Question

Quizplus · Accepted Answer

Elevated levels of IgA and IgG gliadin antibodies are indicative of gluten-sensitive enteropathy, also known as celiac disease. This immune-mediated disorder is triggered by the ingestion of gluten, a protein found in wheat, rye, and barley. It is characterized by damage to the small intestine, which can result in malabsorption and various symptoms such as abdominal pain, bloating, diarrhea, and weight loss. Testing for gliadin antibodies is part of the diagnostic workup for celiac disease, along with other tests such as tissue transglutaminase antibodies and small bowel biopsy. Peanut allergy, lactose intolerance, and Crohn's disease are not related to gliadin antibodies.
