Myths vs facts: NutriCare | INFINITY DNA-Test and allergy

DNA tests like the NutriCare | INFINITY DNA-Test often claim to identify food intolerances or allergies. The scientific reality is sobering: true allergies are diagnosed via IgE antibodies or skin prick tests – not by genetic testing. While certain genetic variants (e.g., in HLA or filaggrin genes) are associated with a slightly increased allergy risk, the effect is small and insufficient for diagnosis. Many of the claims made by such tests rely on weak evidence (mechanistic or purely associative) and are often exaggerated for marketing. A DNA test cannot confirm or rule out an allergy. Anyone with real symptoms should see a doctor and undergo standard allergy testing. The risk is that people may unnecessarily avoid foods or take wrong supplements based on genetic results. In short: DNA tests for allergies are currently more of a lifestyle novelty than a medically valid tool. The evidence is mostly weak to marketing-driven.
