Who lives in your gut
Bacteria, viruses, fungi and protozoans, identified to species and, where possible, strain level.

Microbiome test from one stool sample
Reads all the DNA in your stool sample: which microorganisms live in your gut, what they can produce and how they connect to digestion, immunity, metabolism and wellbeing. Also includes an analysis of human genetic variants found in the sample.
€340 · one-time payment
Collection kit, sequencing and full report included.
Three layers of insight, in one report.
Bacteria, viruses, fungi and protozoans, identified to species and, where possible, strain level.
Your microbiome's capacity to produce butyrate, B vitamins, GABA and other compounds your body relies on.
Links between your microbiome and digestion, immunity, metabolism, hormones and the nervous system, with explained scores.
One stool sample, with simple collection and return instructions.
Sequencing of all DNA in the sample: microbiome and human DNA.
Summary, tables, charts, reference ranges, explanations and scientific sources.
Clear findings organised by topic, ready to bring to your appointment.
Analysis scope
What each chapter shows, in plain language.
Shotgun metagenomics
Most microbiome tests read a single region, the 16S gene, which only bacteria carry. We sequence all the DNA in the sample: bacteria, viruses, fungi and your own DNA. That is how we see organisms and functions a 16S test cannot detect.
The DNA is broken into fragments and each is read separately — like a puzzle of millions of pieces. This reaches genes, not just species.
Each sample produces millions of reads, enough for fine identification down to strain level.
Every fragment is matched against known genomes and genes in up-to-date reference databases.
All of this detail has one purpose: to show the relationship between your microbiome and your body. The microorganisms in your gut produce compounds that influence digestion, immunity, mood and metabolism. The report translates what happens in the gut into concrete findings you can discuss with your doctor.
