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.
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.
