Question

Part D A blood test that can be used to see if celiac disease is possible is the tissue transglutaminase (tTG)-lgA antibodies (tTG-lgA test). Why do you think this test is a good tool as a screening for possible celiac disease? Antibodies are produced by B cells of the immune system in response to specific antigens. In celiac disease, the immune system recognizes gluten as an allergen and produces antibodies against it. Antibodies are produced by inflammatory processes. When the mucosa of the small intestine is inflamed, these cells produce antibodies. Antibodies are produced by damaged cells. When the mucosa cells are damaged, levels of this antibody will increase.
