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.
Antibodies to viruses that possess hemagglutinin antigens can be detected through a hemagglutinin-inhibition test. If a person or animal is carrying such antibodies, the agglutination of red blood cells will be prevented (see serological test).
