Breath Gas Testing Equipment for SIBO Diagnosis

Breath gas testing is the most widely used and non-invasive method for diagnosing Small Intestinal Bacterial Overgrowth (SIBO). It is undertaken to diagnose the presence of excessive bacteria in the small intestine, which can interfere with digestion and nutrient absorption. 

This article provides an overview of SIBO testing products and related supplies. 

Why SIBO Diagnosis Matters 

SIBO testing confirms the presence of bacterial overgrowth in the small intestine. It differentiates between hydrogen-dominant and methane-dominant overgrowth, also known as IMO – Intestinal Methanogen Overgrowth. 

SIBO is often secondary to other conditions, including: 

• Irritable Bowel Syndrome (IBS) – especially IBS-D (diarrhea) and IBS-C (constipation) 

• Celiac disease 

• Crohn’s disease and other forms of IBD 

• Gastroparesis (delayed stomach emptying) 

• Diabetes 

• Hypochlorhydria (low stomach acid) 

• Post-surgical changes (e.g., bowel resections, adhesions) 

• Small bowel diverticulosis 

Untreated SIBO can lead to: 

• Chronic inflammation 

• Malnutrition 

• Fat-soluble vitamin deficiencies 

• Neurological symptoms (e.g., brain fog) 

• Worsening of underlying GI conditions 

How SIBO Testing Works

SIBO breath testing measures the levels of hydrogen (H₂) and methane (CH₄) gases in a patient’s breath after ingesting a sugar solution (typically lactulose, fructose or glucose). These gases are produced by bacteria in the small intestine when they ferment the sugar. Elevated levels suggest bacterial overgrowth. 

Testing involves a preparation period for the patient, such as a restricted diet for 24 hours and fasting for 12 hours before testing. 

The testing procedure involves the patient ingesting a sugar substrate (lactulose or glucose). Breath samples are collected at 15–20 minute intervals over 2–3 hours. The samples are then analysed for H₂ and CH₄ concentrations. 

Key Features of SIBO Testing Equipment in Australia

When choosing SIBO testing equipment, buyers should consider: 

• Dual-Gas Detection. The equipment must detect at least Hydrogen (H₂) and Methane (CH₄). 

• CO₂ Correction. Does the equipment ensure sample integrity and accuracy by verifying that breath samples are not contaminated with room air? 

• High Sensitivity and Precision. Equipment should detect gas concentrations in parts per million (ppm) and use solid-state sensors or gas chromatography technologies. 

• User-Friendly Interface. Does the equipment have transparent digital displays and intuitive controls, and what is the standard of the associated analysis software? 

• Sample Collection Supplies. Is the equipment supported by high-quality supplies that ensure test accuracy? 
  
  
• Regulatory Compliance. Equipment should be TGA-approved and backed by clinical validation.
