Your immune system ignores the surface antigens on your own RBCs. However, your plasma contains antibodies, sometimes called agglutinins , that will attack the antigens on foreign RBCs. When these antibodies attack, the foreign cells agglutinate , or clump together; the process is called agglutination . The plasma of a Type A, Type B, or Type O individual always contains either antiâ A or antiâB antibodies, or both, even if the person has never been exposed to RBCs that carry foreign surface antigens. If you have Type A blood, your plasma contains antiâB antibodies, which will attack Type B surface antigens.
Red Blood Cell (RBC) Antibodies What is a red blood cell antibody? An antibody is a protein made by your body. Antibodies usually bind to foreign substances, such as bacteria and viruses, and destroy them. A red blood cell antibody is one that âattacksâ red blood cells. Your red blood cells have certain âmarkersâ on them, called antigens. If your immune system sees a red blood cell antigen that is âforeignâ (such as from a blood transfusion), it will make antibodies to destroy it. How does a person get RBC antibodies?
