What it measures

Optional add-ons offered by many sellers include zonulin.

Zonulin add-on: one peer-reviewed study (Scheffler et al., Frontiers in Endocrinology, 2018) found that a widely used commercial serum zonulin ELISA did not detect pre-haptoglobin 2 (the protein identified as zonulin) and instead recognized other proteins. That study examined a serum kit; it does not necessarily describe the stool assay used on GI-MAP. Source: https://doi.org/10.3389/fendo.2018.00022

FAQ
Do I need a doctor's order to buy a GI-MAP?
Many sellers listed here include an authorizing practitioner in the price or partner with one; some practitioner storefronts and clinics sell only to their own patients. Check the 'Who can order' column and each seller's page.
Why do GI-MAP prices vary so much?
Sellers bundle different things: some include a results review or consult, some charge separate physician or handling fees, and some are clinics selling at a patient price. The lab analysis itself is the same GI-MAP panel.
Is the zonulin add-on included?
Usually not. The prices on this page are for the standard GI-MAP unless the row notes otherwise.
Why do prices differ so much?
Sellers set their own prices for the same lab's kit and may bundle practitioner authorization, consultations, shipping or add-ons. The table shows the price and any separately listed fees as posted on each seller's public page on the date checked.
How current are these prices?
All prices were checked on Oct 19, 2026. Prices and availability (including state restrictions) change; confirm on the seller's page before ordering.
