Hi doctor,

My friend had his deamidated gliadin IgG antibody test done recently. The test result is 152. Does it mean that the person is having celiac disease?

Welcome to icliniq.com.

Deamidated gliadin IgG antibody level of more than 30 is diagnostic of celiac disease. Since the number mentioned by you is 152, it indicates that the person is having celiac disease.
