An example of an abnormal Ig is monoclonal protein, or M protein. The immunoelectrophoresis-serum test (IEP-serum) is a blood test used to measure the types of Ig present in your blood, especially IgM, IgG, and IgA. The IEP-serum test is also known by the following names: immunoglobulin electrophoresis-serum test.

Screening for hepatitis C is performed by measuring antibody to HCV (anti-HCV) in a person's serum. A positive test (detection of the antibody) is not a diagnosis of the disease; it only indicates that a person was previously exposed to hepatitis C.

Immunohistochemistry (IHC) is a method for detecting antigens or haptens in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues. The antibody-antigen binding can be visualized in different manners.

The Interferon Gamma Release Assay (IGRA) is a blood test used to see whether a person has been infected with Mycobacterium tuberculosis ( the bacteria causing TB). The IGRA test works by measuring the body's immune response to the TB bacteria. An IGRA test may be used to diagnose latent TB infection.

The presence of antinuclear antibodies (ANA) indicates the possibility of autoimmunity and the indirect immunofluorescence (IIF) assay on HEp-2 cells is the standard blood test (ANA-HEp-2) used to detect ANA. However, studies have shown that a “false-positive” ANA test occurs in up to 13% of healthy individuals.
