What should I know about selbsttest fur glutenunvertraglichkeit schritt fur schritt?

A home test for gluten intolerance (e.g., NutriCheck I) is typically an IgG blood test. Steps: 1) order the kit, 2) collect a blood sample via finger prick, 3) mail the sample to a lab, 4) receive a report listing foods and IgG reaction levels. **Critical caveat:** IgG antibodies to gluten reflect dietary exposure, not intolerance or celiac disease. Major medical guidelines explicitly reject IgG testing for food sensitivities due to lack of clinical validity. A positive result does not mean you need to avoid gluten. If you experience symptoms like bloating, diarrhea, or fatigue, seek proper medical evaluation (e.g., tTG-IgA serology, endoscopy). This home test may offer insights but cannot diagnose gluten-related disorders. Evidence grade: marketing/unclear. Use the results as a conversation starter with a healthcare provider, not as a diagnostic tool.
