So I guess the only people that wouldn’t be able to get any sort of transfusion (whether it’s whole blood or just plasma) is blood type B…..
which is what was Duncan’s blood type.[/quote]
Type A plasma has anti B antibodies so type AB is also not compatible with type A plasma.
Again, incompatible plasma in small amounts can be safely transfused so compatability should not really be an impediment given risk/reward.If you regularly receive platelet transfusions it is likely that at some time you received a type that was not the same as your own with incompatible plasma.
