The Basics

Blood type is categorized according to the ABO system.

Red blood cells can have the antigens “A” or “B” attached to them. If you have the protein “A” attached to your red blood cell, you are blood type A. If you have the protein “B” attached to your red blood cell, you are blood type B. If you have both the “A” protein and “B” protein attached to your red blood cell, you are type AB. If you have no proteins attached to your red blood cell, you are type O.

You also may have Rh antigens on the surface of your red cells. If you do, that makes your blood type “positive” (+). If these antigens aren’t present, your blood type is negative (-).
