SIBO Basic


This test is the foundation of SIBO testing. You will receive a test kit containing the breath sample collection device, 10 test tubes, and the testing substrate lactulose. After following the preparation instructions, you will drink the lactulose mixed with water after collecting a baseline sample. Once the lactulose arrives in your small intestines, bacteria present in SIBO will start to ferment this sugar and produce gas which is captured with the breath test Sometimes the test is negative, even though SIBO is present. This is due to the fact that not all bacteria can ferment/use lactulose to produce gas

SIBO Advanced


Lactulose + Glucose. This test builds on the SIBO Basic by adding one extra/additional test sugar. You will complete the second test (Glucose) the day after completing the Lactulose breath test. Glucose is also fermented by SIBO bacteria and may capture more bacteria that where missed by Lactulose Like shining a brighter light to see what’s there, this combination test may increase your chance of a positive SIBO diagnosis

SIBO Comprehensive


Lactulose + Glucose + Fructose. This test leaves no stone unturned! This triple approach shines the brightest light and has the highest likelihood of finding fermentation and gas production if it is present. Additionally, if your test is positive for SIBO, it can let you know if fructose needs to be avoided during the treatment diet. Express Shipping and Return Satchel included in Shipping.

Fructose Malabsorption


Fructose malabsorption is a common genetic condition Many people with SIBO find that they also cannot tolerate fructose containing foods (e.g fruit, honey) and this test helps to identify if malabsorption is an issue This test is not a stand alone test for SIBO but is helpful as an add on.
