Gut Microbiome Testing in Brisbane
In short
Gut microbiome testing is a specialised stool test that profiles the bacteria living in your digestive tract. These microbes play a role in digestion, metabolism and immune function. At Colonoscopy Brisbane, Dr Goutham Sivasuthan offers microbiome testing in Brisbane as part of a wider gut-health assessment and interprets the report alongside your symptoms. The clinical value of these tests is still being studied, so decisions about diet and treatment draw on the whole assessment.

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.
A stool sample provides a profile of the bacteria present. Dr Goutham interprets that profile with your symptoms, medical history and other findings. Research into how these reports improve treatment decisions is still developing.
Microbiome testing within a gut-health assessment
Persistent digestive symptoms are assessed in the context of your history and previous tests. This assessment helps establish whether a microbiome profile would add useful information. Symptoms include:
- Bloating and excessive wind
- Irritable bowel syndrome (IBS)
- Food sensitivities and intolerance
- Altered bowel habits
- Other unexplained gastrointestinal symptoms
If symptoms continue after a normal colonoscopy or other structural tests, a wider gut-health assessment can consider what to investigate next. Red-flag causes need to be excluded before symptoms are attributed to IBS.
Understanding your microbiome test results
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.
Dr Goutham considers your symptoms, nutritional needs and wider assessment when advising on diet. The microbiome report contributes to that discussion alongside the other clinical findings.
