More comprehensive than the GI-MAP.
This at-home stool test from US Biotek is the most advanced way to assess your digestive health and microbiome. With 127+ markers across 15 categories, it surpasses basic and standard stool panels by combining PCR and microbial culture for unmatched accuracy.
If you want the complete picture of gut health — including pathogens, parasites, fungi, autoimmune triggers, and digestive function — this test leaves nothing out.
What’s Included:
7 Key Phyla % commensal abundance
17 Parasites & worms
15 Opportunistic bacteria
8 Potential autoimmune triggers
14 Fungi & yeasts
14 Bacterial pathogens
5 Viral pathogens
17 Normal flora markers
4 Macroscopy
5 Short-chain fatty acids
8 GI functional markers (calprotectin, pancreatic elastase, secretory IgA, zonulin, β-glucuronidase, steatocrit, transglutaminase IgA)
2 Microbial culture alongside PCR (dual method for accuracy)
4 Antimicrobial sensitivities
Why It Matters:
Detects gut pathogens, parasites, and fungi that standard tests miss
Evaluates digestive and inflammatory markers (zonulin, calprotectin, elastase) linked to leaky gut, IBD, and autoimmune risk
Screens for viral and bacterial triggers tied to chronic illness
Provides a detailed map of commensal, opportunistic, and pathogenic microbes
Dual-method (PCR + culture) increases accuracy over PCR-only tests like GI-MAP
May Be Helpful For:
IBS, bloating, constipation, diarrhea, or unexplained GI distress
Fatigue, brain fog, or mood concerns linked to gut imbalance
Autoimmune or inflammatory conditions
Food intolerances, leaky gut, or chronic inflammation
Recurrent infections, parasites, or yeast overgrowth
Why Choose This Test Over the GI-MAP?
GI-MAP uses PCR only and covers fewer categories.
GI Advanced Profile = 127+ markers, dual-method (PCR + culture), includes zonulin and short-chain fatty acids, and screens for viral pathogens.
In short: if you want the most complete gut analysis available, this is it.

These functional lab tests are designed to provide meaningful insights into your health and support greater awareness of potential imbalances. While they can be a powerful tool for wellness exploration, they are not a substitute for medical diagnosis, treatment, or care. Purchasing a lab test does not establish a doctor-patient relationship. Personalized interpretation and health recommendations are available through a separately scheduled consultation. If you reside in Oregon or Washington and wish to establish medical care, you may do so through a Comprehensive New Patient Appointment via the Book Now link. For all other medical needs, please consult your personal healthcare provider.
