This is a simple, non–invasive, gastrointestinal test that you perform in your home and mail back to our clinic laboratory. It detects bacterial overgrowth in the small intestine and is used to diagnose Small Intestinal Bacterial Overgrowth (SIBO). SIBO is a common gastrointestinal disorder that lead to the common IBS symptoms of bloating, gas, diarrhea, constipation/ irregularity, and abdominal pain. SIBO activity can also result in many extra-GI symptoms including insomnia, anxiety, chronic fatigue, fibromyalgia, migraines, headaches, muscle pain and many other symptoms that escape diagnosis.


This test requires a 1-2 day preparation diet, an overnight fast and 3-hours of collection time. Glucose is included and is used as a challenge substrate; glucose feeds the small intestinal bacteria so we can measure it. If you are diabetic or have some other condition that does not allow for the use of glucose, it is recommended to order a lactulose version of this test; which requires a drug prescription on file before test shipment.
