Note: Result turnaround times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Special Instructions: Ship to lab Monday-Friday only. Specimen MUST be received by the lab within 6 days of collection. If you cannot ship the specimen on the day of collection, please refrigerate the sample. Avoid taking aspirin for 2 days prior to collection. DO NOT discontinue any medications unless directed by your physician.
Description: The GI-MAP stool test utilizes cutting edge, Quantitative PCR technology to provide a true DNA/PCR based stool test. This technology has high sensitivity, specificity and a rapid turnaround. The GI pathogens include bacteria, parasites and viruses.
Continuing with this platform, the GI-MAP measures opportunistic organisms, normal flora, fungi, parasites and antibiotic resistance genes. And the Plus refers to immunologic markers for GI health and function including SIgA, Elastase, Calprotectin and Anti-gliadin testing.
The GI-MAP can be used in the detection and identification of gastrointestinal microbial nucleic acids and has been clinically validated for the detection of gastrointestinal pathogens that cause infectious colitis or gastroenteritis. It measures a substantial list of opportunistic pathogens as well as a list of FDA-cleared pathogens, including novel targets such as viruses, Microsporidia, and pathogenic virulence factors.
Zonulin is a protein secreted by intestinal cells that regulates intercellular tight junctions which are the connections between epithelial cells that make up the gastrointestinal lining. Zonulin increases intestinal permeability in the jejunum and ileum and is considered a bio-marker for barrier permeability. Tight junctions can be opened or closed, depending on the physiological need. Zonulin’s role is to open tight junctions in the gut. In the case of enteric infections, high zonulin can “open the floodgates” and flush out bacteria and toxins. Certain gut bacteria and gliadin (the main staple protein from wheat) can activate the zonulin system.
