What You Get — in Plain English

  • A complete breakdown of your ENTIRE gut microbiome — from 28,000+ species now identified
  • Detection of 18 disease causing pathogens (bacteria and parasites)
  • Gut integrity check (Is your gut “leaky”?)
  • Inflammation and faecal blood markers (potential medical red flags)
  • Digestive performance overview
  • Insights into your health-positive vs health-negative bacteria with real clinical impact
  • A personal roadmap to correct gut imbalances, reduce disease risk and boost well-being

“This test doesn’t just tell you what’s in your gut it tells you what it’s doing”

Why This Test Matters

This is not the same old stool test.


Traditional testing only shows a tiny part of your gut microbiome. This test shows the full picture and helps uncover the why behind symptoms. We know 90% of disease starts in the gut and now we can understand the why.

Whether you're dealing with:

Long-term or chronic gut problems
Ongoing fatigue or brain fog
Skin conditions like eczema
Asthma and migraines
Bloating or IBS type symptoms
Autoimmune flares
Weight struggles...

This test gives you specific, actionable answers.

Who This Test Is For

This is for you if:

  • You’re tired of not getting answers about your symptoms
  • You want to take proactive control of your long-term health
  • You’re looking for accurate, science-backed insights from a qualified professional

What Makes This Test Different

Next-Generation Metagenomic Sequencing

  • Most accurate technology on the market
  • Entire microbiome sequenced — species-level precision
  • Mapped against a large healthy cohort (chosen from 12,000 adults)

Exclusively from Co-Biome Australia and only available in the UK via Invivo Practitioners

Delivered with Expert Interpretation

You'll receive a personalised consultation and results masterclass with me with expert interpretation of your results, so you understand what it means and what to do next.

Why Work With Me?

As a gut health expert, I was selected by Invivo as one of the first UK practitioners to pioneer the introduction of this test to the UK market in November 2024.

I've used gut testing for years to support clients with chronic health and gut issues, but this is the most advanced tool I’ve ever seen. It’s transformed how I help clients and the results they get.

Ready to finally understand your gut — and your health — on a whole new level?

Your Health is an investment. Not an expense.

And if you invest in learning how to take care of your gut health you'll feel the difference.
