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.
Autoagglutination of autologous erythrocytes.
autohemagglutination/au·to·he·mag·glu·ti·na·tion/ (aw″to-he″mah-gloo″tĭ-na´shun) hemagglutination caused by a factor produced in the subject's own body.
