Immunologic test

In medicine and immunology, a immunologic test is any test that uses immunologic techniques.

Regarding types of substrates being tested:

• Immunoassays and serologic tests (serologic tests include agglutination tests) use blood samples
• Immunohistochemistry tests use tissue samples.

Regarding methodology:

• Immunoassays such as the enzyme-linked immunosorbent assay (ELISA) and Western blot, along with the tissue immunohistochemistry fluorescent antibody technique all test the direct binding of antibody to antigen.
• Serologic tests such as agglutination tests (including hemagglutination tests and latex agglutination tests) test secondary immunoglobulin and antigen interactions.
