Most stool tests tell you what’s going wrong. Very few tell you what’s missing.

The Microbiome Explorer Comprehensive is the only stool test we offer that maps the 200+ beneficial bacteria that make up your healthy gut community — the ones most tests don’t even look for. While standard gut tests focus narrowly on pathogens or a handful of inflammation markers, this test reveals the full picture: what’s thriving, what’s depleted, what’s producing harmful compounds, and what’s driving your symptoms at a root cause level.

If you’ve had gut tests before and been told everything looks normal, this is likely the test you’ve been missing.

The Microbiome Explorer Comprehensive stands apart from most stool tests because it uses metagenomic sequencing — the same technology used in cutting-edge microbiome research — rather than the older PCR or culture-based methods that can only detect what they’ve been specifically programmed to look for. While a standard stool test might screen for a dozen or so pathogens and call it done, this test maps your entire gut ecosystem across 200+ beneficial bacterial species, assessing not just presence but function — what those microbes are actually producing and how they’re influencing your health. It also combines three technologies in a single sample: full microbiome ecosystem mapping, a seven-marker gut physiology panel covering inflammation, immune defence, and intestinal permeability, plus an 18-target pathogen and parasite screen. The result is 40 validated biomarkers from one collection, benchmarked against a healthy reference range, with an expert summary written by microbiome specialists — a level of clinical depth that no other stool test currently available in the UK comes close to matching.
