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 (+).
Human blood is typed by certain markers (called antigens) on the surface of red blood cells. Blood type may also be done to see if two people are likely to be blood relatives. The most important antigens are blood group antigens (ABO) and the Rh antigen, which is either present (positive, +) or absent (negative, -). So the two most common blood type tests are the ABO and Rh tests. The ABO test shows that people have one of four blood types: A, B, AB, or O. If your red blood cells have: The A antigen, you have type A blood. The liquid portion of your blood (plasma) has antibodies that attack type B blood.
