Gut issues for years, multiple doctors, no real answers. HFW's testing actually looked at things nobody else checked.
Home › Advanced Health Tests › GI-MAP Test
The GI-MAP is an at-home stool test from Diagnostic Solutions Laboratory. It uses DNA-based testing to measure pathogens, H. pylori, the balance of gut bacteria, digestion, inflammation and gut immune markers. Your clinician reads every result with you.

The short answer
A clinician-ordered stool test that measures about 180 bacterial species plus parasites, yeast and viruses, along with markers of digestion, gut inflammation and the gut barrier. It is collected at home. At HFW it costs $813, including a 60 to 90 minute clinician review and a plan for what to correct first.

If digestion, the gut barrier or gut inflammation is strained, even a well-chosen therapy can underperform. Results often decide whether we correct the gut first or work on it alongside other priorities.
Detecting an organism or marker does not by itself prove it is causing symptoms or needs treatment.

Questions
Bacteria, parasites, yeast and viruses including H. pylori, the balance of beneficial and harmful bacteria, digestion and fat absorption, gut inflammation and gut immune markers like secretory IgA and zonulin.
At home, from a single stool sample, using the kit HFW sends you. Your clinician will tell you if anything should be paused before you collect.
Not always. Detecting an organism or marker does not by itself prove it is causing your symptoms. Your clinician reads the results alongside your symptoms and history before recommending anything.
No. The GI-MAP is ordered and interpreted by a clinician and uses quantitative DNA testing for specific organisms and markers, rather than a consumer report on its own.
