Risks and limits of IgE Allergie Ernährung

IgE tests (specific immunoglobulin E) indicate sensitization to allergens, but not necessarily clinical allergy. A positive IgE result does not guarantee symptoms – many individuals have elevated IgE without any reaction. Conversely, a negative test does not rule out allergy. Relying solely on IgE results for dietary changes carries risks: unnecessary food avoidance can lead to malnutrition, especially in children. IgE levels can fluctuate, and false positives are common. Evidence from observational studies and reviews shows that IgE tests should only be interpreted together with a clinical history and, if needed, challenge tests. For allergy-related nutrition therapy, medical evaluation is essential. MyBody-X tests are screening tools, not diagnostic. Limitations: no information on severity or tolerance threshold. Risks: overdiagnosis, unnecessary diets, psychological burden. Recommendation: consult an allergist if symptoms are present.
