Functional Lab Testing

Gut Health Test / Functional Medicine Testing / Functional Lab Testing

A gut health test like the GI MAP helps to identify contributing factors to why you may be experiencing obvious GI symptoms as well as seemingly unrelated symptoms. Read more about GI Map test results here (or see a potion of my personal results here). Additional functional medicine testing like the DUTCH test, Vibrant Wellness Zoomer testing and the OATS test can expose other triggers or imbalances that might be contributing to unpleasant or debilitating symptoms as well. The reason we use functional lab testing when appropriate, is to help us get an overall picture of what’s going on inside the body that’s contributing to your specific imbalances so we have a starting place to work from without guessing. See below for a list of the most common tests used.


The Diagnostic Solutions Laboratory GI Microbial Assay Plus (“GI-MAP”) a 1-day stool test includes markers for gluten sensitivity (anti-gliadin IgA), inflammation in the gut (calprotectin), immunity in the gut (SIgA), pancreatic enzyme sufficiency (elastase), and occult blood. It also looks for the presence of pathogens – including H Pylori and other bacteria, parasites, worms and viruses – in the gastrointestinal tract. To detect pathogens, the lab uses Real-time polymerase chain reaction (RT-PCR), or quantitative PCR (qPCR), which combines amplification and detection into one step. qPCR “is one of the most powerful and sensitive gene analysis techniques available to detect the DNA of microorganisms.


  • Bacterial Pathogens (Campylobacter, C difficile Toxin A & B, EHEC, E coli 0157, EIEC/Shigella, ETEC LT/ST, Salmonella, Shiga-like Toxins, Shigella, etc.)

  • Normal Bacterial Flora (Bacteroides Fragilis, Bifidobacter, Enterococcus, E. coli, Lactobacillus, Clostridium Spp., Enterobacter Spp.)
  • Phyla Microbiota (Bacteroidetes, Firmicutes, Bateroidetes/Firmicutes ratio)

  • Autoimmune Triggers (Citrobacter, Klebsiella, Mycobacterium tuberculosis, Prevotella Copri, Proteus Spp etc)
  • Parasites (Blastocystis hominis, Dientamoeba fragilis, Endolimax nana, Entamoeba coli, Chilomastix mesnelli, Cyclospora, Pentatrichomonas)
  • Fungi/Yeast (Candida albicans, Candida spp., Geotricum spp., Microsporidia spp., Rodotorula spp.)
  • Viruses (Cytomegalovirus, Epstein Barr Virus)

  • Additional Tests (Elastase, Steatocrit, SIgA, Anti-Gliadin, Calprotectin, b-Glucuronidase, Occult Blood)
  • Antibiotic Resistance Genes

DUTCH Complete Hormone Test—DUTCH Adrenals + DUTCH Hormone Metabolites Profiles + Melatonin

This test provides you with detailed information on how adrenal and sex hormones are being produced AND metabolized in the body. DUTCH stands for Dried Urine Test for Comprehensive Hormones.

The DUTCH Complete now includes the following additional markers:

  • Homovanillate (HVA) – the primary dopamine metabolite
  • Vanilmandelate (VMA) – the primary norepinephrine and epinephrine metabolite
  • 5-hydroxyindoleacetate (5HIAA) – the primary serotonin metabolite
  • Methylmalonate (MMA) – elevated if patients are vitamin B12 deficient
  • Xanthurenate – elevated if patients are vitamin B6 deficient
  • Pyroglutamate – elevated if patients are glutathione deficient

OAT—Urine Organic Acids Testing:

This urine test provides insight into the body’s cellular metabolic processes. Organic acids are metabolic intermediates that are produced in pathways of central energy production, detoxification, neurotransmitter breakdown, or intestinal microbial activity. Marked accumulation of specific organic acids detected in urine often signals a metabolic inhibition or block. The metabolic block may be due to a nutrient deficiency, an inherited enzyme deficit, toxic build-up or drug effect. Several of the biomarkers are markers of intestinal bacterial or yeast overgrowth.

Vibrant Wellness Wheat Zoomer:

The Vibrant Wellness Wheat Zoomer Test is designed to be the most exhaustive coverage of the wheat proteome.
