GI Pathogen Test


The GI Pathogen Test looks for the presence of pathogens, bacteria, and fungi, including H Pylori, in the gastrointestinal tract.

Markers on This Test:

  • Bacteria and Toxins (C difficile Toxin A & B, Campylobacter, E coli -157, Salmonella, Shiga Toxins, Shigella, etc.)
  • H pylori (PCR DNA, cagA, vacA, and antigen testing)
  • Parasites (Blastocystis hominis, Entamoeba histolytica, Giardia Lamblia, etc.)
  • Fungi (Candida, etc)
  • GI Health Markers: (Anti-Gliadin IgA, Lactoferrin, Calprotectin, SIgA1 & SIgA2, Fecal Fat)
  • Antibiotic Resistance (by drug class)

To detect pathogens, the lab uses PCR (Polymerase Chain Reaction) technology to detect the DNA of microorganisms. This testing method is far more convenient and accurate than the three day stool samples. Unlike many stool tests which do not allow the use of antibiotics, antimicrobials, bismuth, and other compounds for a couple weeks prior to collecting the samples to avoid interference, the DRG test extracts the DNA of the targeted organism and thus does not require avoidance of any compound.

Test Details:

  • Test Type: Stool (1-day single specimen collection)
  • Instruction Sheet: Download Test Instructions
  • Sample ReportDownload Sample Report
  • Additional info: Specimens must be received by the lab within 7 days of collection. This makes it viable for international clients provided the sample is couriered.
