Truth in Television: Difference between revisions

** The whole aspect of the [[Trope]] in that AB- can only take AB- blood is false. The positive variant (i.e. AB+) is considered a universal receiver of Red Blood Cells (O- is the universal donor), which makes life much easier for the blood bankers, in that they can usually just grab a bag of any old blood type and they won't reject it. AB- (the [[Trope Namer]]) is only slightly more limited; they can receive any negative red cells but not positive red cells (as opposed to how the inverse is possible and is why AB+ is the universal receiver).

** The "universal donor/receiver" angle only works with components. Whole blood is uncommonly used in transfusion medicine at present; most blood products consist of specific processed components such as red blood cells, plasma, or platelets. O- is the universal donor for red cells; AB+ is the universal recipient for red cells. With plasma it’s basically reversed: O is the universal recipient, AB is the universal donor (Rh+/- doesn’t matter much in plasma). If you had to give someone whole blood it really ought to be exact match.

** Regardless of the above, it is standard practice to give patients only their own blood type. Even if one is a universal recipient, using another type is done only if you have no choice. Rarity isn't really an issue either, because if one has a common blood type meaning there are plenty of donors, that also means there are plenty of recipients to split it between.
