Can DNA Stoffwechseltest help with allergy?

A DNA metabolism test (e.g., MyBody-X) cannot predict or diagnose allergies. Allergies are complex, involving environmental triggers, immune responses, and many genes. Some variants (e.g., in FUT4) have been weakly associated with allergic conditions, but effect sizes are small and not clinically actionable. The test does not provide reliable information about your personal allergy risk or dietary needs. Evidence level: mixed/unclear. For allergy assessment, skin prick tests or specific IgE blood tests performed by a physician are the gold standard. Do not rely on consumer DNA tests for allergy guidance.
