- Everything in Standard — pathogens, bacteria, parasites, fungi, viruses & digestion markers
- + Zonulin — a direct read on gut-barrier integrity / intestinal permeability
- qPCR DNA technology — the functional-medicine gold standard
- Practitioner-ordered & reviewed — results in 10–14 business days
86 biomarkers from a single at-home sample
The complete GI-MAP™ panel plus the Zonulin gut-barrier marker — quantified with DNA-level precision.
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 gut-barrier marker
Exclusive to this package. A direct measure of intestinal permeability ("leaky gut") that the Standard panel doesn't include.
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."
Measuring zonulin gives your practitioner a direct read on gut-barrier integrity — context that's especially useful when investigating intestinal permeability, autoimmune patterns, or unexplained food sensitivities. It's the one marker the Standard panel doesn't include.

How it compares to a basic stool test
Trusted by people taking back their gut health
"After years of bloating and no answers, the GI-MAP finally gave my practitioner something concrete to work with. The Zonulin result explained so much."
"The whole thing was painless — kit arrived fast, collection was simple, and the report was genuinely easy to understand with my provider."
"Worth every penny. Adding Zonulin was the right call for me — it's the detail that shaped my whole protocol."
GI-MAP™ + Zonulin — common questions
It's the most complete profile available — the full 85+ biomarker panel plus a direct gut-barrier measurement. Most practitioners recommend it for first-time testing or anyone investigating leaky gut, autoimmune patterns, or food sensitivities.
If you suspect intestinal permeability, have autoimmune concerns, or experience unexplained food sensitivities, Zonulin provides data the Standard panel doesn't — a direct read on gut-barrier integrity that often shapes the protocol.
It's a simple at-home stool collection — everything you need is in the kit, with a prepaid return mailer. No clinic visit or appointment required.
Typically 10–14 business days after the lab receives your sample. Your report is reviewed with practitioner guidance before it reaches you.
