What determines blood type? The ABO blood group system is named mainly according to the difference in the agglutinogens (i.e. blood group antigens, there are A, B and H) contained on the surface of human red blood cells. As shown in the above diagram, a person with type A blood is one whose blood contains A antigens in red blood cells and anti-B antibodies in the serum; type B blood is one whose blood contains B antigens in red blood cells and A antibodies in the serum; red blood cells containing A antigens and B antigens and no antibodies in the serum are characteristics of type AB blood; while type O blood is determined by the absence of antigens in red blood cells and the presence of anti-A and anti-B antibodies in the serum.
