was sind gene — can a microbiome test help?

Genes are the fundamental units of heredity, encoded in DNA, that provide instructions for making proteins. A microbiome test analyzes the composition of gut bacteria, not human genes. Such tests can offer insights into microbial diversity and potential imbalances, but they do not diagnose diseases. The evidence for actionable recommendations from microbiome tests is often weak, based on correlations rather than causation. Many consumer tests overstate their clinical relevance. A microbiome test can be useful as part of a holistic health approach, but it should not replace medical advice. For specific health concerns, consult a healthcare professional.
