was kostet dna analyse — can a DNA test help?

The cost of a DNA analysis varies widely depending on the provider and scope: direct-to-consumer (DTC) tests like 23andMe or MyBody-X typically range from €50 to €200, while comprehensive clinical analyses can cost several hundred euros. Whether a DNA test can help depends on the question. For medically relevant genes (e.g., APOE ε4, MC1R), DTC tests provide risk indications but not diagnoses. The evidence is often moderate: APOE ε4 increases Alzheimer's risk, but most carriers never develop the disease. For performance genes like ACTN3, predictive power is low and often overhyped. Polygenic scores for metabolism or fitness are not clinically validated and vary by ancestry. A test can help if you have realistic expectations and discuss results with a doctor. Testing children is not recommended as it may cause anxiety without proven preventive options. Bottom line: DNA tests offer interesting insights but no reliable action plans. Weigh the cost against the limited utility.
