Tissue Transglutaminase TTG-DGP Screen

Tissue transglutaminase TTG-Deamidated gliadin peptide (DGP) screen is a diagnostic test to determine the presence of TTG and DGP antibodies in the blood. This test is used to diagnose a digestive disorder known as celiac disease.

In Celiac disease, the immune system produces antibodies against gluten that damage the small intestine. Gluten is a protein found in wheat, rye, barley, and other grains. Your doctor will recommend this test if you have celiac disease symptoms like anemia, chronic diarrhea, abdominal pain, weight loss, and bloating. The presence of tTG and DGP antibodies in the blood usually indicates that a patient has celiac disease.

Currently, there is no medication available for treating celiac disease. People having celiac disease should consume only gluten-free foods.
