Looking for gut, stool, or microbiome testing in Houston? The GI-MAP™ (Gastrointestinal Microbial Assay Plus) brings clinical-grade stool analysis to your door — no lab appointment, no clinic waiting room. It uses quantitative PCR (qPCR) DNA technology to detect and quantify 85+ markers from a single at-home sample: bacterial and parasitic pathogens, H. pylori with virulence factors, fungi, beneficial flora, and intestinal-health markers. Kits ship free to Houston and across Texas, with results in 10–14 business days.

- Collect at home. Your kit ships free to Houston. Collect a small stool sample and mail it back in the prepaid return mailer.

A medical city with a growing functional-medicine community
Home to the Texas Medical Center, the world’s largest medical complex, Houston is deeply health-literate — and its integrative and functional-medicine community has grown alongside it. Houstonians looking beyond a routine stool test for chronic digestive issues use the GI-MAP’s 85+ marker panel for a fuller view, all from an at-home kit shipped across the metro.
What the GI-MAP screens for
Whether you searched for “stool testing,” “microbiome testing,” or “GI pathogen screening” near Houston, the GI-MAP covers it in one panel — screening for parasites (including Giardia, Cryptosporidium and other parasites), bacterial pathogens like Salmonella and C. difficile, H. pylori, fungi, and gut-health markers such as calprotectin and secretory IgA.
