GI-MAP Test: What to Expect
What it measures
The GI-MAP is a stool test that uses qPCR DNA technology to measure gut organisms — bacteria, parasites, viruses, and fungi — along with markers related to digestion, immune activity, and gut inflammation. Practitioners use it to investigate digestive symptoms and overall gut health.
How collection typically works
It's a single stool sample. Kits include a collection tray or paper that sits across the toilet so the sample never touches water, a small vial with a preservative liquid and an attached scoop, and a return mailer. You transfer the specified small amount into the vial, secure and shake it per the instructions, complete the paperwork or online registration, and ship it back — most kits ask for same-day or next-day shipping, avoiding weekend drop-offs so the sample doesn't sit in transit.
Preparation notes
Timing flexibility is one of this test's advantages — there's no fasting or special diet in most cases. Practitioners sometimes advise spacing the test away from antibiotics, antimicrobial herbs, or certain other products so results reflect your baseline; whoever ordered your test can tell you what applies to you.
