Blood Group Types Explained. 1  Your blood group will be A, B, AB, or O. If you have A B or O blood group, you have antibodies in your blood plasma that destroy some of the other blood groups. 2  Your Rh status will be listed as negative (-) or positive (+).
Blood type is determined by the presence or absence of two particular antigens (molecules) on the surface of a person's red blood cells, antigens A and B. If the person's blood only has A antigens, it is type A; if it only has B antigens, it is type B. If the person has both antigens, her blood type is AB.
