Question of the Week / Re: QotW: 19.05.19 - Can a blood transfusion change my blood group?
« on: 11/06/2019 14:26:11 »
It's impossible. If donor blood has no proper group it may be very dangerous. Special blood groups have their own antibodies inherited antigenic substances on the surface of red blood cells. That's why blood with A group cannot be a donor for B group and conversely. Only having 0 groups you don't have any antigens so you may be a universal donor. Having AB group you have no antibodies and both antigens so you may be the universal recipient. So, blood transfusion cannot change your blood type, but it can kill you if you won't receive the proper group.
