was kostet ein gentest beim mensch — can a DNA test help?

The cost of a human genetic test varies widely: direct-to-consumer (DTC) tests like 23andMe or MyBody-X typically range from €100 to €300, while clinical-grade tests (e.g., exome sequencing) can cost several thousand euros. Whether a DNA test can help depends on the goal. For pharmacogenetics (e.g., SLCO1B1 variant rs4149056 for statin myopathy risk) there is moderate evidence, but DTC reports often oversimplify and are not suitable for treatment decisions. Many offered tests (e.g., food intolerance) rely on marketing rather than clinical validation. A DNA test can be useful for a clear question with medical interpretation, but results are rarely deterministic. Evidence is mixed: strong for some pharmacogenetic markers, weak for most lifestyle claims. Beware of exaggerated promises.
