What to watch with DNA Stoffwechseltest and allergy?

When considering a DNA metabolism test that claims to address allergies, caution is warranted. The evidence base is generally weak: most genetic variants tested (e.g., in GST genes like GSTM1) have small effect sizes and come from observational studies, not randomized trials. Allergies are highly multifactorial – environment, microbiome, diet, and immune status are far more influential than single genes. A DNA test cannot reliably predict allergy risk or triggers. Marketing claims of personalized allergy prevention through such tests should be viewed skeptically. A more evidence-based approach combines clinical diagnostics (e.g., skin prick tests, IgE measurements) with dietary tracking. The test may offer only marginal, probabilistic hints and should never replace medical evaluation.
