Read the gut.
Then change it.

Comprehensive microbiome sequencing with clinical interpretation. Identify imbalances, design a personalised protocol, and retest to confirm what worked — guided by a GMC-registered clinician from sample to follow-up.

The science behind the test

Why method matters.

16S sequencing — what most labs use — only identifies bacteria at the genus level. Like knowing someone's surname but not their first name.

Different strains behave completely differently.

We use shotgun metagenomic sequencing for research-grade analysis. Every organism identified to species and strain — plus functional genes that show what the bacteria are actually doing, not just what they are.

For founders and biohackers: we provide raw FASTQ data, relative abundance CSVs and API access. Build your own analysis. Track interventions. Actually understand what's changing.

Frequently Asked Questions

Our comprehensive gut microbiome test starts from £350, which includes the home collection kit, laboratory analysis, detailed report, and a follow-up consultation to discuss your results and personalized treatment plan.

A gut microbiome test analyzes the bacteria, fungi, and other microorganisms living in your digestive tract. Using a stool sample, we identify the composition of your gut flora, detect imbalances, and assess markers of digestive health, inflammation, and nutrient absorption.

Results are typically available within 2-3 weeks. You will receive a comprehensive report detailing your gut bacteria composition, any imbalances detected, and personalized recommendations for improving your gut health.

Yes. Gut microbiome testing can identify specific bacterial imbalances and markers that contribute to IBS symptoms. This allows for targeted treatment including dietary changes, probiotics, and sometimes medication to restore healthy gut function.

Minimal preparation is required. We recommend continuing your normal diet for at least 2 weeks before testing. Avoid antibiotics for 4 weeks before the test if possible. You will receive a home collection kit with full instructions.

We send you a discreet home collection kit with clear instructions. The kit includes everything you need to collect a small stool sample hygienically. You then return the sample in the prepaid packaging provided. The process is simple and private.

Our test can identify bacterial imbalances, markers of inflammation, digestive enzyme function, presence of harmful bacteria or parasites, and how well you absorb nutrients. This information helps diagnose conditions like IBS, SIBO, and food intolerances.

If you have digestive issues, unexplained fatigue, skin problems, or autoimmune concerns, gut testing can provide valuable insights. Many patients find it helps identify root causes that standard tests miss, leading to more effective treatment.

No referral is needed. You can book directly with us online. Our doctors will review your results and provide personalized recommendations.

NHS typically offers basic stool tests for infections. Our comprehensive microbiome analysis examines hundreds of bacterial species and provides detailed insights that standard NHS tests do not cover.
