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.
For this reason, they are called warm agglutinins even though they seldom directly agglutinate the RBCs. Rarely, IgM antibodies have these reaction characteristics and readily agglutinate red cells. (See Pathogenesis of autoimmune hemolytic anemia: Warm agglutinins and drugs.)
