Immunoglobulin M (IgM) is the largest of several isotypes of antibodies (also known as immunoglobulin) that are produced by vertebrates. IgM is the first antibody to appear in the response to initial exposure to an antigen ; [ 1 ] [ 2 ] causing it to also be called an acute phase antibody.
The direct Coombs test detects antibodies that are stuck to the surface of the red blood cells. [1] Since these antibodies sometimes destroy red blood cells they can cause anemia; this test can help clarify the condition. The indirect Coombs test detects antibodies that are floating freely in the blood. [1]
An antiglobulin test (called the Coombs test) may be performed to determine the presence of a specific type of antibody. In people with cold agglutinin disease, the Coombs test is almost always positive for immunoglobulin M ( IgM ).
Anti-MAG antibodies can be readily detected in a patient's sera using various types of assays, but mainly an ELISA has been shown to be most effective. [ 1 ] [ 8 ] There are also various biological indicators, such as elevated cerebral spinal fluid proteins and elevated IgM monoclonal levels.
An individual with a chronic infection would test positive for HBsAg and total anti-HBc (IgM and IgG), but negative for IgM anti-HBc and anti-HBs. An individual who has successfully resolved their HBV infection will test negative for HBsAg, positive for anti-HBc, and may test negative or positive for anti-HBs, although most will test positive ...
The mononuclear spot test or monospot test, a form of the heterophile antibody test, [1] is a rapid test for infectious mononucleosis due to Epstein–Barr virus (EBV). It is an improvement on the Paul–Bunnell test. [2] The test is specific for heterophile antibodies produced by the human immune system in response to EBV
Antiganglioside antibodies that react to self-gangliosides are found in autoimmune neuropathies. These antibodies were first found to react with cerebellar cells . [ 1 ] These antibodies show highest association with certain forms of Guillain–Barré syndrome .
An antibody elution removes bound antibody from the surface of a red blood cell to aid in the antibody identification process. An antibody elution is a clinical laboratory diagnostic procedure which removes sensitized antibodies from red blood cells , in order to determine the blood group system antigen the antibody targets.
