was kostet ein gentest — can a microbiome test help?

The cost of a genetic test ranges from about €50 for raw data (e.g., 23andMe) to €200–500 for comprehensive health reports with counseling. Microbiome tests (stool analysis) typically cost €100–300. Can a microbiome test help? It provides a snapshot of gut bacteria composition, but clinical utility is limited. For example, the FUT2 variant (rs601338) influences Bifidobacterium colonization – a genetic test can indicate this, while a microbiome test directly measures the bacteria. However, no official guidelines recommend specific interventions based on such tests. For children with low Bifidobacteria, current practice advises against probiotics solely from test results. The main value is dietary awareness (e.g., fiber intake), not diagnosis. Be cautious of marketing claims that overstate actionable insights. Evidence is mixed: mechanistic for FUT2, but lacking strong clinical studies for routine microbiome testing benefits.
