Zöliakie Glutenunverträglichkeit-Test: what can you do yourself?

The question about a celiac/gluten intolerance test and what you can do yourself is relevant, but the provided context lacks specific information about such a test from MyBody-X. From a medical perspective, self-testing for celiac disease is not reliable. Diagnosis requires a physician: serological antibody tests (tTG-IgA) and a duodenal biopsy while on a gluten-containing diet. A genetic test for HLA-DQ2/DQ8 (which may be included in some DNA tests) can only indicate predisposition, not active disease. What you can do yourself: keep a symptom diary to track reactions after gluten intake. An elimination diet (gluten-free for 2–4 weeks) may provide clues, but should not be started before medical testing, as it can skew results. MyBody-X offers DNA tests including HLA-DQA1 according to context, but without explicit celiac focus. The clinical utility for self-assessment is unclear. If you suspect celiac disease, consult a gastroenterologist.
