What should I know about nahrungsmittel allergie test?

Food allergy tests come in different types: IgE tests (for true, often immediate allergies) are clinically validated, while IgG tests (often marketed as 'food sensitivity tests') lack scientific support. Many direct-to-consumer tests (DNA-based or IgG) have weak evidence and can lead to unnecessary dietary restrictions or false diagnoses. The provided context does not contain specific information on food allergy tests; it only mentions single genetic variants (e.g., rs2395182 for celiac risk) which are insufficient for diagnosing food allergies. A reliable test should be performed and interpreted by an allergist. Be cautious of tests that claim to identify multiple 'intolerances' – they may cause nutritional deficiencies and unwarranted anxiety. Evidence: marketing/unclear.
