(hē'mă-glū'ti-nin, hem-),
A substance, antibody or other, that causes hemagglutination.
Synonym(s): hemoagglutinin
Farlex Partner Medical Dictionary © Farlex 2012


A substance that causes agglutination of red blood cells, such as an antibody, or a glycoprotein found on the surface of a virus. Viral hemagglutinins enable viruses to bind to host cells.
