GI-MAP test: the short version

The GI-MAP (GI Microbial Assay Plus) is an at-home stool panel that uses quantitative real-time PCR (qPCR) for selected microbial genetic targets, including bacteria, parasites, viruses, H. pylori and fungi/yeast. Separate assays measure intestinal-health markers such as calprotectin, secretory IgA and pancreatic elastase. The report includes both numerical and qualitative findings from one sample.

It is run by Diagnostic Solutions Laboratory, a CLIA-certified U.S. lab. Through gimaptest.com you order it online in the United States (a network practitioner places the lab order), collect at home, and receive your results by email. The lab’s standard processing time is 10–16 business days from the date it receives your sample. Once testing is complete and the lab releases your results to us, we typically need an additional 1–3 business days to process and email them to you. Kits start at $525, with free outbound shipping to eligible U.S. states. International and territory shipping is US$50 per physical lab test; see the available destinations and return instructions in our shipping policy.

85+ Biomarkers From a Single Stool Sample

The GI-MAP™ combines quantitative PCR for selected microbial DNA targets with other methods for intestinal-health markers. Results need clinical interpretation; no single stool test is the best choice for every question.

Pathogens & Infections

Detect selected bacterial, parasitic and viral genetic targets. H. pylori virulence-factor findings need clinical interpretation; detection alone does not establish the cause of symptoms.

H. pylori + Virulence Salmonella C. difficile Campylobacter Cryptosporidium Giardia E. coli (EHEC) Norovirus

Microbiome Balance

Quantify beneficial, opportunistic, and commensal bacteria to assess microbiome composition and balance patterns.

Lactobacillus Bifidobacterium Akkermansia Candida spp. Enterococcus Desulfovibrio Roseburia Faecalibacterium

Intestinal Health Markers

Separate assays report markers related to inflammation, immune response and digestion. These findings need clinical interpretation and do not select a treatment on their own.

Calprotectin Secretory IgA Elastase-1 Steatocrit β-Glucuronidase Occult Blood Anti-gliadin IgA Zonulin (add-on)

What is the GI-MAP test?

The GI-MAP — short for GI Microbial Assay Plus — is a comprehensive DNA-based stool analysis from Diagnostic Solutions Laboratory. It uses quantitative real-time PCR (qPCR) to detect selected microbial genetic targets, alongside separate assays for intestinal-health markers. Some findings are numerical and others are qualitative. From one sample it reports:

  • Pathogenic bacteria, parasites and viruses
  • Helicobacter pylori with its virulence factors
  • Fungi and yeast such as Candida
  • Selected commensal and opportunistic microbial targets
  • Intestinal-health markers related to inflammation, immune response and digestion

Why qPCR and quantitative results matter

qPCR measures selected microbial genetic targets in the submitted sample. It does not measure every organism, and a detected genetic target does not by itself establish that a viable organism is present. GI-MAP also includes qualitative results and separate intestinal-health assays.

Clinical interpretation depends on symptoms, history, the assay and the reason for testing. A change on repeat testing does not, on its own, confirm treatment success; ask whether repeating the panel would answer a useful clinical question.

Add-ons that extend the GI-MAP

Most entries in the explorer are in the standard panel; zonulin is an optional add-on. Diagnostic Solutions Laboratory also offers a few optional markers for an additional fee. Of those, Zonulin is currently the only one you can order through us — the others have to be requested from the laboratory by your practitioner.

Available here

Zonulin

An optional stool immunoassay. The laboratory describes fecal zonulin as investigational; a result does not by itself diagnose increased intestinal permeability or explain symptoms. Review the limitations with a licensed clinician before choosing this add-on. GI-MAP™ + Zonulin →

Lab add-on · not sold here yet

Fecal Gluten Peptide

Detects the 33-mer gliadin immunogenic peptide, which resists digestion and shows up in stool roughly two to four days after gluten is eaten — an objective check on recent or hidden gluten exposure. Ordered from the laboratory for an extra fee; we do not carry it as a product yet.

Lab add-on · not sold here yet

Universal Antibiotic Resistance Genes

Screens the sample for 55 resistance genes spanning 10 classes of common antibiotics across the whole microbiome. Ordered from the laboratory for an extra fee; we do not carry it as a product yet.

Lab add-on · not sold here yet

StoolOMX

Measures 25 bile acids and 9 short-chain and branched-chain fatty acids by LC-MS/MS — microbial metabolites that reflect how your microbiome is functioning, not just who is present. Ordered from the laboratory for an extra fee; we do not carry it as a product yet.

Two things people mix up

Antibiotic-resistance genes. The standard panel already reports resistance genes and virulence factors — but only for H. pylori, and only when it is detected. The Universal panel above is a separate, broader screen across the whole gut.

Gluten markers. Anti-gliadin sIgA in the panel above is an antibody response and is included as standard. The Fecal Gluten Peptide add-on is different — it detects gluten fragments themselves.

Panel contents, add-on availability and pricing are set by Diagnostic Solutions Laboratory and may change.

Who considers a GI-MAP test?

People and practitioners commonly use the GI-MAP when gut symptoms are unexplained, persistent, or affecting the rest of the body. It is a testing tool, not a diagnosis — we recommend reviewing your results with a licensed practitioner in the context of your history.

IBS & digestive complaints

Bloating, gas, diarrhea, constipation, reflux and abdominal pain that standard work-ups haven't explained.

Suspected infections

Possible parasites, H. pylori, bacterial overgrowth or yeast — with quantification and, for H. pylori, virulence and resistance genes. H. pylori guide →

IBD-related monitoring

Calprotectin, a marker of intestinal inflammation, helps a clinician distinguish inflammatory from functional bowel patterns.

Autoimmune & leaky gut

A stool zonulin result does not, by itself, diagnose increased intestinal permeability or explain symptoms. Signs of leaky gut →

Skin & mood

Skin flare-ups and mood changes are often explored through the gut-skin and gut-brain connections.

Metabolic & weight

Microbiome composition, including phyla ratios, is studied in relation to metabolic and weight status.

Gut-brain axis

The microbiota-gut-brain axis links gut microbes with stress, mood and cognition — increasingly a reason people test.

Autoimmune terrain

Several gut organisms are studied in autoimmune conditions. Gut health & autoimmunity →

Browse all conditions & how the GI-MAP fits in →

Quantitative results you can re-test

A numerical change and a clinical improvement are different outcomes. Repeating a marker should address a defined clinical question.

A clinician can decide whether to repeat the same marker, use a different test or investigate another cause of symptoms. The timing and usefulness of follow-up depend on the finding and the clinical context; a flagged number alone does not establish a need for another full panel.

GI-MAP™ reports selected microbial genetic targets and intestinal-health markers. These findings may contribute to a clinical assessment, but a positive finding or laboratory flag does not by itself diagnose a condition or establish the cause of symptoms. Discuss the clinical question with a licensed clinician when choosing a test.

A G.I. MAP test — also called the GI-MAP™ (GI Microbial Assay Plus) — is a stool panel from Diagnostic Solutions Laboratory. It uses qPCR for selected microbial genetic targets and separate assays for intestinal-health markers from an at-home stool sample.

Yes. When people search for a "GI mapping test," they are typically referring to the GI-MAP™ by Diagnostic Solutions Laboratory. The panel uses qPCR for selected microbial genetic targets and separate assays for intestinal-health markers. It does not map every organism in the gut or establish an infection from detection alone.

All three are comprehensive stool panels, but they use different technology. The GI-MAP™ is a panel combining quantitative PCR for microbial targets with other assays for intestinal-health markers from a single stool sample, and it reports H. pylori with eight virulence-factor targets. Genova's GI Effects combines qPCR, culture, microscopy and stool chemistry, with one- or three-day collection options. Doctor's Data GI360 combines PCR, culture with MALDI-TOF identification, microscopy and stool chemistry; follow the collection instructions for the ordered profile. Your practitioner selects the panel that best fits what they need to assess. See our full comparison table above.

Your GI-MAP™ report groups results by category — pathogens, H. pylori, normal/commensal flora, opportunistic organisms, fungi, parasites, and intestinal-health markers — and includes numerical values alongside qualitative findings such as detected, not detected or not applicable. Use the units and reference information on your own report. Because the report is detailed and clinical, we recommend reviewing your results with a licensed practitioner who can interpret the findings in your clinical context. You can preview the layout on our sample report page.

Stop Guessing. Start Testing.
