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.
7 biomarkers as listed by Selph.
The Gut Bacteria, Worm and Parasite Test screens for five common bacterial and parasitic causes of gut infection by PCR (Campylobacter, Giardia, Salmonella, STEC and Shigella), plus Cryptosporidium PCR and stool microscopy for ova, cysts and parasites, which can pick up worms not covered by the PCR panel.
Against the eight gut microbiome tests we track, its 7 markers sit well below the median of 24, but its £129 price is about 44% below the £228.50 median, making it the cheaper, narrower option in the group. Selph's own Advanced Gut Bacteria, Worm and Parasite Test extends the same core panel to 24 markers for £249, adding a much longer list of viral and bacterial PCR targets.
This is why it scores very highly on value for money but only moderately on Clinical Depth relative to its comparison group. Collection Convenience is middling, reflecting a stool-only collection method and a turnaround of around 6 days.
This suits you if you want a lower-cost first check for the most common bacterial and parasitic causes of gut symptoms, particularly after travel or suspected food poisoning. If your symptoms persist after a negative result, or you want broader coverage of viral and other bacterial causes from the outset, Selph's Advanced Gut Bacteria, Worm and Parasite Test covers 24 markers for £249.
You collect a stool sample at home and post it to the lab; there is no clinic or blood-based alternative for this test. A Selph doctor reviews the PCR and microscopy results and provides a written report, typically within 5 to 6 days.
