Questions people ask about IgG Unverträglichkeit Basis

Questions about IgG food intolerance tests (often marketed as 'IgG Basis' or 'IgG food sensitivity') are common but scientifically controversial. IgG antibodies to foods are a normal immune response to dietary exposure and do not reliably indicate intolerance or allergy. Major medical guidelines (e.g., from the German Society for Allergology and Clinical Immunology) advise against using IgG tests for diagnosis, as they lack clinical validity and reproducibility. The evidence is primarily marketing-driven; no high-quality studies show consistent symptom improvement from diets based on IgG results. False positives can lead to unnecessary dietary restrictions, nutritional deficiencies, and anxiety. For suspected food intolerances (e.g., lactose, fructose, histamine), validated methods like breath tests or medically supervised elimination diets are recommended. MyBody-X does not offer IgG testing; the products referenced here focus on microbiome or DNA analysis for different purposes.
