How to read your GI-MAP results

The GI-MAP is the most ordered functional medicine stool test in the United States. Diagnostic Solutions Laboratory uses quantitative PCR to detect and count over 50 organisms across pathogenic bacteria, parasites, viruses, opportunistic overgrowth, and beneficial commensals, plus a panel of host immune and digestive markers (Secretory IgA, Calprotectin, Zonulin, Pancreatic Elastase-1, Beta-glucuronidase). It is heavily used for SIBO, IBS, post-antibiotic dysbiosis, and suspected H. pylori cases. The PDF report is dense (12 to 16 pages depending on add-ons) and is designed to be reviewed by a practitioner, which is why most patients struggle to translate the report on their own.

Methodology Quantitative PCR (qPCR) on a single stool sample.

Sample Single stool sample, collected at home with a kit.

Turnaround 10 to 21 business days

How to order Practitioner-only

Approx. cost $300 to $400 retail; varies by practitioner markup

How GI-MAP works

Quantitative PCR (qPCR) on a single stool sample. qPCR amplifies and counts specific DNA sequences for each target organism, which makes it more sensitive and reproducible than older culture-based tests, and lets the lab report a precise count for each marker rather than a present-or-absent flag.

What GI-MAP does well

Best-in-class H. pylori detection plus virulence factors (CagA, VacA, BabA, DupA)
Quantitative counts for all major opportunistic and pathogenic organisms
Strong host marker panel (sIgA, Calprotectin, Zonulin, Elastase-1, Beta-glucuronidase)
Highly reproducible methodology
Widely accepted across functional medicine and naturopathic practice

What GI-MAP misses

Does not measure short-chain fatty acids (no butyrate, propionate, acetate)
Limited beneficial commensal coverage compared to 16S sequencing tests
Misses organisms not on the targeted qPCR panel (untargeted dysbiosis is invisible)
Reports counts but not full ecological diversity metrics
Has been criticized for low specificity on some opportunistic flags

Frequently asked questions

How much does GI-MAP cost?

Approximately $300 to $400 retail; varies by practitioner markup. The exact price depends on the practitioner who orders it, whether you have insurance reimbursement (most stool tests are not covered), and any add-on panels.

How long do GI-MAP results take?

Typically 10 to 21 business days from the time the lab receives your sample. Add 3 to 5 days for shipping in each direction.

Can I order GI-MAP without a doctor?

Not directly. GI-MAP is sold to practitioners only, so you need a referring doctor, naturopath, dietitian, or licensed practitioner to order it for you. Most functional medicine clinics, telemedicine practitioners, and some integrative gastroenterologists can order it.

Can Test to Table interpret my GI-MAP results?

Yes. Upload your GI-MAP PDF and we will extract every marker, generate a personalized 6-week food protocol with exact quantities, and produce a grocery list.

What does GI-MAP miss?

No single stool test catches everything. The "What this test misses" section above lists the specific gaps. The most common pattern is to combine a targeted-organism test (like GI-MAP) with a diversity-style test (like Biomesight or Thorne) when the clinical question is ambiguous.
