Comprehensive gut health & microbiome testing
Our testing suite combines the most advanced diagnostics with expert clinical interpretation to give you a full view of your gut microbiome, digestive function and overall gut health - with results you can act on
Stool microbiome analysis
Identifies the diversity and balance of gut bacteria and other microorganisms, as well as looking for signs of inflammation, infection and other markers
Hydrogen sulphide & other breath testing
Detects bacterial overgrowth and certain food intolerances, for diarrhoea or bloating linked to specific bacteria.
Gut permeability (“leaky gut”) assessments
Checks the integrity and functioning of your gut lining.
SIBO testing
Identifies bacterial overgrowth in the small intestine.
Gastric acid output test
For low stomach acid or hypochlorhydria.
Gut motility and transit studies
Measures how quickly food moves through your system.
What makes us different: A new standard in gut health support
“Your gut microbiome (the trillions of bacteria and other microorganisms living in your digestive tract) plays a central role in digestion, immunity, energy production and even mental health. When it’s diverse and well-balanced, it can cut your disease risk, increase performance and support your overall wellbeing. When it’s disrupted, it can contribute to a wide range of symptoms and health conditions.
The challenge is that most microbiome tests leave you with reams of data but no clear path forward.
Our Microbiome Clinic is different. We deliver results you can act on, with expert support to help you make changes that matter.”
Prof Anthony Hobson
Founder of The Functional Gut Clinic

Microbiome Clinic FAQ
Do I need to have symptoms to benefit from the Microbiome Clinic?
No, not at all. While many people come to us with gut symptoms they want to get to the bottom of, others simply want to understand and optimise their gut health as part of a proactive approach to wellbeing. Whether you're dealing with bloating, IBS or fatigue, or just curious about your microbiome, our tests offer valuable insights.
What happens after my testing?
Once your test results are ready, you’ll receive clear, easy-to-understand results, along with treatment guidance based on your results. This may include evidence-based information around diet, lifestyle and supplements. Depending on your results, we may also discuss more advanced treatment options suitable for you.
If your results indicate that further clinical input is needed, we can arrange a consultation with one of our expert clinicians. This may include a neurogastroenterologist (specialising in gut-brain connection, hypnotherapy, gut-focused yoga), a consultant gastroenterologist, or a GP for further treatment options.
Is FMT available through the Microbiome Clinic?
FMT (or IMT, intestinal microbiota transplant) is currently available under specific regulatory conditions as a "specials" treatment. You can read more about FMT on our blog here, or get in touch to discuss your options with us.
Do PPIs affect the microbiome?
There is growing evidence that long-term use of proton pump inhibitors (PPIs), such as omeprazole or lansoprazole, may alter the balance of your gut bacteria. If you're taking these medications, we recommend discussing this as part of your assessment.
Is constipation associated with changing the microbiome?
Research shows that changes in bowel habits, including constipation, can be linked to alterations in the gut microbiome. In some cases, reduced microbial diversity or imbalances may contribute to symptoms like sluggish transit or bloating. Our testing can help assess whether your microbiome may be playing a role in your symptoms.
Can I get involved in research?
Yes - we regularly run clinical trials and gut health studies at the Functional Gut Clinic. If you'd like to be part of our groundbreaking research, you can find the latest trials we're recruiting for here and sign up to be the first to hear about upcoming opportunities.
I'm a company interested in microbiome research and clinical trials - what are my options?
We work with gut health companies, healthcare brands, universities and product developers to design and deliver credible clinical trials in the microbiome space and beyond. If you’re looking to generate high-quality evidence to evaluate and support your product, supplement, or gut health intervention, we’d love to hear from you.
