Comments

Serologic test results alone cannot establish or rule-out diagnosis of celiac disease. Consult Gasteroenterology for follow up on patients whose seology suggests celiac disease or whenever serologic test results do not fit the clinical presentation. See also testing for Endomysial Antibodies (EMA) as an additional serologic marker for celiac disease.
