Common mistakes around IgG Unverträglichkeit Kinder

Common mistakes around IgG intolerance testing in children: First, IgG is often misinterpreted as an allergy marker – in reality, it reflects normal immune exposure, not intolerance. Second, these tests lack clinical validation; many measure IgG4, which is associated with tolerance rather than adverse reactions. Third, false positives lead to unnecessary dietary restrictions, risking nutritional deficiencies in growing children. Fourth, parents may use home tests without medical guidance, overlooking underlying conditions like infections or functional disorders. Fifth, evidence for IgG-guided elimination diets is weak; major allergy organizations (e.g., EAACI) do not recommend them. A proper diagnosis requires a physician-supervised process including symptom diary, elimination diet, and controlled challenge.
