SIBO Test (Breath)
SIBO Breath Testing & Advanced Gut Assessment
Clinical Testing via Accredited Australian Labs
 
If you rely on restrictive diets to manage digestive symptoms, there may be an underlying reason.
Clinical research estimates that up to 78% of people diagnosed with IBS may have Small Intestinal Bacterial Overgrowth, SIBO.
 
What Is SIBO?
SIBO occurs when excess bacteria grow in the small intestine and ferment food before it is fully digested. This early fermentation can trigger uncomfortable and persistent digestive symptoms.
 
SIBO can contribute to:
  • Persistent bloating
  • Altered bowel habits
  • Upper abdominal distension
  • Reflux
  • Food reactions
Our hydrogen and methane breath testing helps determine whether SIBO may be driving your symptoms and provides clear guidance on what to do next.
 
Choose Your Assessment Option
Note: Both options include hydrogen and methane analysis and personalised interpretation and guidance.
 
OPTION 1. Standard SIBO Test
  • 3-Hour Breath Test (lactulose)
  • Hydrogen + Methane Analysis
  • Results within 2 business days
 
Our recommended starting point for most patients experiencing bloating or altered bowel habits.
Price: $369
 
Important: Breath testing evaluates hydrogen and methane SIBO only. It does not reliably detect sulphide-dominant SIBO, SIFO, or broader microbiome imbalance.
 
Option 2. Advanced Gut & SIBO Assessment
SIBO Breath Test + Complete Microbiome Mapping (stool)
  • Combines breath testing with advanced stool microbiome analysis for a broader understanding of your gut ecosystem.
  • SIBO results available within 2 business days following receipt of your sample, stool results typically take 10-15 business days. Results issued in 2 parts to minimise delays. 
 
Assesses:
  • Gas overgrowth patterns
  • Bacterial imbalance
  • Fungal markers
  • Microbial diversity
  • Inflammatory indicators
  • May detect causes of sulphide SIBO subtype
 
Often chosen by patients with recurrent or complex symptoms who want to minimise trial-and-error treatment.
 
Combined Package Price: $959
Purchased Separately: $1,019

    • This is an at-home test. Detailed preparation instructions are provided with your kit.

    • A specific pre-test diet is required for 24 hours prior to testing to ensure accuracy.

    • Testing takes approximately three hours and must be completed in the morning. A two-hour test is available if requested but may miss important later-stage gas production.

    • Certain non-prescription medications and supplements may need to be paused prior to testing. We will never advise to pause prescribed medications - if medications may impact your results we will advise for you to discuss with your prescribing practitioner if the test is still right for you and, if so, a suitable action plan .

    • SIBO breath test results are typically available within 1–2 days of the laboratory receiving your samples.

    • Complete Microbiome Mapping results, if added, are typically available within 10–14 days. Results are sent separately to prevent delays. 

    If you are currently pregnant, diabetic, have recently taken antibiotics, or are unsure whether testing is appropriate, please contact us before ordering. This may not be right for you.
