Risks and limits of Stuhlprobe Test

Stool tests (e.g., microbiome analysis) as consumer self-tests have significant limitations: lack of validated reference ranges for most markers, no proven clinical utility for healthy individuals, and a tendency toward overinterpretation. Many providers rely on marketing rather than evidence. Risks include unnecessary anxiety, inappropriate dietary changes, and wasted money. For medical diagnostics (e.g., fecal occult blood, pathogen detection), stool tests are well-established. Consumers should be cautious of tests claiming to assess 'gut health' without transparent validation. Evidence grade: marketing/unclear.
