Analyse Booklet | Testergebnisse in Buchform: can a DNA test help?

A DNA test can provide insights into genetic predispositions, e.g., for diet or exercise, but it is not a diagnostic tool. Results presented in a booklet format are often simplified and marketing-driven. For concrete health decisions, medical advice should be sought. The evidence is mixed: GWAS studies show weak associations, but clinical guidelines (e.g., ACMG/CDC) advise against direct-to-consumer DNA testing for many variants. A microbiome test can flag imbalances, but a universal definition of a 'healthy' microbiome is lacking. Caution is needed for children or pregnancy: the tests are not validated. Overall, DNA tests can serve as a general health guide, but not as a clinical tool.
