Provider Services


We provide a unique array of testing for Gastroenterologists. From our pathogens profile to our H.pylori gastric biopsy testing, we have expanded upon the familiar to include novel diagnostic tools such as virulence factors and antibiotic resistance genes.

Personalized Medicine

Our research and technology is advancing the field of personalized medicine. Using true quantitative PCR DNA analysis coupled with ongoing educational and technical support, we provide our practitioners the tools to help patients in ways that others cannot.

Scientific Support

The science behind our testing. Read the GI-MAP white paper, see sample reports, and learn from peer reviewed articles.

Additional educational materials may be found in our resource library.

Revolutionizing the Comprehensive Stool Analysis

Microscopy and culture-based tests are familiar, but they have limitations with sensitivity, specificity, and identifying anaerobic organisms.

That is why almost no peer-reviewed research studies have used microscopy and culture-based testing methods in over 20 years.
