Question

Quizplus · Accepted Answer

The definitive test for diagnosing celiac disease is a biopsy of the small intestine. This involves taking samples of the lining of the small intestine to check for damage and inflammation characteristic of celiac disease. Antigliadin and antigluten antibodies can be detected in blood tests, but are not definitive diagnostic tests on their own. Genetic testing can be helpful in identifying individuals who may be at increased risk for developing celiac disease, but it is not a definitive diagnostic test for the disease itself.
