The Gliadin Deamidated Peptide IgG IgA Antibodies Test detects both IgG and IgA antibodies against deamidated gliadin peptides, highly specific markers for celiac disease. Elevated results indicate an autoimmune reaction to gluten that can damage the small intestine. Doctors use this test to confirm suspected celiac disease, evaluate unexplained digestive issues, or monitor compliance with a gluten-free diet, often alongside tTG and other celiac antibody tests.
The Gliadin Deamidated Peptide IgG Antibody Test detects IgG antibodies to deamidated gliadin peptides, helping diagnose celiac disease in patients with IgA deficiency or gluten-related disorders. Elevated levels indicate an autoimmune response to gluten that may damage the small intestine. Doctors use this blood test to evaluate persistent digestive symptoms, confirm celiac disease, or monitor dietary compliance with a gluten-free diet for improved health outcomes.
