wie teuer ist ein dna test — when to see a doctor?

The cost of a DNA test varies widely: ancestry-only tests are around $50–100, while comprehensive health or nutrigenetic panels (like MyBody-X) range from $150 to $500. These tests are not diagnostic; they provide risk estimates and genetic insights. When to see a doctor: if you receive results indicating elevated disease risk, pharmacogenetic variants (e.g., TPMT, CYP2D6), or if you have existing health concerns. A physician can interpret results in clinical context, order confirmatory lab tests, and guide treatment or lifestyle changes. Self-interpretation may lead to unnecessary anxiety or inappropriate actions. Evidence for many direct-to-consumer tests is marketing-based; only a few markers (e.g., TPMT, CYP2D6) have strong clinical guidelines (CPIC). Always consult a doctor before making medical decisions based on DNA test results.
