Father Knows Best - S1-E9

Corrected entry: Dexter is in the hospital and the doctors say there are complications because he has lost so much blood. Later, it is revealed he has a very rare blood type, AB-. It is true that this is the rarest blood type in most populations but I remember learning that AB blood types are the "universal acceptors" because they have no antibodies and can therefore accept A or B type blood. Of course it is preferable to give him the correct blood type but if it was really urgent shouldn't they give him any blood he could accept?

Correction: AB+ blood is the universal recipient, not AB-. People with AB- blood can only receive A-, B-, O- or AB- blood type. However, this comprises about 15% of the U.S. population. If Dexter was type B-, he could receive O- and B- blood, which comprise about 8% of the U.S. population. And finally, if he got the short end of the stick and had type O- blood, like about 6.5% of Americans, he could only receive type O-.
