wie teuer ist ein gentest — what does this mean exactly?

The cost of a genetic test varies widely depending on the type and provider. Direct-to-consumer (DTC) tests like 23andMe or MyHeritage typically range from $50 to $200, but they analyze only selected SNPs and are not diagnostic. Clinical genetic tests (e.g., for BRCA1/2) are more expensive, often $300–$2000, and require a physician's order. The meaning of a genetic test is nuanced: it reveals genetic variants, but most traits are polygenic and influenced by environment. Many DTC companies overstate the predictive power of single SNPs. A genetic test is not a destiny verdict but one piece of a larger puzzle. Without validated references from the provided context, the evidence level is unclear. Be cautious of marketing claims: a single SNP rarely determines skin aging or athletic performance directly.
