Comprehensive microbiome analysis
Explore the bacteria, fungi, parasites, viruses and archaea identified within your sample, alongside microbial diversity and balance.
Discover what is happening inside your microbiome with comprehensive laboratory testing, a detailed personalised report and practical guidance to help you understand your results.
Your gut microbiome contains a huge amount of information. We turn that data into a clear picture of what is happening inside your gut, what deserves attention and practical steps you can consider next.
Explore the bacteria, fungi, parasites, viruses and archaea identified within your sample, alongside microbial diversity and balance.
Rather than leaving you with raw laboratory data, your findings are translated into a detailed, understandable report with the important areas clearly explained.
Use your individual microbiome profile to inform personalised dietary and lifestyle recommendations rather than relying on one-size-fits-all advice.
Testing is supported by gut health practitioners who can help put your results into context and make the information more useful.
A microbiome test can produce a large amount of laboratory data. The important part is understanding what that information means for your individual gut.
The Complete Gut Microbiome Test looks beyond a simple list of bacteria to build a broader picture of your microbial ecosystem and digestive function.
Explore the variety and relative balance of microorganisms identified in your sample. This can help build a clearer picture of how your individual gut ecosystem is composed.
The analysis identifies important bacterial groups and can highlight where particular organisms appear relatively high, low or out of balance within your microbiome profile.
Advanced analysis can identify fungi, yeast, parasites, pathogenic bacteria, viruses and archaea, providing a more comprehensive view than bacteria alone.
Your report can include functional insights relating to microbial activity, nutrient absorption, metabolic processes and other markers that help put your microbiome profile into context.
Gut microbiome testing provides information about microbial composition and associated markers. It is not a medical diagnosis and should not replace advice from your GP or another qualified medical professional.
Your test is designed to be completed from home, with straightforward collection instructions and support throughout the process.
Choose your Gut Microbiome Test and we will send the collection kit directly to you.
Follow the enclosed instructions and take the required stool sample privately in your own home.
Your returned sample is analysed to build a detailed picture of the microorganisms and relevant markers found within it.
Your findings are turned into an understandable report, together with personalised recommendations based on your microbiome profile.
Children's microbiomes develop rapidly during the early years of life. Our children's testing provides parents with a detailed view of their child's microbiome using a simple at-home sample and personalised reporting.

People choose microbiome testing for different reasons. Some are trying to better understand persistent digestive symptoms, while others simply want more information about their gut microbiome and dietary habits.
A gut health test analyses a stool sample to provide information about microorganisms living within the digestive tract. Collectively, these microorganisms are known as the gut microbiome.
The gut microbiome contains bacteria alongside other microorganisms such as fungi, viruses and archaea. Its composition varies considerably between people and can also change over time.
Modern microbiome analysis can identify microbial DNA in a stool sample and estimate the microorganisms that are present. Depending on the laboratory and test panel, analysis may also provide information about microbial diversity, relative abundance and selected functional markers.
This is different from testing for one specific medical condition. A microbiome profile is better understood as a detailed snapshot of the microbial ecosystem present in your sample at that point in time.
Microbiome reports can contain a substantial amount of technical data. Interpretation helps place those findings into context and explain which parts of the report may be most relevant to diet, lifestyle and digestive wellbeing.
Learn how microbiome testing worksLaboratory testing can provide detailed information about the microorganisms detected in a stool sample, but understanding what the results do and do not mean is equally important.
Microbiome testing uses molecular laboratory methods to examine microbial material present in a sample. The quality of the result can depend on sample collection, laboratory processing, sequencing methodology and the bioinformatic methods used to interpret the data.
Using an established laboratory and following the sample instructions carefully therefore matters.
A microbiome result should be viewed as a snapshot rather than a permanent description of your gut. Diet, medication, illness, travel and other factors may influence microbial composition over time.
Changes between samples do not automatically indicate that something is medically wrong or that a treatment is required.
Although both may involve providing a stool sample, a private microbiome profile and an NHS stool investigation usually serve different purposes.
| Feature | Private Gut Microbiome Test | NHS Stool Testing |
|---|---|---|
| Primary purpose | Explore microbiome composition, diversity and selected microbial or functional markers. | Investigate specific symptoms or clinical concerns when medically indicated. |
| How it starts | Usually ordered directly by the individual. | Usually requested as part of assessment by a GP or another healthcare professional. |
| Type of information | Microbial profile and interpretation relating to the supplied test panel. | May test for infection, inflammation or other specific conditions depending on the investigation. |
| Diagnosis | Does not diagnose or rule out disease. | May form part of an established diagnostic pathway. |
| Sample | At-home stool collection. | Stool samples are often collected at home and returned according to NHS instructions. |
NHS stool testing is used as part of clinical investigations for specific symptoms and conditions. A private gut microbiome test should not be used as a replacement for NHS diagnostic testing or medical assessment.

Our Gut Microbiome Test costs £400, including free UK delivery. Our Babies, Infants and Children Gut Microbiome Test also costs £400. Food Intolerance 130 costs £230 and Food Intolerance 270 costs £280.
A small stool sample is collected at home using the instructions and collection materials supplied in your test kit. The sample is then returned for laboratory analysis.
No. A commercial microbiome test can provide information about the microorganisms and markers detected in your sample, but it does not diagnose IBS, inflammatory bowel disease or another medical condition. Speak to your GP if you need medical assessment of digestive symptoms.
NHS stool tests are generally used to investigate specific medical concerns such as infection, inflammation or other digestive conditions when clinically indicated. This is different from a private microbiome profile, which focuses on microbial composition and related insights.
Our microbiome tests use a stool sample to analyse microorganisms and gut-related markers. Our Food Intolerance 130 and 270 products use a finger-prick blood sample to measure IgG antibody responses to selected foods. They are different types of test and measure different things.
No. Our food panels report IgG antibody responses and should not be used to diagnose a food allergy. Food allergies can involve potentially serious reactions and require appropriate medical assessment. The clinical usefulness of IgG testing for identifying food intolerance is also debated, so results should be interpreted cautiously and should not be used alone to make major dietary changes.
Yes. We offer microbiome testing specifically for babies, infants and children. The test uses a non-invasive stool sample collected at home. Check the product information for guidance appropriate to your child's age.
