Is DNA Stoffwechseltest useful for Allergie?

A DNA metabolism test (e.g., MyBody-X) is not scientifically validated for allergy diagnosis or management. Allergies are immune-mediated (IgE), while metabolism tests focus on enzyme variants (e.g., LCT, MTHFR). Some genetic variants (e.g., HLA-DQ2/DQ8) can indicate celiac disease risk, but that is an autoimmune condition, not a classic allergy. Evidence for direct allergy prediction from metabolism genes is weak to nonexistent. Such tests are marketed as screening or lifestyle tools, not medical diagnostics. If you suspect allergies, consult an allergist for proper testing (skin prick, specific IgE). Dietary changes based solely on DNA results may lead to unnecessary restrictions or nutrient deficiencies. Conclusion: The test is not useful for allergies in an evidence-based sense.
