    The antigens you have or lack determine your blood group.

    Take the blood group with which people are most familiar: the ABO blood group.

    If you have antigen-A on your erythrocytes (red blood cells) you are blood group A.

    If you have antigen-B on your erythrocytes you are blood group B.

    If you have antigen-A and antigen-B on your erythrocytes you are blood group AB.

    If you have neither antigen-A nor antigen-B on your erythrocytes you are blood group O.

    Blood group O got its name from the German word 'ohne' which means 'without'.
