ABO blood types: A positive persons have "a" antigens on their blood cells, b-positive have "b". And ab positive have both. "o" blood cells have neither.

ABO antigens: The antigens expressed on the red blood cell determine an individual's blood group. The main two blood groups are called ABO (with blood types a, b, ab, and o) and rh (with rh d-positive or rh d-negative blood types).
