Other available stool tests may appear to be DNA-based, but they are in fact only using matrix assisted laser desorption/ionization time-of-flight (MALDI-TOF) to identify stool microbes. Their methodology relies on cultures from stool and is not molecular/PCR based assays. With a culture-based test it is not possible to measure strict anaerobes, viruses or virulence factors. They also lack the ability to deliver true quantitation of any of the reported organisms.
In addition, other recent test offerings using an FDA-cleared molecular technology only for pathogens do not extend any molecular methodology over an entire comprehensive stool analysis to include opportunistic and beneficial organisms, including bacteria, protozoa, and fungi, all of which are provided through the GI-MAP™.
There have been many advances in DNA technology over the last 10 years, including an FDA approved, PCR based technology and assay that is used by major hospital labs. Considering these advances, why would you still rely on culture and microscopy for stool analysis and assessment of the GI environment?
