was kostet ein gentest — what can you do yourself?

The cost of a genetic test varies widely by provider and scope. A lifestyle DNA test like MyBody-X Longevity typically ranges from €100 to €300. What you can do yourself: order the kit online, collect a saliva sample at home, and mail it to the lab. Results are delivered via app or online portal with personalized recommendations for diet, exercise, and skincare. Important: these tests are not diagnostic – they do not replace a doctor. You can view your own data, but interpretation should be critical. Many claims, such as diet-type labels based on FTO or MC4R, have weak scientific support (see context: PMID:26888713). In Germany, the Genetic Diagnostics Act (GenDG) restricts testing for minors without medical benefit. So the DIY part is limited to sample collection and result access – the actual analysis and advice require caution. For medical concerns, consult a clinical geneticist. Overall, you can perform the test yourself, but the evidence behind many recommendations is thin, and marketing often overshadows science.
