Risks and limits of IgG Unverträglichkeit Kinder

IgG food intolerance tests in children lack scientific validation and are not recommended by medical societies (e.g., DGE, EAACI). A positive IgG result typically reflects normal immune exposure to food proteins, not intolerance. False positives can lead to unnecessary restrictive diets, nutritional deficiencies, and parental anxiety. In children, the risk of impaired growth and development is particularly concerning. Instead of IgG tests, suspected intolerances should be evaluated through clinical history, food diaries, and supervised elimination diets. IgE tests are appropriate for suspected allergies. The evidence is clear: IgG testing for food intolerance has no proven clinical utility in pediatric populations.
