What is Hydrogen Breath Testing?
Hydrogen Breath Testing (HBT) is a non-invasive, sensitive means of detection for gastro-intestinal disorders. Hydrogen breath tests make use of gut bacteria’s ability to digest sugars and convert these to hydrogen, which is then absorbed into the blood and can be measured in exhaled breath. The tests can be used to detect gastro-intestinal disorders like food malabsorption, sugar intolerances and Small Intestinal Bacterial Overgrowth (SIBO).
A group of patients does not produce hydrogen and would not be diagnosed by Hydrogen Breath Testing (HBT) alone. By performing Hydrogen and Methane Breath Testing (HMBT) misdiagnosing can be prevented for patients who don’t produce hydrogen, but methane or a combination of both.
