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.
The Gut Microbiome Test uses DNA sequencing on an at-home stool sample to analyse the microorganisms living in your gut, which are commonly linked to digestion, immunity and metabolism. YorkTest positions it for people with ongoing digestive symptoms such as bloating, discomfort or changed bowel habits, as well as those wanting to understand their gut health better.
Within its gut microbiome comparison group, its £199 price sits 13% below the £228.50 median, cheaper than Randox Health's Gut Microbiome Test at £208 and Blue Horizon Medicals' Oral Microbiome Test at £299, but more expensive than Selph's Gut Bacteria, Worm and Parasite Test at £129 and Blue Horizon Medicals' own Gut Microbiome test at £186.25.
Its Clinical depth score is low, because unlike Selph's tests, which list a specific marker count, YorkTest does not state how many organisms or markers its report covers, so depth can't be properly assessed. It scores well for Trust signals, reflecting YorkTest's Trustpilot rating of 4.8 from 3,257 reviews, its UKAS-accredited lab, and 44 years of trading. It scores lower for Results and follow-up, and its overall confidence score is reduced slightly because of the missing marker count.
This suits people with ongoing digestive symptoms, or general curiosity about their gut health, who are comfortable providing a stool sample rather than blood and waiting slightly longer than usual for results. Because YorkTest doesn't publish a marker count, it's hard to compare depth directly against Selph's Gut Bacteria, Worm and Parasite Test, which lists 7 named markers for £129, a lower price. If a stated marker count matters to you, check the specific report contents with YorkTest before ordering. It is not the right choice if you want a doctor to review your results as standard.
You collect a stool sample at home and return it to YorkTest's laboratory, where DNA sequencing is used to analyse the microorganisms present. Turnaround is longer than YorkTest's blood tests, at a stated 10 to 15 days. Results are not reviewed by a doctor as standard.
YorkTest's Gut Microbiome Test analyses the gut microbiome from an at-home stool sample using DNA sequencing, for £199, 13% below the £228.50 median for its comparison group. Unlike some peers, the provider does not state how many organisms or markers the report covers. Turnaround is longer than most YorkTest tests, at 10 to 15 days, and results are not reviewed by a doctor as standard.
The listing publishes a short description, a stated turnaround, clear collection options, the sample type; it does not state the biomarkers measured, what the report looks like.
The provider does not state how many biomarkers are measured, so depth cannot be assessed.
A stool sample you take at home, no needle; results in around 15 days, slower than similar tests.
Results are not doctor-reviewed and no consultation is included; the provider does not describe the report format.
Trustpilot 4.8 from 3,257 reviews; accredited lab (UKAS accredited own lab (ISO 13485)); trading 44+ years.

This test belongs to our Gut microbiome test comparison group. See how it stacks up against equivalent tests from other providers.
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.
Mid-priced gut microbiome test, fewer markers than peers
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.
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.
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.
