Detailed explanation-1: -There are 5 main Rh antigens on red cells – C, c, D, E, e. The most important of these is the Rh D. Having the D antigen on the red cell gives you the positive (+) and lacking it gives you the negative (-) after the letter A, B, AB or O.
Detailed explanation-2: -The Rh antigens are expressed as part of a protein complex in the RBC membrane. This complex is only expressed in cells of the erythroid line, and therefore Rh antigens are only expressed in RBCs.
Detailed explanation-3: -Rh blood group About 85% of the population express the D antigen and are called RhD positive; the remainder are termed RhD negative.
Detailed explanation-4: -The Rh factor is an inherited protein that can be found on the surface of the red blood cell. If your blood type is positive, then your blood cells have the Rh protein. If your blood type is negative, then your blood cells lack the Rh protein.
