacks that we can harvest safe blood from. They could keep them in underground farms and make them obese and always hydrated.
