What to watch with IgG Unverträglichkeitstest and Darmgesundheit?

IgG food intolerance tests (often sold as 'food sensitivity' panels) should be approached with strong skepticism. Scientific evidence does not support their use for diagnosing food intolerances or guiding gut health interventions. IgG antibodies are a normal part of immune memory and do not reliably indicate adverse reactions. Major allergy and immunology societies (e.g., EAACI, AAAAI) explicitly advise against these tests. They can lead to unnecessary dietary restrictions, nutritional deficiencies, and anxiety, while delaying proper diagnosis of conditions like lactose intolerance, FODMAP sensitivity, or IBS. A microbiome test (like MyBody-X Basic) offers a descriptive snapshot of bacterial diversity but is not a medical diagnostic tool. Combining IgG results with microbiome data may create a false sense of precision. For gut health, evidence-based approaches include symptom tracking, validated breath tests, and supervised elimination diets. IgG tests are primarily marketing-driven and lack clinical utility for gut health.
