  • GI-MAP® (GI Microbial Assay Plus)

    Research overwhelmingly indicates that gut health impacts overall health. The gut microbiome plays a critical role in mediating the effects of diet, digestion, immunity, metabolic function, and more. This GI-MAP (Microbial Assay Plus) test is truly unique in the field – relying exclusively on quantitative polymerase chain reaction (qPCR) technology to detect parasites, bacteria, fungi, and more by targeting the specific DNA of the organisms tested. The quantitative insights provided in this process, known for accuracy and reliability, allow practitioners to create more personalized treatment protocols for optimizing gut function and addressing dysfunction.

  • SIBO - 3 Hour

    When it comes to gastrointestinal symptoms, studies have shown that a large percentage of Irritable Bowel Syndrome (IBS) is actually Small Intestinal Bacterial Overgrowth (SIBO). SIBO is a common clinical condition characterized by excessive bacterial development in the small intestine. This non-invasive breath test captures exhaled hydrogen and methane, to provide practitioners with the insight to better differentiate and diagnose SIBO.
