Agglutinogen

Definition

noun, plural: agglutinogens

Any substance that acts as an antigen to stimulate production of specific agglutinin.


Supplement

Agglutinogens in the blood are proteins existing on the surface of every red blood cell in the body. The kind of agglutinogens present on the red blood cells helps determine the blood type of a person. If a person has blood type A, his red blood cells are studded with agglutinogens A only. If blood type B, the agglutinogens present are only agglutinogens B. If blood type AB, both agglutinogens A and B are present. In blood type O, there are no agglutinogens on the surface of the red blood cells.


Word origin: agglutin(in) + -gen (production).

Synonym: agglutogen.
Compare: agglutinin.
See also: agglutination.

You also must remeber: blood clotting occurs when the receiver produces agglutinins against the donated bloodgroup --> O doesn't contain any agglutinogen and therefore can be donated to blood type A patient (which produces agglutinine B but there's no agglutinogen B in blood type O ) --> ...

Matching blood groups

Blood type O has no agglutinogens, BUT it HAS agglutinins a and b!!! Blood type A has agglutinogen A and agglutinin b. In the scenario of O giving to A why don't the agglutinin a (from blood O) and aglutinogen A (from blood type A) ...

Matching blood groups

you can remember: A has agglutinogen A and there doesn't produce agglutinine A but produces agglutinine B B has agglutinogen B and therefore produces agglutinine A AB produces no agglutinine and O both therefore O can only receive O because ...
