Types of Antigen-Antibody Reactions

Types of Antigen-Antibody Reactions

Serological tests are widely used for detection of either serum antibodies or antigens for diagnosis of a wide variety of infectious diseases (Table 14-1). These serological tests are also used for diagnosis of autoimmune diseases and in typing of blood and tissues before transplantation. The following are the examples of antigen–antibody reactions: (a) precipitation, (b) agglutination, (c) complement-dependent serological tests, (d) neutralization test, (e) opsonization, (f ) immunofluorescence, (g) enzyme immunoassay, (h) radioimmunoassay, (i) western blotting, ( j) chemiluminescence assay, and (k) immunoelec-tronmicroscopic tests.
