There are three serum tests (EMA, ARA, AGA) for the detection of celiac
disease. According to the criteria set forth by the European Society for
Pediatric Gastroenterology and Nutrition (ESPGAN), two of the three
serological tests must be positive for the diagnosis of CD. EMA has proven to
provide the highest degree of specificity and sensitivity. Results will vary
somewhat according to the expertise of the laboratory and the experience of
the laboratory personnel.

If you have any questions, I would be glad to hear from you.
