SIBO Breath Test

Hydrogen/Methane Breath Test


Small Intestinal Bacterial Overgrowth can  be diagnosed by testing your breath samples for levels of hydrogen, methane, or both. After ingesting a lactulose test substrate, you produce breath samples every 20 minutes over a 3-hour period, in the comfort of your own home.

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 blood stream and exhaled via the breath. Breath samples are collected every 20 minutes for 3 hours.

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.
