Measure Your Microbiome and Gut Health
Gut & Microbiome Testing
Gut microbiome testing is one of the most advanced ways to assess digestive health and uncover the root causes of ongoing gut symptoms. At Dr Brad Leech, we offer comprehensive microbiome and stool testing in Australia (including Microbiome Explorer) to help identify dysbiosis, inflammation, IBS drivers, and microbial imbalances. This type of assessment can be especially valuable if you’re experiencing issues such as bloating, constipation, diarrhoea, abdominal pain, food sensitivities, or chronic digestive discomfort. By exploring your unique gut microbiome, we can gain deeper insights and create personalised, evidence-based strategies to improve your overall health and wellbeing.

Microbiome Testing in Australia – Comprehensive Gut Health Assessment
Understanding your gut microbiome is key to addressing a wide range of health concerns—from digestive discomfort to immune dysregulation and mental wellbeing. That’s why I use the Microbiome Explorer range of gut microbiome tests, developed by Microba, leaders in metagenomic sequencing.
Depending on your location, different versions of the test are available:
🌏 Australia – Microbiome Explorer Comprehensive
The Microbiome Explorer Comprehensive ($549+ Postage) is the most comprehensive gut health assessment currently available. It combines shotgun metagenomic sequencing with biomarker testing to provide a deep and functional understanding of your gut ecosystem. This includes:
A full microbial profile (bacteria, fungi, parasites, and viruses)
Insights into microbial diversity and balance
Functional pathways (e.g., SCFA production, vitamin synthesis, inflammation modulation)
Biomarkers such as:
Zonulin (intestinal permeability)
Calprotectin and Lactoferrin (gut inflammation)
Secretory IgA (mucosal immunity)
Pancreatic elastase (digestive enzyme function)
Occult blood and faecal pH
This test is ideal for those with complex, chronic, or unresolved health concerns, including IBS, IBD, autoimmune conditions, fatigue, or skin and mood issues.
🇳🇿 New Zealand – Microbiome Explorer Essential
In New Zealand, the baseline Microbiome Explorer Essential test is available for $449 + Postage. It offers powerful insights through whole-genome metagenomic sequencing, allowing us to:
Identify microbes at the species level
Assess microbial diversity and dysbiosis
Analyse key functional pathways (e.g., butyrate production)
Explore dietary interactions and fibre fermentation patterns
While this version does not include the additional biomarkers of the Microbiome Explorer Comprehensive, it still provides a robust foundation for personalised gut health support.
The Microbiome Explorer Essential is also the preferred test for paediatric patient (<6 years of age)
