Evidence check: DNA Stoffwechseltest in the context of allergy

DNA metabolism tests (e.g., CYP1A2, CYP2D6) analyze enzymes that process drugs or dietary compounds. A direct link to allergies is not scientifically established. Allergies are primarily driven by immune reactions to allergens, involving genes like HNMT (histamine breakdown) or HLA complexes – which are not covered by typical metabolism tests. The provided context sources contain no studies connecting CYP1A2/metabolic genes to allergy risk. DTC providers often overstate clinical relevance. For allergies, established methods such as IgE testing, skin prick tests, and clinical history are essential. A DNA metabolism test may support personalized nutrition or medication choices but does not replace allergological workup. Evidence: unclear, as no direct human studies are in context.
