Gut Microbiome Testing in Brisbane

In short

Gut microbiome testing uses specialised stool testing to analyse the trillions of bacteria living in your digestive tract — microbes that play an important role in digestion, metabolism, immune function and overall health. When their balance is disturbed it can contribute to bloating, abdominal discomfort, altered bowel habits and food intolerance. The results help Dr Goutham build personalised dietary and lifestyle recommendations, as part of a broader, evidence-based approach to your gut health.

Diet and the gut microbiome
What it is

Understanding your gut bacteria

The gut microbiome is the community of trillions of bacteria and other microorganisms that live in the digestive tract. A healthy, balanced microbiome supports digestion, helps regulate the immune system and influences overall wellbeing.

Specialised stool testing analyses the types and balance of bacteria present, giving insight into your gut health that ordinary tests don’t show. It is best used as part of a comprehensive assessment rather than on its own, so the results can be interpreted in the context of your symptoms and history.

Who it helps

When microbiome testing may be useful

Gut microbiome testing may be helpful for people with persistent or unexplained digestive symptoms, including:

  • Bloating and excessive wind
  • Irritable bowel syndrome (IBS)
  • Food sensitivities and intolerance
  • Altered bowel habits
  • Other unexplained gastrointestinal symptoms

It is often considered when a colonoscopy or other structural tests are normal but symptoms continue — forming one part of a wider gut health assessment. Importantly, symptoms should never be assumed to be IBS until red-flag causes have been excluded.

How it works

From sample to personalised plan

Testing is simple and done at home using a stool-collection kit. The sample is analysed in a specialised laboratory, and Dr Goutham reviews the results alongside your symptoms, diet and history.

Based on the findings, he can provide personalised dietary recommendations and targeted strategies to support a healthier microbiome — for example adjusting fibre, fermented foods or specific dietary patterns — and coordinate any further investigations or treatment with your GP.

Gut Microbiome Testing FAQs

What does gut microbiome testing involve?
A simple stool sample collected at home is analysed in a specialised laboratory to assess the types and balance of bacteria in your gut. Dr Goutham then interprets the results alongside your symptoms and history.
Can it diagnose a specific disease?
Microbiome testing gives insight into gut health and guides dietary and lifestyle strategies, but it is not a stand-alone diagnostic test. It works best as part of a broader assessment that can also exclude structural causes.
Will I get a diet plan from the results?
Yes — based on your results, Dr Goutham can provide personalised dietary recommendations and targeted strategies to support a healthier microbiome.
Do I need a referral?
You are welcome to enquire directly, and a GP referral allows a Medicare rebate for the consultation. We work closely with your GP throughout.
How much does it cost?
Costs depend on the specific test used. Our team can discuss this with you — see our pricing and no-gap options.
