Agglutination reactions apply to particulate test antigens that have been conjugated to a carrier. The carrier could be … WebbThese reactions take part in two stages, sensitization and agglutination. In the first stage (sensitization), the antibody binds to the red cell or sensitizes it. In the second stage, the sensitized red cells agglutinate. Although sensitization occurs first, it and agglutination ultimately overlap to some extent.
