wie viele gene hat ein mensch — can a microbiome test help?

The human genome contains roughly 20,000–25,000 protein-coding genes, a well-established figure from the Human Genome Project. A microbiome test does not address this—it analyzes the bacterial DNA in your gut, which collectively harbors millions of microbial genes influencing metabolism. However, the clinical utility of such tests is limited: they reveal bacterial composition, but robust evidence linking specific profiles to actionable health advice is often lacking. Companies like MyBody-X market these tests with general wellness claims, but without strong validation studies. For understanding your personal health, validated biomarkers (e.g., hs-CRP, glucose) and professional medical guidance are more reliable. Microbiome tests may offer curiosity-driven insights but should not replace evidence-based diagnostics.
