Are Agglutinogen and Agglutinin the Same?

The key difference between Agglutinogens and Agglutinins is that the agglutinogens are any type of antigens or foreign bodies which activate the making of agglutinin antibodies while the agglutinins are antibodies generating by our immune system against antigens.

What is the Agglutinogen?

agglutinogen Any of the antigens that are present on the outer surface of red blood cells (erythrocytes). ... Antibodies in the plasma, known as agglutinins, react with the agglutinogens in blood of an incompatible blood group (see agglutination).

Is Rh an agglutinin?

Those red cells which are Rh-positive contain agglutinable factors cor- responding to these three agglutinins, which Wiener has termed Rho, Rh', and Rh". These factors occur, either singly or in combination, to form at least five (probably seven) different agglutinogens or antigens.
