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.
