was kostet ein gentest herkunft — what does this mean exactly?

The question 'what does a genetic ancestry test cost?' is straightforward, but the answer depends on provider and scope. Typical direct-to-consumer (DTC) tests like 23andMe, AncestryDNA, or MyHeritage range from €50 to €200, often with discounts. These tests analyze hundreds of thousands of SNPs and compare them to reference populations. The results are estimates, not absolute certainty. Accuracy varies by ethnicity – for mixed or non-European backgrounds, estimates are less reliable. These tests do not provide medical information unless you choose a health+ancestry bundle. Basic ancestry tests are usually under €100, but consider data privacy risks. Evidence for reliability is moderate (many GWAS studies, but population-dependent).
