Screens for antibodies to parts of your own body indicating the presence of common autoimmune diseases, including the following:
- ANA (Antinuclear Antibody) test is a general test for the presence of an autoimmune condition and therefore may be positive with several autoimmune disorders, but the percentage of patients with with positive ANA results varies. Note that low level positive results can be obtained in a significant number of patients with a other types of disorders, even some healthy people.
- AMA (Antimitochondrial Antibody) tests for Primary biliary cholangitis is a chronic autoimmune disorder that causes inflammation and scarring of the bile ducts inside the liver.
- ASM (Anti-Smooth Muscle Antibody) tests for the liver disease autoimmune hepatitis and may also be seen in other forms of liver disease, such as primary biliary cholangitis (PBC).
- GPC (Gastric Parietal Cell Antibody) tests for autoantibodies, that target a type of specialized cells that line the stomach wall and/or intrinsic factor which can therefore lead to B12 deficiency.
- LKM (Liver Kidney Microsome type 1 Antibodies) tests for autoantibodies, that target liver enzymes, indicating type 2 autoimmune hepatitis.
- ATA (Anti-Thyroid antibody) tests for autoanitbodies involved in chronic inflammation of the thyroid (thyroiditis), this can lead to chronic conditions and autoimmune disorders associated with hypothyroidism or hyperthyroidism such as Graves disease or Hashimoto thyroiditis.
