<<Disclaimer: Verify this information before applying it to your situation.>> The serological diagnosis of CD is made by these three tests (IgG and IgA anti-gliadin, endomysial (EMA) and reticulin (ARA). To obtain meaningful results, it is essential that the tests be performed on well-standardized test kits by experienced laboratory personnel. Because of these limitations the results may vary from laboratory to laboratory. I would advise sending the results to laboratories that specialize in these tests. Dr. Vijay Kumar
