GI Map Testing (In-Home Stool Test)

DNA-Based Comprehensive Gastrointestinal Microbiome Assay

The GI-MAP (Gastrointestinal Microbial Assay Plus) is one of the most advanced, DNA-based functional stool tests available in clinical medicine. Utilizing quantitative polymerase chain reaction (qPCR) technology, this test analyzes the genomic DNA of your gastrointestinal microbiome to evaluate microbial balance, detect pathogenic infections, assess gut inflammation, and measure digestive enzyme function.

Key Areas Evaluated by GI-MAP:

• Bacterial Pathogens & Parasites: Detects acute and chronic pathogens including H. pylori (and virulence factors), Campylobacter, C. difficile, Giardia, and Blastocystis hominis.
• Fungal & Yeast Overgrowth: Accurately quantifies Candida albicans, Candida species, and microsporidia.
• Opportunistic & Dysbiotic Bacteria: Evaluates overgrowth of inflammatory and autoimmune-triggering bacteria (including Klebsiella, Pseudomonas, and Citrobacter).
• Beneficial Phyla & Commensal Flora: Quantifies protective keystone bacteria including Akkermansia muciniphila, Bifidobacterium, and Lactobacillus.
• Functional GI Biomarkers:
  • Calprotectin: Measures intestinal mucosal inflammation and immune activation.
  • Secretory IgA (sIgA): Assesses mucosal immunity and gut barrier defense.
  • Elastase-1: Evaluates pancreatic exocrine digestive enzyme output.
  • Beta-Glucuronidase: Measures bacterial enzyme activity impacting estrogen detoxification.
  • Occult Blood: Screens for microscopic gastrointestinal bleeding.
