Hemagglutinin, any of a group of naturally occurring glycoproteins that cause red blood cells (erythrocytes) to agglutinate, or clump together. These substances are found in plants, invertebrates, and certain microorganisms.

The principle of Agglutination reactions are similar to precipitation reactions; they depend on the cross linking of polyvalent antigens.
