Small Intestinal Bacterial Overgrowth is a condition that can lead to gastrointestinal symptoms including gas, bloating, nausea, constipation, diarrhea and is associated with Irritable Bowel Syndrome (IBS). This breath test measures hydrogen and methane and helps to diagnose SIBO.
The breath test is a simple, non-invasive test. After a 24 hours preparatory diet, the lactulose (or glucose or fructose) test substrate is swallowed.
Lactulose is not absorbed and therefore acts as a food source for bacteria, if present, in the small intestine.
The bacteria ferment the testing substance and produce hydrogen and/or methane. These are diffused into the bloodstream and exhaled via the breath.
Breath samples are collected every 20 minutes for 3 hours. A third gas, hydrogen sulphide, can also be present but cannot be assessed via breath testing at this time.
All our tests use machines from QuinTron, the original manufacturer of BreathTracker, to measure both hydrogen and methane in a single sample of breath (alveolar air)
Testing for SIBO using the QuinTron BreathTracker is considered gold standard.
Extensive quality control, including carbon dioxide measurements to assure an acceptable alveolar air sample, comply with the highest standards of analytical excellence.
