This because AB- type has both A and B antigens but has no Rh antigen. 2. AB Negative type is not a great donor. Again due to absence of the Rh antigen but presence of A and B antigens, the AB- blood type donor can only donate blood to AB- and AB+ blood type individuals.
Blood Type Compatibility. Your ABO blood type is based on the presence or absence of the A and B antigens on your red blood cells. The A blood type has only the A antigen and the B blood type has only the B antigen. The AB blood type has both A and B antigens, and the O blood type has neither A nor B antigen.By the time you are six months old, you naturally develop antibodies against the antigens your red blood cells lack.or instance, a person with A blood type will have anti-B antibodies, and a person with B blood type will have anti-A antibodies. If you have type A blood, you cannot receive B blood because your body's anti-B antibodies will fight the B blood's B antigens.
