wieviel kostet ein dna test — can a DNA test help?

The cost of a DNA test varies widely depending on the provider, scope, and quality. Simple ancestry or single-variant tests (e.g., MTHFR) can cost between €50 and €150. More comprehensive health or metabolism analyses, like those from MyBody-X, typically range from €150 to €400. However, the evidence for many direct-to-consumer (DTC) DNA tests is limited. Studies show that genotype-based diet recommendations (e.g., for FTO variants) offer no advantage over general dietary advice (PMID: 37813841). Polygenic risk scores are also less accurate for non-European ancestries (PMID: 36477530). A DNA test can provide interesting insights, but it does not replace medical diagnosis. For specific concerns (e.g., MTHFR and folate), consulting a doctor is more valuable than a self-test. Bottom line: costs are moderate, but the actual benefit is often questionable. Invest in evidence-based medical advice instead.
