This is fascinating, thanks for sharing. Are there more groups than just A, B and O?

- bearmode 4y agoThe ABO group system relates to a gene called ABO, which gives you your A, B, AB, or O type. I'm not aware of any other blood types in that system (though I'm just an eager blood donor, not a haematologist). There are lots of other systems though that add up to make your blood what it is. There's the Rhesus (Rh) system I mentioned before, but the main ones also include the MNS system, the P system, the Lutheran system, the Kell system, the Lewis system, the Duffy system, and the Kidd system. As far as I know, Kell is the third most immunogenic system after ABO and Rhesus.
- roywiggins 4y agoThey apparently discover new sets of blood groups every few years, there are some vanishingly rare types. https://www.wired.com/story/new-blood-types/ https://www.wired.com/story/new-blood-types/
