SIBO Glucose (Small Intestinal Bacterial Overgrowth)


This test assists in the diagnosis and care for patients suffering from SIBO and Lactose, Fructose and Sucrose intolerance using glucose as the substrate. The test provides a convenient breath collection device that allows patients to gain access to this test without having to go to a clinic or hospital.


The breath collection device included in the kits ensures accurate measuring of alveolar air and not room air, thus guarding against potential false negatives associated with other breath collection processes. Within 72 hours the lab will provide a detailed report with the information you need to make critical treatment decisions.
