Lactulose is a prescription item. Accounts must have prescription authorization to complete orders.


This is a simple, non–invasive, gastrointestinal test that you perform in your home and mail back to our 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. Lactulose is included and is used as a challenge substrate; lactulose feeds the small intestinal bacteria so we can measure it. 


Any lactulose breath test ordered by non-prescribing accounts will result in suspension of the order and phone call to account's contact number.
