An at-home stool test analysing 10 markers of gut bacteria composition, including fibre-digesting and probiotic bacteria, for people wanting a general picture of their gut microbiome balance.
10 biomarkers as listed by Randox Health.
The Gut Microbiome Test analyses a stool sample for 10 markers of bacterial and viral composition, including bacteria that break down fibre, bacteria with probiotic properties, pathogenic bacteria, butyric-acid-producing bacteria and the Firmicutes/Bacteroidetes ratio. These markers are commonly used to build a general picture of gut bacterial balance, which can relate to digestion, though the test does not diagnose any specific digestive condition.
Against the 8 tests in its comparison group, its 10 markers sit well below the median of 24, which holds back its clinical depth score even though the test is broader than budget options like Selph's £129 Gut Bacteria, Worm and Parasite Test, which covers 7 markers. Selph's own Advanced version, at £249, covers 24 markers, more than double what this test measures.
It is priced close to the £228.50 group median, around 9% below it, sitting between cheaper options such as YorkTest's £199 Gut Microbiome Test and pricier ones such as Blue Horizon Medicals' £299 Oral Microbiome Test or Forth's £395 Gut Microbiome Test. The listing scores well for clarity and documentation, setting out the markers tested, sample type and turnaround clearly, though it does not describe what the results report looks like. Results and follow-up scores low because results are not reviewed by a doctor as standard, while trust signals remain high on Randox Health's Trustpilot rating, lab accreditation and CQC registration.
This may suit you if you want a moderate stool-based snapshot of your gut bacteria balance without needing the widest possible marker panel, and you are comfortable waiting up to 6 weeks for results. It sits in the middle of the market on price.
If marker count matters more than price to you, Selph's Advanced Gut Bacteria, Worm and Parasite Test covers 24 markers for £249, considerably more depth than this test's 10 markers. If a lower price matters more, Selph's standard version covers 7 markers for £129.
You collect a stool sample at home using the kit provided and post it to the lab, where it is analysed for 10 markers of bacterial and viral composition. Results are provided within 4 to 6 weeks of the sample arriving at the lab and are not reviewed by a doctor as standard.
This stool test looks at 10 markers of gut bacterial and viral composition, including fibre-digesting bacteria, probiotic bacteria and the Firmicutes/Bacteroidetes ratio. At £208 it sits close to the median for its comparison group, though its 10 markers are fewer than the group's median of 24, and results are not reviewed by a doctor as standard.
The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.

Cheaper, narrower screen than Selph's Advanced version
A 7-marker stool test screening for common gut bacteria and parasites by PCR and microscopy, for people with gut symptoms who want a lower-cost first check before considering a wider panel.
Broad pathogen panel priced near the market median
A 24-marker stool test covering a wide panel of bacterial, viral and parasitic gut pathogens by PCR, plus microscopy for ova, cysts and parasites, for people investigating persistent gut symptoms.
Deep 33-marker oral microbiome test, priced above peers
This saliva test analyses the bacteria living in your mouth, covering 33 markers of oral microbiome balance. It suits people interested in oral and general health via their microbiome rather than blood-based screening.
At-home vaginal microbiome test with a 25-day turnaround
An at-home swab test that profiles vaginal bacteria and yeast species, including several Lactobacillus and Candida species, plus pH. Suited to women wanting a detailed look at their vaginal microbiome rather than a quick screen for a single infection.
Mid-priced gut microbiome test, 18% below the group median
Analyses a stool sample using qPCR and 16S rRNA sequencing to profile the balance of bacterial and archaeal species in your gut, with a report broken into sections such as diversity and short-chain fatty acid scores.
DNA gut test that doesn't publish a biomarker count
An at-home stool test using DNA sequencing to analyse the gut microbiome. Suited to people with ongoing digestive symptoms such as bloating or changed bowel habits, or general curiosity about gut health.
Most expensive gut test in its comparison group
An at-home stool test analysing the gut microbiome, aimed at people with ongoing digestive symptoms such as bloating who want a broader look at gut bacteria than a standard stool test.
