It is a blood test that determines the levels of antitransglutaminase IgA antibodies in the body. This test is usually performed as a complementary test to diagnose diseases such as celiac disease and other autoimmune disorders.
Before performing this test, the patient will not change his diet and must continue to eat foods containing gluten (oats, wheat, rye and barley) such as bread, pasta or pastries.
By means of a small needle the extraction of blood is made and it is sent to the laboratory. When the doctor checks the result of the tests if an alteration is observed in the antibodies antitransglutaminasa IgA in blood it will mean that the patient can be celiac. On certain occasions, the doctor may request a biopsy of the small intestine to confirm the diagnosis. In case of positivity, the patient must follow the diet gluten free to avoid the discomfort derived from this disease.
