Can Zöliakie Test help with allergy?

A celiac disease test (e.g., HLA-DQ2/DQ8 or tTG-IgA) is specific for autoimmune gluten intolerance, not for allergies. Allergies involve IgE antibodies against food or environmental triggers. The MyBody-X DNA test focuses on metabolism and nutrigenetics, not allergy markers. Therefore, a celiac test cannot diagnose or rule out allergies. If an allergy is suspected, specific IgE tests or skin prick tests are needed. Evidence for overlap between celiac disease and allergies is weak; they have distinct mechanisms. Consult an allergist or gastroenterologist for proper evaluation.
