DIAGNOSTIC OVERVIEW

What Gut Microbiome Is

The gut microbiome is an active area of research, and its composition varies widely from person to person. This test profiles the bacteria present, looking at overall diversity and which species are represented. The science is still developing, so the result is best treated as useful insight to discuss rather than a fixed set of instructions.

Why it's worth it

Insight from a simple at-home sample.

Guidance, not an overwhelming data dump.

Steps you can genuinely act on.

DIAGNOSTIC DETAILS

What it measures

The test assesses microbiome diversity and species composition, profiling the bacterial community in your gut.

Your Microbiome

Profiles the trillions of bacteria living in your gut from a simple at-home sample, looking at their diversity and balance. This ecosystem influences digestion, metabolism and immunity, and it is one of the few parts of your health you can meaningfully shift through diet.

From an At-Home Sample

A simple, private sample you collect at home, no clinic visit needed.

Diversity and Balance

The analysis looks at how varied and balanced your gut community is, patterns linked to metabolic and digestive health. Read by a dietitian or clinician, it becomes practical guidance rather than an overwhelming data dump.

Turned Into a Plan

Findings translated into clear, evidence-aware steps you can act on.

Order online and your at-home collection kit is sent to you, with simple, clearly written instructions. There is no clinic visit needed to get started.

Collect at home

You take a small sample in private at home, following the instructions, and post it back in the prepaid packaging. Many people find this far easier than a clinic visit for this kind of test.

Lab analysis

Your sample is processed by a specialised lab that profiles the bacteria in your gut, assessing the overall diversity and which species are present.

Results in the app

Your microbiome profile lands in the Precursor app as a readable summary rather than a raw data dump, laid out in plain language you can make sense of.

Review and act

A clinician or dietitian helps you understand what your profile suggests and turns it into sensible, evidence-aware steps for your diet, without overreaching on what the science can claim.

"The microbiome is a fast-moving science, so we are careful not to overclaim. Used well, it gives people practical, evidence-aware ways to support their gut through the food they eat."

FAQs

Your Questions, Answered

How do I book a test?

Choose your test and a time that suits you online, then visit one of our partner locations. If any preparation is needed, such as fasting, we tell you clearly when you book.

When and how do I get my results?

Your results appear in the Precursor app once your sample or scan has been processed, laid out in plain language rather than a wall of numbers. Turnaround depends on the test, and we give you a timeframe when you book.

Will someone explain my results to me?

Yes. A clinician reviews your results, flags anything worth your attention and helps you understand what they mean and what, if anything, to do next. You are never left to interpret them alone.

Where can I get tested?

We operate nationally through a network of partner locations across most major cities and regional centres. When you book, you simply choose the location that is most convenient for you.

Do I need to prepare or fast beforehand?

It depends on the test. Some require fasting or other simple preparation, and others need nothing at all. Whatever applies, we tell you clearly at the time you book so there are no surprises on the day.

Can I track my results over time?

Yes. The Precursor app is built to show change between tests, so each result becomes a trend you can follow rather than a one-off snapshot. Retesting lets you see the effect of any changes you make.

How is my data handled and kept private?

Your health data is handled with care and kept private. Results are stored securely in the Precursor app and shared only with you and the clinicians involved in your care.

What happens if something needs further attention?

If your results surface something worth acting on, your clinician explains it calmly and talks you through sensible next steps. The aim is early clarity and considered action, never unnecessary alarm.
