We partner with Research Nutrition to provide functional testing for SIBO. It’s simple, and non-invasive.

What is SIBO (Small Intestinal Bacterial Overgrowth)?

Normally, bacteria are found in the trillions in the LARGE INTESTINE, where they perform various symbiotic functions for the human body. SIBO is a condition where bacterial overgrowth occurs in the absorptive area of the body, i.e. the small intestine.

• The breath test is a simple, non-invasive test. After a 24-hour preparatory diet, the lactulose (or glucose or fructose) test substrate is swallowed.
• Lactulose is not absorbed, and therefore may act as a food source for bacteria, if present, in the small intestine.
• The bacteria may ferment the lingering substances and produce hydrogen, methane, or both. These gasses may then be diffused into the bloodstream and exhaled via the breath.
• Breath samples are collected every 20 minutes for 3 hours.
• All tests use machines from QuinTron, the original manufacturer of BreathTracker, to measure both hydrogen and methane in a single sample of breath (alveolar air).
• Extensive quality control, including carbon-dioxide measurements to assure an acceptable alveolar air sample, comply with the highest standards of analytical excellence.
