wie teuer ist ein dna test — what are common causes?

The cost of a DNA test varies widely by provider and scope. Direct-to-consumer tests (e.g., MyBody-X, 23andMe) typically range from $50 to $300. However, price does not reflect clinical validity. Many tests screen hundreds of variants, but effect sizes are small and often poorly supported (e.g., FTO, TCF7L2). Evidence for genotype-based diet or exercise personalization is weak – RCTs show no clear benefit. More expensive tests with 'comprehensive' coaching are often marketing-driven. A DNA test can satisfy curiosity but should not replace medical evaluation. For specific health concerns (e.g., clotting risk), targeted clinical tests are more appropriate. Safety note: No direct health risk from testing, but potential for false reassurance or unnecessary worry.
