The GI-MAP™ Standard panel plus an optional stool zonulin measurement. A fecal zonulin result does not independently diagnose intestinal permeability.
Practitioner review: optional, +$245. Not included.
- Everything in Standard — pathogens, bacteria, parasites, fungi, viruses & digestion markers
- + Zonulin — a stool marker requiring clinical interpretation
- qPCR DNA technology — analysis of selected microbial DNA targets
- Lab: 10–16 business days from receipt; email: an additional 1–3 business days after lab release
86 biomarkers from a single at-home sample
The complete GI-MAP™ panel plus an optional stool zonulin measurement. Microbial DNA targets and other intestinal-health markers use different laboratory methods.

Pathogens & opportunists
Bacterial, parasitic, viral and fungal pathogens — quantified, not just detected.
Microbiome balance
Beneficial and opportunistic flora that shape digestion, immunity and mood.
Intestinal health markers
Inflammation, immune response, digestion and absorption — the function behind the flora.
Zonulin — the optional stool marker
Included in this package, but not in Standard. Stool zonulin is not a validated stand-alone test of intestinal permeability (sometimes called "leaky gut").
Why add Zonulin?
Zonulin is the protein that regulates the tight junctions between the cells lining your gut. When those junctions loosen, the barrier becomes more permeable — often called "leaky gut."
The added stool zonulin result is not a definitive readout of gut-barrier integrity and cannot diagnose a food sensitivity or autoimmune disease. The laboratory's 2025 technical white paper describes fecal zonulin testing as investigational; independent research has raised concerns about the specificity of some commercial assays. A qualified practitioner can help determine whether this result adds value to your care.
Evidence: Diagnostic Solutions Laboratory GI-MAP white paper (2025); independent zonulin assay limitations research.
From your door to your results in 4 steps
Order online
Your kit includes the materials for home collection. Outbound shipping is free to eligible US states; international and territory shipping is US$50 per physical lab test.
Collect your sample
After payment, complete one intake per person before the practitioner places the lab order. A test and its purchased review use the same form. Collect your sample following the laboratory instructions supplied with your kit.
Return the sample
Use the return instructions supplied for your country and test. Prepaid returns are available in most eligible U.S. locations. Review the shipping policy for exclusions.
Get your results
Lab processing: 10–16 business days from sample receipt, plus an additional 1–3 business days after lab release for us to process and email your results.
A clear, color-coded results report
The report presents laboratory measurements and reference ranges for discussion with your healthcare professional. Results alone do not establish a diagnosis or treatment plan.
Different tests answer different questions
GI-MAP uses qPCR for selected microbial targets and includes intestinal-health markers measured by other laboratory methods. Discuss which tests are appropriate for your symptoms with a qualified healthcare professional. GI-MAP does not replace other testing when indicated.
GI-MAP™ + Zonulin — common questions
It includes the complete Standard panel and one added fecal zonulin measurement. Because that result cannot independently diagnose intestinal permeability or the cause of symptoms, consider your clinical question and discuss the optional marker with a qualified practitioner.
The add-on supplies a fecal zonulin result not present in Standard. Its clinical utility and assay interpretation have important limitations, so ask a qualified practitioner whether it is likely to change decisions made about your care.
The zonulin version is the full GI-MAP™ panel plus the gut-barrier marker, so it is priced above the standard panel. The current price is shown in the order panel at the top of this page, and every GI-MAP™ price sits side by side on our GI-MAP test pricing page, including what each one covers and what it does not.
It's a simple at-home stool collection — everything you need is in the kit, with return packaging and instructions for your country and test. No clinic visit or appointment required.
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.
Before you order, check whether the GI-MAP™ is covered by insurance or read about paying with HSA or FSA.
