hemagglutination

 [he″mah-gloo″tĭ-na´shun]
agglutination of erythrocytes.
hemagglutination inhibition (HI, HAI) test
1. a highly sensitive procedure for the measurement of soluble antigens in biologic specimens; the amount of hemagglutination reflects the amount of free antibody present after reaction with the specimen and thus varies inversely with amount of antigen in the specimen.
2. a procedure for the measurement of serum antibodies directed against a hemagglutinating virus; the highest dilution of serum that completely inhibits hemagglutination by a standardized viral preparation is reported as the hemagglutination titer.

he·mag·glu·ti·na·tion

(hē'mă-glū'ti-nā'shŭn),
The agglutination of red blood cells; may be immune as a result of specific antibody either for red blood cell antigens themselves or other antigens that coat the red blood cells, or may be nonimmune as in hemagglutination caused by viruses or other microbes.
Synonym(s): hemoagglutination

hem·ag·glu·ti·na·tion

(hē'mă-glū-ti-nā'shŭn)
The agglutination of red blood cells; may be immune (as a result of specific antibody to red blood cell antigens or other antigens that coat the red blood cells), or nonimmune (as in hemagglutination caused by viruses or other microbes).
Synonym(s): haemagglutination.

Hemagglutination

The clumping or clustering of red blood cells caused by certain viruses, antibodies, or other substances.
