Passive hemagglutination
WebFeb 24, 2024 · There are two forms of agglutination. They are the active agglutination and the passive agglutination. With active agglutination, the antigen occurs naturally on particle. With passive agglutination, the antigen must first be bound to an inert particle to detect an antibody.
