Bloating. Food reactions. Unpredictable bowel habits. The same symptoms can have different contributors.
Still having gut symptoms after medical checks? Microbiome testing may add another piece of information for your practitioner to consider alongside your symptoms, diet and history.
It means looking at aspects of how the gut ecosystem functions, as well as which microbes are present. Some findings may help inform food, lifestyle or supplement choices. An unusual marker does not prove what caused your symptoms, and changing it does not necessarily improve how you feel. This complements medical investigation; it does not replace it.
Common reasons people start a conversation
People sometimes seek advice about skin concerns such as eczema, psoriasis, acne or rosacea, or notice changes after overseas travel, antibiotics, PPI use, infections (including gastro, COVID, parasites or H. pylori), stress, postpartum changes or menopause. PCOS may also be part of a person’s wider health history. These concerns can have many causes: this test does not diagnose them or establish that the microbiome caused them.
OUR PREFERRED GUT MICROBIOME TEST
We choose Microba because it combines detailed DNA-based microbiome profiling, functional insights and gut physiology markers in one report. That gives our practitioners more information to guide food choices, consider supplements and prioritise your next steps.
When diets, probiotics and supplements have left you guessing, we want a report that helps us look at the broader gut ecosystem and decide what is worth considering next.
| Other gut tests | Why we choose Microba MICROBA EXTENDED · YOUR INCLUDED TEST |
|---|---|
| The level of detail varies. Some tests look for a selected list of organisms or report broader bacterial groups. | A detailed view of your gut ecosystem. DNA sequencing profiles microbes at species level, alongside their relative abundance, diversity and richness. |
| A list of microbes is only part of the picture. How much a test tells you about microbial functions and gut physiology depends on the test. | Insight into what those microbes may do. Functional markers, including butyrate-, methane- and hydrogen sulphide-associated groups, sit alongside gut physiology markers for added context. |
| Finding information is the first step. The depth of interpretation and guidance available with a report varies between providers. | A report we can use to guide your care. Evidence-graded insights help our practitioners assess food, fibre and supplement options against your results, symptoms and history. |
Features vary between providers and test types. Microba is our preference for this combination of detail and practitioner guidance; the right test still depends on your needs.
FROM YOUR REPORT TO YOUR NEXT STEP
Microbial diversity and fibre-related patterns help us discuss which foods and fibres to prioritise, introduce gradually or adjust to your tolerance.
Your report helps your practitioner assess whether a prebiotic, probiotic or other supplement is worth considering—and explain why.
Review what deserves attention first, what needs further assessment and whether a separate treatment consultation would be useful.
Species, relative abundance, diversity and richness.
Microbes associated with butyrate, acetate and propionate production.
Hydrogen sulphide, methane, ammonia and mucin-related microbial groups.
Markers including calprotectin, pancreatic elastase, secretory IgA and faecal pH.
Microbial function markers reflect potential, not directly measured gas or short-chain fatty acid levels. Microbiome profiling cannot prove the cause of symptoms or diagnose food intolerances; medical assessment may still be needed.

Microba Extended profiles the microbes in your stool, their diversity, selected microbial functions and gut physiology markers. Alongside your symptoms and history, this can help your practitioner discuss food and fibre choices, whether supplements are worth considering, and any further assessment. It cannot identify every food trigger, prescribe supplements on its own or prove what causes your symptoms.
Follow the instructions in your kit, collect your stool sample at home, package it as directed and drop it at the post office. No clinic visit is needed. Follow the collection and posting schedule supplied with your kit.
Microba lists a 14-day laboratory turnaround for the Extended test. Allow additional time for kit delivery, return postage and your results consultation. Processing times can vary.
No. This stool test largely reflects the large-intestinal microbiome; SIBO assessment is separate. Where appropriate, we start with Microba-informed care and review your progress before considering a SIBO breath test. Your practitioner may recommend earlier SIBO investigation or medical assessment based on your symptoms.
No. IBS requires clinical assessment. A microbiome test cannot diagnose IBS or rule out other conditions. Your GP or treating clinician remains an important part of your care.
Yes. A practitioner confirms testing suitability and interprets your findings alongside your symptoms, history and other investigations. A results consultation is included. If testing is not appropriate, we will explain your options.
We offer Australia-wide telehealth and at-home sample collection. Confirm delivery availability and return-postage arrangements with the team before ordering, particularly if you live remotely.
Stripe redirects you to Cliniko to book your included Meet and Greet with Josh. At that appointment, you can discuss the testing process and next steps. If you cannot access the booking page, contact the team using the phone or email below.
No. The package gives you the test and a consultation to understand your results. Dedicated naturopathy or clinical nutrition treatment plans, ongoing support, supplements and additional tests are optional and priced separately.
Ask your practitioner and follow your kit instructions. Preparation depends on medications, antibiotics and supplements. Do not stop prescribed medication without advice from your prescriber.
The $697 AUD upfront price includes a Meet and Greet with Josh, the Microba Extended gut microbiome test and a results consultation. Further treatment and supplements are separate. Confirm delivery, return-postage arrangements and payment terms before purchase.
A relaxed conversation directly with Josh about your questions and options, rather than a detailed clinical assessment. Allow around 15 minutes. You can ask whether testing is worth considering, what is included and what further care could involve.
Yes. The payment-plan total is $727 AUD: $30 more than paying upfront. This is the full price, not the instalment amount. Book a free call with Josh to agree on instalment amounts, dates and terms.
If your needs fall outside our scope or you are not progressing as hoped, we can discuss appropriate next steps and give you access to our list of trusted clinics.
