Gut Microbiome Test
A comprehensive analysis of your gut microbiome that reveals the precise composition of bacteria, fungi and other microorganisms living in your digestive system, and how they are affecting your energy, immunity, skin health, mood and metabolic function.
What it is
A map of your gut, read in clinical context.
Your gut microbiome is one of the most powerful indicators of your overall health. An imbalanced microbiome has been clinically linked to chronic inflammation, digestive issues, weight gain, skin conditions, brain fog, poor immunity and hormonal disruption.
The test is a stool-based analysis using advanced sequencing technology to identify and quantify the microorganisms present in your gut. It goes far beyond standard digestive testing, mapping the diversity, balance and functionality of your microbiome at a level of detail standard NHS or GP tests do not provide.
Results are interpreted in the context of your full health picture (skin concerns, energy levels, inflammatory markers and lifestyle) by a GMC-registered consultant with expertise in the gut–skin–immune axis.
Conditions linked to microbiome imbalance
What dysbiosis looks like.
Acne, rosacea, eczema, psoriasis and chronic inflammation are all strongly associated with gut dysbiosis and increased intestinal permeability.
Skin conditionsBloating, IBS, irregular bowel habits, abdominal discomfort and food intolerances frequently trace back to microbiome imbalance.
Digestive symptomsPoor microbial diversity reduces the gut's ability to produce short-chain fatty acids and B vitamins, a key driver of persistent fatigue.
Fatigue & low energyThe gut produces over 90% of the body's serotonin. Dysbiosis is directly linked to low mood, anxiety, poor concentration and cognitive fatigue.
Mood & brain fogApproximately 70% of the immune system resides in the gut. Microbiome imbalance compromises immune function and increases susceptibility to illness.
Weakened immunitySpecific gut bacterial profiles influence how efficiently the body extracts energy from food, stores fat and regulates appetite hormones.
Weight & metabolism“There is strong clinical evidence linking gut dysbiosis to acne, rosacea, eczema and psoriasis. Where a skin condition resists topical treatment, this is often where the answer sits.”
What the test reveals
Nine layers of data.
Across 500+ species, the composition and evenness of your microbial ecosystem.
Gut inflammation markers and indicators of intestinal permeability.
Immune system activation and the state of gut-associated immunity.
Production levels and what they mean for your energy metabolism.
Probiotic species levels and beneficial bacteria ratios.
Pathogenic bacteria, parasites and fungal overgrowth.
Markers linked to mood and cognition.
Indicators relevant to inflammatory skin conditions.
Biomarkers relevant to weight regulation and metabolism.
Why choose this test here
Interpreted, not just reported.
Interpreted by a consultant
Unlike direct-to-consumer kits, your results are interpreted by a GMC-registered consultant dermatologist with specific expertise in the gut–skin–immune relationship, not an algorithm.
Joined to your skin plan
If you are also managing rosacea, acne, eczema or another skin condition at the clinic, microbiome findings are integrated into your overall treatment plan for a more complete, root-cause approach.
High-resolution analysis
The test profiles 500+ bacterial species, fungi, parasites and key metabolic markers, significantly more detailed than standard stool tests used in primary care settings.

It is a stool-based analysis that uses advanced DNA sequencing to identify and measure the microorganisms in your digestive system, including bacteria, fungi and parasites, and assess how they are influencing your health.
You receive a discreet at-home collection kit. A small stool sample is taken at home and returned to the laboratory via a prepaid courier. No clinic visit is required for sample collection.
Results are typically available within two to three weeks of the laboratory receiving your sample. A follow-up consultation with Dr Yoo is then scheduled to review findings and discuss your personalised plan.
The test is appropriate for most adults. It is particularly recommended for those with persistent digestive symptoms, skin conditions with a possible gut–skin link, chronic fatigue, recurrent illness, or those seeking a comprehensive longevity baseline.
Standard GP stool tests screen for specific pathogens or infections. The gut microbiome test uses metagenomic sequencing to map the entire microbial ecosystem, including balance, diversity, inflammation markers and metabolic output, at a level of detail not available through routine NHS testing.
Yes. There is strong clinical evidence linking gut dysbiosis to skin conditions including acne, rosacea, eczema and psoriasis via the gut–skin axis. Addressing microbiome imbalances can meaningfully support the management of these conditions alongside topical or laser treatments.
Dr Yoo reviews your results in a dedicated follow-up consultation and provides a personalised restoration plan covering diet, probiotic and prebiotic supplementation, lifestyle adjustments and any relevant clinical treatments at the clinic.
Yes, and this is often recommended. Gut microbiome testing works well alongside bespoke IV drip therapy, NAD+ therapy, personalised diet planning and skin treatments, particularly for patients managing inflammatory or condition-related skin concerns.
