Specializes in Allergy and Immunology

Genetics: You're talking about blood group antigens; sugars on the outside of the red blood cells unique to those with certain blood types. Those who have sugars "A" and "B" should not develop antibodies to these sugars, or else such antibodies would "attack" their own red blood cells (triggering lysis).
