wie viel kostet ein dna-test in deutschland — what are common causes?

The cost of a DNA test in Germany varies widely depending on the provider and scope. Basic ancestry tests (e.g., MyHeritage, 23andMe) typically cost between €50 and €100, while comprehensive health and nutrigenetics panels (e.g., MyBody-X) can range from €150 to €400. Importantly, many direct-to-consumer tests are not certified as medical devices and do not provide clinically validated diagnoses. Common reasons for taking a DNA test include: ancestry research, personal health screening (e.g., risk variants for lactose intolerance, fat metabolism), sports and nutrition optimization (e.g., FADS1, PPARA), and pharmacogenetic insights (e.g., CYP1A2). However, the evidence for many of these markers is weak – mostly based on GWAS with small effect sizes. A test does not replace medical advice. Additional costs may arise for genetic counseling or follow-up blood tests. Consumers should be skeptical of exaggerated claims, especially for tests that purport to determine the 'ideal diet'. Actual predictive value is often limited and ancestry-dependent.
