Measure Your Microbiome and Gut Health

Gut & Microbiome Testing

Exploring and understanding your microbiome and gut health can have far-reaching benefits for your overall well-being. This approach is particularly valuable if you're dealing with gastrointestinal issues, as it allows Dr Brad Leech to address the root cause. Additionally, by delving into the world of your gut microbiome, we can gain deeper insights into digestive complaints such as constipation, diarrhoea, bloating, and abdominal pain, leading to more personalised and effective strategies. Beyond digestive health, this assessment can help us uncover insights related to hormonal imbalances, metabolic and weight concerns, immune system health, and chronic inflammation, allowing us to take a proactive approach to enhance your overall health and well-being.

MetaXplore Testing Availability

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 MetaXplore range of gut microbiome tests, developed by Co-Biome by Microba, leaders in metagenomic sequencing.

Depending on your location, different versions of the test are available:

🌏 Australia – MetaXplore GI Plus

The MetaXplore GI Plus ($549) 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 – MetaXplore

In New Zealand, the baseline MetaXplore test is available for $369 + 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 GI Plus panel, it still provides a robust foundation for personalised gut health support.
