Passive agglutination

Agglutination reactions can be broadly divided into three groups: Active/Direct agglutination Passive agglutination Hemagglutination 1. Active agglutination Agglutination reactions where the antigens are found naturally on a particle are known as direct agglutination. In active agglutination, direct agglutination of particulate antigen with specific antibody occurs. Direct bacterial agglutination uses whole pathogens as a source of antigen. It measures the antibody level produced by a host infected with that pathogen. The binding of antibodies to surface antigens on the bacteria results … Read more
