was kostet ein gen test — what can you do yourself?

The cost of a genetic test varies widely: direct-to-consumer (DTC) tests like 23andMe or MyHeritage range from about €50–150, while comprehensive clinical tests (e.g., exome sequencing) can cost several hundred to thousands of euros. What you can do yourself: order a kit, collect a saliva sample, and mail it in. Raw data is often provided, but interpreting it is complex. The provided context lacks specific pricing or DIY instructions. Many tests (e.g., for APOC3, FUT2, FTO) show only small effect sizes or are not validated for self-diagnosis. Without medical guidance, you risk misinterpretation or unnecessary anxiety. Especially for pharmacogenetics (e.g., TPMT before azathioprine), professional evaluation is critical. Bottom line: sample collection is DIY-friendly, but analysis and clinical decisions require expert oversight.
