What should I know about glutenunvertr glichkeit testen?

Testing for gluten intolerance requires distinguishing between celiac disease (an autoimmune condition) and non-celiac gluten sensitivity (NCGS). For celiac disease, the gold standard is a blood test for IgA tissue transglutaminase antibodies (tTG-IgA), followed by an endoscopic biopsy if positive. Genetic testing for HLA-DQ2/DQ8 can rule out celiac disease but cannot confirm it. For NCGS, no validated biomarker exists; diagnosis is made by exclusion and a supervised gluten challenge. Crucially, IgG-based food intolerance tests (e.g., NutriCheck I) are not supported by major medical guidelines – they reflect dietary exposure, not intolerance, and can lead to unnecessary dietary restrictions. MyBody-X offers such tests, but the evidence is weak. Always consult a doctor before testing, especially in children or if you have digestive symptoms. Self-testing cannot replace a proper clinical workup.
