Celiac disease antibody tests are primarily used to help diagnose and monitor celiac disease, an autoimmune disorder caused by an inappropriate immune response to gluten, a protein found in wheat, and related dietary proteins in rye and barley. Celiac tests are usually ordered for people with symptoms suggesting celiac disease, including anemia and abdominal pain.Celiac disease blood tests measure the amount of particular antibodies in the blood. The most common tests include:Tissue transglutaminase antibody (tTG), IgA class — the primary test ordered to screen for celiac disease. It is the most sensitive and specific blood test for celiac disease and is the single test preferred by the American College of Gastroenterology, according to its 213 guidelines, as well as the American Gastroenterology Association for the detection of celiac disease in those over the age of 2 years. The IgG class of anti-tTG may be ordered as an alternative in those who have a deficiency of IgA. If the anti-tTG, IgA or IgG test is positive, then the test can also be used to monitor a person with celiac disease and to help evaluate the effectiveness of treatment; antibody levels should fall when gluten is removed from the diet. Although "tissue" is in the name of these tests, they are measured in the blood.Quantitative immunoglobulin A (IgA) test — ordered along with, prior to, or following an anti-tTG test to detect IgA deficiency, which occurs about 2-3% of the time in people with celiac disease and can lead to false-negative test results. If a person has an IgA deficiency, then a test to detect the IgG class of autoantibodies may be ordered.
