Antibody tests are done to find certain antibodies that attack red blood cells. Antibodies are proteins made by the immune system. Transfusion reaction Human blood is typed by certain markers (called antigens) on the surface of red blood cells camera.gif. If you get a blood transfusion, the transfused blood must match your type. Rh sensitization Rh is an antigen. The full name for this antigen is Rhesus factor. If a pregnant woman with Rh-negative blood is pregnant with a baby (fetus) with Rh-positive blood, Rh sensitization may occur. The baby may have Rh-positive blood if the father has Rh-positive blood. A type of hemolytic anemia called autoimmune hemolytic anemia is a rare disease that causes antibodies to be made against a person's own red blood cells. The direct Coombs test finds antibodies attached to your red blood cells. The antibodies may be those your body made because of disease or those you get in a blood transfusion. The indirect Coombs test finds certain antibodies that are in the liquid part of your blood (serum).
