was kostet ein gentest erbkrankheiten — what can you do yourself?

The cost of a genetic test for hereditary diseases varies widely depending on scope and provider. Direct-to-consumer (DTC) tests like 23andMe or MyHeritage typically range from €100 to €500, but they usually test only a limited set of risk variants and do not provide a full diagnosis. Clinical genetic tests ordered by a doctor can be more expensive (often several hundred to thousands of euros), but are frequently covered by health insurance if medically indicated. Important: DTC tests have limited predictive value for rare hereditary diseases – they cover only a few known mutations and can yield false positives or false negatives. What you can do yourself: 1) Collect your family history (cancer, cardiovascular, metabolic diseases). 2) Consult a genetic counselor or specialist if concerns arise. 3) Use test results as a hint, not a diagnosis. 4) Focus on a healthy lifestyle (diet, exercise, sleep), which can mitigate many genetic risks. 5) Seek comprehensive counseling before any genetic test. Without medical guidance, test results may cause unnecessary anxiety or false reassurance. Evidence for the benefit of DTC tests for hereditary diseases is weak (marketing/unclear), while clinical genetic testing with proper indication has strong evidence (human-strong).
