was kostet ein gen test — what are common causes?

The cost of a genetic test varies widely: simple direct-to-consumer (DTC) tests start around €50, while comprehensive analyses with physician counseling can cost several hundred euros. Common reasons for testing include ancestry, health risk assessment (e.g., BRCA, APOE), nutrigenetics (e.g., FTO, MTHFR), sports genetics (e.g., ACTN3), and carrier screening for inherited conditions. However, many DTC tests provide only statistical risk estimates, not diagnoses. The evidence for clinical utility of many SNPs is weak (e.g., FTO effect <0.5 kg/m²). Without professional interpretation, results can lead to false reassurance or unnecessary anxiety. Costs are rarely reimbursed, and test quality varies. Pre- and post-test counseling is strongly advised.
