Riverine Herald source Yarrawonga Chronicle sourceWHY LOOK CLOSER?
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.
THE PRACTICAL BENEFITS
Your test findings help us turn a detailed microbial profile into practical food changes and, where appropriate, targeted supplement recommendations.
We combine your test findings with your symptoms and food history to recommend foods to adjust or trial for better digestive comfort.
Your microbial profile helps guide the fibres and plant foods we recommend, introduced gradually to support your microbiome and suit your tolerance.
Your results help our naturopaths assess whether a supplement is appropriate, then recommend a product, dose and review plan suited to you.
WHY THAT MATTERS
Start with food and supplement priorities informed by your results, rather than repeatedly trying an unstructured approach.
Understand why a supplement is recommended and when to review it—helping you avoid spending on products without a clear purpose.
Testing does not prescribe a diet or supplement on its own. Recommendations and outcomes depend on your clinical assessment.
LOOK BEYOND THE TEST
A test gives you information. The practitioner you choose helps turn it into a treatment plan.
Linda SpirouGut Health NaturopathWhen comparing clinics offering Microba, ask about the practitioner’s training in gut health and report interpretation—not just which test they offer.
Linda holds both of these certifications from the Microbiome Restoration Center, alongside her degree and additional gastrointestinal training.
Meet Linda & our team
Focused practitioner education in gut health, supporting a considered approach to your care.
Specific training in microbiome report interpretation, considered alongside your clinical history.
Certifications shown are Linda Spirou’s. Training informs care; it does not guarantee a particular treatment outcome.
WHY WE USE MICROBA
We choose Microba for its species-level profiling, functional insights and practitioner report. Interpretation is what connects the data to your care.
The variety and spread of microbial species detected in your sample.
IN EVERY PACKAGEWhich organisms are present, and their relative abundance.
IN EVERY PACKAGEButyrate, acetate and propionate-associated groups. Microbial potential, not a direct metabolite measurement.
IN EVERY PACKAGEHydrogen sulphide, methane, mucin consumption and other reported functional groups.
IN EVERY PACKAGECalprotectin, lactoferrin, faecal occult blood, pancreatic elastase, secretory IgA, zonulin-family peptides and faecal pH.
IN EVERY PACKAGEYour practitioner brings the results together with your symptoms and history to agree on next steps.
RESULTS CONSULTATION INCLUDEDMicroba Extended is included in all three packages. A targeted pathogen panel is not included. Microbiome profiling is not a standalone diagnostic test.
BEYOND THE NUMBERS

Want to talk it through with a person?
Book a Free Gut Health Clarity CallNew, severe or worsening symptoms, blood in your stool or unexplained weight loss need medical assessment. Do not delay care while waiting for a microbiome test.
It gives your practitioner a picture of the microbes in your stool, their diversity and selected microbial functions, alongside markers of gut physiology. The practical aim is to help you prioritise food changes, consider which fibres or foods may support your microbiome, and discuss whether a supplement is worth trying. Your symptoms, diet and medical history matter just as much: the report cannot identify every food trigger, tell you exactly which supplements you need, or prove the cause of your symptoms.
Your at-home collection kit includes instructions. Collect your stool sample at home, package it as directed, then drop it at the post office for return to the laboratory. There is no need to come into a clinic. Follow the collection and posting schedule supplied with your kit.
Microba lists a 14-day laboratory turnaround for the Extended test used in these packages. Allow additional time for kit delivery, return postage and your results consultation. Processing can vary; we will confirm the current estimate before you order.
No. This stool test provides information about the gut microbiome, largely reflecting the large intestine; it does not diagnose small intestinal bacterial overgrowth (SIBO). Where appropriate, our clinic starts with Microba-informed care for the large-intestinal microbiome and reviews your progress. If symptoms or clinical findings warrant it, we then discuss separate small-intestinal assessment, such as SIBO breath testing. This is our staged approach, tailored to you—not a rule that everyone must follow. Your practitioner may recommend earlier medical assessment or SIBO investigation when needed.
No. IBS requires a clinical assessment. A microbiome test cannot diagnose IBS, rule out all other conditions, or show that a particular microbe caused your symptoms. Your GP or treating clinician remains an important part of your care.
Yes. Microba testing is arranged through a qualified practitioner. We review suitability before ordering and interpret the findings alongside your symptoms, history and other investigations. If testing is not the right next step, we will explain your options.
The Gut Guy offers Australia-wide telehealth and at-home sample collection. Confirm delivery availability and return-postage arrangements for your location before ordering, particularly if you live remotely.
Every package includes a Meet and Greet with The Gut Guy and a results consultation. Test & Treat also includes a naturopathy treatment consultation. Complete Care adds clinical nutrition, three 15-minute clinical progression phone calls and four months of 1:1 support and clinical adjustments with Josh, within scope and with practitioner input where needed. Together, we help you understand the findings and agree on practical next steps.
Ask your practitioner and follow the instructions supplied with your specific kit. Preparation can depend on antibiotics, medications and supplements. Do not stop prescribed medication without advice from the prescriber.
Test & Understand ($697 upfront / $727 payment-plan total) includes a Meet and Greet with The Gut Guy, the Microba gut microbiome test and results consultation. Test & Treat ($937 / $967) adds a gut health naturopathy treatment consultation. Complete Care ($1,498 / $1,528) includes those services plus a clinical nutrition treatment consultation, three 15-minute clinical progression phone calls and four months of 1:1 support and clinical adjustments with Josh. All amounts are AUD. Supplements and additional tests are separate. Confirm delivery, return postage, support arrangements and payment terms before purchase.
You speak directly with Josh. It is a relaxed conversation about your questions, goals and possible next steps, rather than a detailed clinical assessment. Allow around 15 minutes; the call can be shorter or longer depending on what you need and the time available. You will have space to explain what has been difficult, ask about the packages and leave with a clearer direction. Josh will have a genuine conversation about your options, including another service if it may be more suitable.
Yes. Each payment plan adds $30 to the upfront package price: $727 for Test & Understand, $967 for Test & Treat, or $1,528 for Complete Care. These are the total prices, not the instalment amounts. Book a complimentary call with Josh to agree on weekly or fortnightly amounts, dates and full terms.
No clinic can help everyone. If your needs fall outside our scope or you are not progressing as hoped, we will discuss your next steps openly. You can access our list of trusted clinics through the team, with suggestions suited to your needs. This can save you hours of research and help you avoid spending time and money on services that may not fit. We are not affiliated with these clinics, and a referral cannot guarantee a particular outcome.
