wo kann man dna test machen — what can you do yourself?

DNA tests for consumers are available as direct-to-consumer (DTC) kits online from companies like 23andMe, AncestryDNA, MyHeritage, or MyBody-X. You order a kit, collect a cheek swab or saliva sample at home, and mail it back. The analysis typically covers ancestry, some health risk variants, or traits. What you can do yourself: take the sample, return it, and view results online. However, these tests are not clinically validated and should not replace medical diagnosis. For serious health questions (e.g., BRCA genes), a doctor's order is required. The ACMG warns against overinterpretation. You can also download raw data and use third-party tools, but this carries risks. Evidence: practice (DTC market).
