How we combine them
We don't copy anyone's summary numbers. We recount from the per-sample data ourselves, so every share and comparison on the site comes from the same
samples and the same method. Evidence stays separate per source: when a genome says one thing and a lab test another, we show both and say so, rather
than blending them into one answer. Nothing here is a measurement of your own gut.
How strong a finding is, when it's shown and how it's worded follow one public rulebook. Read the rules →
Microbes and guts GMrepo v3
Updated Oct 14, 2026 Which microbes are found in healthy and sick guts, and how often: the samples behind every share and comparison, which we recount ourselves. “Our analysis of GMrepo data” on a page means this.
