This is why it?s important to perform blood type testing before blood transfusions. There are several types of surface antigens on blood cells, but the ABO and Rh antigens are the most common. Rh Blood Group: The Rh blood groups has two types, Rh positive and Rh negative. The Rh surface antigen is also called the D antigen.
