Gut Health &

Microbiome Testing

Your gut does more than digest food. It plays a central role in your immune system, hormone balance, mood, and overall wellbeing.

When the gut is out of balance, it can show up as bloating, reflux, fatigue, skin issues, autoimmunity, or even mood changes.At Essencia Wellbeing, I offer a suite of advanced gut tests that provide clear, scientific insights into your microbiome, barrier function, digestion, and small intestine health. These premium tests are processed by accredited Australian laboratories and give us the data we need to guide targeted care.

Tests are processed by leading accredited Australian and international laboratories.

GI360 Microbiome Profile.

GI360 Microbiome test for gut health assessment with Naturopath Catrina Bleicher

The GI360™ uses advanced DNA mapping and MALDI-TOF technology to provide a complete snapshot of the gut microbiome and gastrointestinal environment. This test identifies beneficial bacteria, pathogens (including parasites and yeast), digestive function markers, inflammation, and immune status—all crucial data for personalised gut health strategies.

What it Measures:

  • Pathogens: bacteria, fungi, parasites, viruses

  • Beneficial/commensal bacteria (abundance and diversity)

  • Inflammation: calprotectin, lactoferrin, secretory IgA, zonulin

  • Digestion: pancreatic elastase, short-chain fatty acids, stool pH, putrefactive metabolites

  • Dysbiosis Index – validated scoring of microbiome balance

Who Benefits:

Individuals with IBS, IBD, bloating, food sensitivities, chronic fatigue, autoimmune disorders, and skin issues will gain insight into hidden causes and directed solutions.

Why it’s Useful:

  • Combines multiple technologies for greater clinical accuracy

  • Identifies both infections and functional imbalances

  • Includes antimicrobial susceptibility testing to guide targeted care

  • Best for complex GI cases, unresolved symptoms, or inflammatory gut conditions

Sample: Simple home stool collection.

Turnaround time: 3–4 weeks

MetaXplore GI Plus

MetaXplore Comprehensive microbiome testing from Co-biome  with Essencia Wellbeing

MetaXplore GI Plus delivers next-generation gut microbiome and gastrointestinal health analysis.

It combines whole-genome metagenomic sequencing with GI marker analysis to reveal microbial community balance, gut function, and inflammation for truly personalised gut care. It measures bacteria, fungi, viruses, parasites, and archaea while also exploring functional pathways such as butyrate production, methane, histamine, vitamin synthesis, and toxin metabolism. Biomarkers like calprotectin, zonulin, secretory IgA, lactoferrin, and pancreatic elastase give additional insight into inflammation, barrier integrity, and digestive function.

What it Measures:

  • Full microbial spectrum: bacteria, fungi, viruses, parasites, archaea

  • Functional potential: butyrate and SCFA synthesis, methane, histamine, vitamin pathways, toxin metabolism

  • Biomarkers: calprotectin, secretory IgA, zonulin, lactoferrin, pancreatic elastase

  • Microbiome diversity and resilience scores

Who Benefits:
Those with abdominal discomfort, bloating, IBS, constipation or diarrhoea, immune and metabolic issues.

Why it’s Useful:

  • Offers the broadest microbial coverage available worldwide

  • Goes beyond detection to explain how microbes are functioning

  • Links gut ecology to mood, cognition, metabolism, and immune health

  • Best for chronic, systemic, or complex conditions, and for patients interested in long-term prevention and resilience

Sample: Home stool sample kit.

Turnaround: 4-5 weeks.

Supplier: Co-Biome

Technology: Whole-genome shotgun metagenomic sequencing (approximately 28,000 species) plus ELISA biomarkers and qPCR.

gut barrier panel test for leaky gut available through Essencia Wellbeing naturopath in Sydney

Gut Barrier Panel

This panel measures markers of gut lining health: Zonulin (tight junction integrity), Occludin, Candida reactivity, and LPS (endotoxin exposure). Results clarify gut permeability (“leaky gut”), digestive inflammation, and immune reactivity.

What it Measures:

  • Zonulin and occludin: gut junction integrity

  • LPS antibodies: bacterial endotoxin leakage

  • Candida antibodies: fungal overgrowth or mucosal disruption.

Who Benefits:

Chronic GI symptoms, food reactions, autoimmune issues, fatigue, skin problems.

Why it’s Useful:

  • Focused evaluation of intestinal permeability, also known as “leaky gut”

  • Explains systemic symptoms such as fatigue, skin flares, and autoimmunity

  • Supports personalised gut repair strategies including dietary support, mucosal nutrients, anti-inflammatories, and probiotics

  • Best for clients with systemic inflammation or immune issues linked to gut dysfunction.

Sample: Blood sample.

Turnaround: 3-4 weeks

Supplier: Doctors Data (USA), via RN Labs, Australia

Technology: Blood-spot immunoassay (zonulin, occludin, LPS, Candida antibodies).

SIBO Comprehensive Breath Test

SIBO Comprehensive breathtest for digestive health assessment with Sydney Naturopath Essencia Wellbeing

The SIBO Comprehensive breath test detects hydrogen and methane bacterial overgrowth in the small intestine—clinically linked to IBS, bloating, and nutrient malabsorption.

What it Measures:

  • Hydrogen and methane gases over time

  • Options for glucose, lactulose, or fructose substrates

Who Benefits: Those with IBS, chronic bloating, unpredictable bowels.

Why it’s Useful:

  • Detects bacterial overgrowth in the small intestine

  • Differentiates hydrogen-dominant versus methane-dominant SIBO

  • Explains symptoms such as bloating, reflux, diarrhoea, constipation, or IBS-like patterns

  • Best used when symptoms or other test results suggest small intestinal overgrowth is a likely driver.

Sample: At-home breath collection kit

Turnaround: 1–2 weeks

Supplier: SIBO test via RN Labs, Australia

Technology: Hydrogen and methane breath gas analysis after carbohydrate challenge.

Gut Function Testing – FAQs

  • No. They identify imbalances and functional issues that help guide treatment, but they do not provide medical diagnoses.

  • Not automatically. We use results to create a tailored plan. Food elimination is guided by both test findings and your symptom history, often with a structured re-introduction phase.

  • For the most accurate results, avoid testing straight after antibiotics, probiotics, or during strict elimination diets, as these can mask findings. Testing is most useful when your routine is stable, and not during an acute flare-up.

  • Your practitioner will use the results to design a targeted plan, which may include dietary adjustments, probiotics, or other supportive therapies.

  • Yes. Antibiotics taken in the last 4–6 weeks can alter microbiome results. Always let your practitioner know about recent medication use before testing.

  • Yes. Antibiotics taken in the last 4–6 weeks can alter microbiome results. Always let your practitioner know about recent medication use before testing.

  • Sometimes. Retesting a few months after intervention can help track progress and fine-tune your treatment plan, but it’s not always necessary.
