4-Pillar Gut Profile

$1,099.00 AUD

Want to investigate your gut health from every angle — microbiome, food reactions, gut lining, and bacterial overgrowth — all in one test?

The 4-Pillar Gut Profile is one of the most thorough gut health investigations available, combining four specialised tests into a single comprehensive panel. It covers microbiome mapping, food sensitivity testing, intestinal permeability assessment, and SIBO breath testing — giving your practitioner a complete, multi-angle view of your digestive health.

Rather than ordering multiple tests separately and piecing results together, this profile provides a structured, systematic investigation that covers the most common drivers of chronic gut issues. It's designed for people who want comprehensive insights and a clearer direction for treatment.

Overview

Gut health is complex, and a single test rarely tells the whole story. The 4-Pillar Gut Profile was designed to investigate the four most important dimensions of digestive function in one comprehensive panel, removing the guesswork from chronic gut issues.

Pillar 1 — Complete Microbiome Mapping:
A quantitative PCR stool analysis that screens for bacteria, viruses, fungi, parasites, and worms, along with key digestive and immune markers like calprotectin, zonulin, and pancreatic elastase. This provides insights into what's living in your gut and how well your digestive system is functioning.

Pillar 2 — IgG96 Food Sensitivity Testing:
A blood-based panel measuring IgG antibodies to 96 common foods. Elevated antibodies may indicate immune reactivity to specific foods, which can contribute to inflammation, bloating, skin issues, and fatigue. Identifying and temporarily eliminating trigger foods can help reduce symptoms.

Pillar 3 — Intestinal Permeability (Leaky Gut):
Assesses the integrity of your gut lining. When the intestinal barrier becomes compromised, partially digested food particles and toxins can pass into the bloodstream, potentially triggering immune responses and widespread symptoms. This test helps assess whether intestinal permeability may be contributing to your health concerns.

Pillar 4 — SIBO Lactulose Breath Test:
A breath test measuring hydrogen and methane gases to screen for small intestinal bacterial overgrowth. SIBO is a common but often under-investigated contributor to bloating, gas, and irregular bowel habits.

Together, these four pillars provide your practitioner with a solid foundation of investigation to build a targeted treatment plan.

Symptoms

This profile is designed for anyone with complex or persistent gut issues who wants a thorough investigation without ordering multiple tests separately. It's particularly valuable for people with chronic IBS symptoms, suspected food sensitivities, possible leaky gut, recurrent SIBO, or overlapping digestive and systemic symptoms (such as fatigue, skin conditions, or joint pain alongside digestive complaints). Practitioners use this profile as a comprehensive baseline when symptoms suggest multiple contributing factors.

Questions

  • Gut health issues rarely have a single cause. Bloating could be driven by SIBO, food sensitivities, microbial imbalances, or a compromised gut lining — or a combination of all four. Testing all pillars at once gives your practitioner the full picture, so treatment addresses root causes rather than just symptoms.
  • The profile involves stool collection (for microbiome mapping), breath samples (for SIBO testing), and a blood sample (for food sensitivity testing). Each component has its own collection kit with clear instructions. While it's more involved than a single test, the comprehensive data you receive is well worth the effort.
  • Results are typically available within 14 business days after the laboratory receives all your samples. Some pillars may return sooner than others.
  • The results of this profile are detailed and interconnected. We strongly recommend working with a qualified healthcare practitioner who can interpret the findings across all four pillars and design an appropriate treatment plan. We can help you find a practitioner if you don't already have one.
  • The Complete Microbiome Mapping is just one of the four pillars in this profile. On its own, it tells you about your gut bacteria and digestive markers. The 4-Pillar Profile adds food sensitivity testing, intestinal permeability, and SIBO breath testing — covering dimensions that the microbiome test alone can't assess.
  • Each pillar has its own preparation requirements. The SIBO breath test requires the most preparation (restricted diet and overnight fast). The stool and blood collections are straightforward. Your kit includes detailed instructions for each component, and we recommend allowing a few days to complete all collections.

How to prepare

This profile involves multiple collection types, each with its own preparation requirements. Your kit will include detailed instructions for each component. In general: for the SIBO breath test, follow the restricted diet for 24 hours before and fast for 12 hours overnight. For the stool collection, follow the enclosed instructions and return samples promptly. The IgG96 food sensitivity test requires a blood sample collected using the kit provided. Your practitioner may advise stopping probiotics or antimicrobials before collection — check with them first. Allow extra time for this profile as you'll be managing multiple collection steps.

After the test

Work with a practitioner experienced in functional gut health to review all four pillars together. Treatment is typically phased: addressing infections or SIBO first, then supporting gut repair and rebalancing the microbiome, while managing food sensitivities through guided elimination. The interconnected nature of the results means that treating one area often improves the others. Retesting individual pillars after 3-6 months helps track progress and adjust the treatment plan.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

You'll receive results for each of the four pillars, which your practitioner will interpret as an interconnected picture rather than isolated findings. The microbiome mapping reveals microbial imbalances, infections, and digestive function. Food sensitivity results highlight immune-reactive foods that may be driving inflammation. Intestinal permeability results show whether your gut lining is compromised. SIBO results indicate whether bacterial overgrowth in the small intestine is contributing to your symptoms. Often, these findings are related — for example, SIBO can cause leaky gut, which can trigger food sensitivities. Your practitioner will connect these dots and prioritise treatment accordingly.

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

"I'm a little biased as I work here! However, I love that The Bloody Good Test tracks my health over time. After turning 40, I wanted to make sure I wasn't going to drop dead from something basic I should have known about earlier. Measuring all my core biomarkers each year gives me peace of mind my health is on the right track"
