wie lange gluten essen vor zöliakie-test — what can you do yourself?

For a reliable celiac disease blood test (tTG-IgA), you must consume gluten regularly for several weeks; otherwise, a false-negative result is likely. The recommended gluten intake is about 1–2 servings of wheat-based products per day (e.g., bread, pasta) for at least 6–8 weeks before the blood draw. For a genetic celiac test (HLA-DQ2/DQ8), no gluten challenge is needed. What you can do yourself: If you are already gluten-free, reintroduce gluten into your diet before testing – but only after consulting your doctor, especially if symptoms are severe. Home test kits (e.g., stool tests) are not sufficiently validated for diagnosis. MyBody-X does not offer a celiac blood test; its DNA and stool tests cannot replace a medical diagnosis. If you suspect celiac disease, seeing a gastroenterologist is the safest course.
