How do ABO blood groups differ in their agglutinogen and agglutinin components

Agglutinogen is an antigen on the red cells that determine your ABO type. that stimulates antibody production. Agglutinins are the opposite antibody in the liquid or serum of the blood.
Type A = A agglutinogens on the red cell and B agglutinins in the serum.
Type B = B agglutinogens on the red cell and A agglutinins in the serum.
Type AB = A and B agglutinogens on the red cell and NO ABO agglutinins in the serum.
Type O = NO ABO agglutinogens on the red cell and A and B agglutinins in the serum.
