The Gastrointestinal Microbial Assay Plus (GI-MAP) is a comprehensive clinical tool that measures the gastrointestinal microbiome from a single stool sample using quantitative polymerase chain reaction (qPCR) technology.


The GI-MAP is designed to assess a patient’s microbiome with particular attention to microbes that cause disease or that disrupt normal microbial balance and contribute to perturbations in the GI flora and contribute to illness. With full PCR quantification, we can now see the level of infection thus, providing accurate, actionable clinical information. The results gleaned from this digestive profile help the clinician to provide personalized, targeted protocols to address gut dysfunction.


Gastrointestinal function is critical for good health. In addition to performing digestive functions, the intestinal tract contains significant amounts of organisms. Imbalances in this internal ecosystem and the overall GI function is associated with a wide variety of common illnesses including, but not limited to:


  • Irritable Bowel Syndrome (IBS)

  • Inflammatory Bowel Disease (IBD)

  • Diabetes

  • Obesity

  • Cardiovascular Disease

  • Celiac and Other Malabsorption Disorders

  • Mood Disorders

  • Autoimmune

  • Autism
