When it comes to uncovering the root causes of chronic issues, traditional lab work often doesn’t give the full picture. Advanced stool testing — such as the GI Map Test and the GI 360 Test — make all the difference.
Both tests are powerful tools in functional medicine because they don’t just look at symptoms. They reveal what’s really happening inside your gut microbiome, and how that might be impacting your overall health.
Understanding the GI Map Test
The GI Map Test (Gastrointestinal Microbial Assay Plus) uses advanced DNA analysis to identify microbes in your stool. This includes:
- Bacteria (beneficial and pathogenic)
- Parasites
- Viruses
- Fungi and yeast
But what makes the GI Map unique is that it goes beyond listing microorganisms. It also measures markers of inflammation, digestion, immune response, and intestinal health.
For example, it can reveal whether your gut is inflamed, your digestion impaired, or your immune system overactive. This plays a role in issues like IBS, autoimmune conditions, skin problems, or even mood imbalances.
What About the GI 360 Test?

The GI 360 Test is another advanced stool test, developed by Doctor’s Data. It uses PCR technology and culture methods to provide a broad view of the gut microbiome.
Key features of the GI 360 include:
- Comprehensive mapping of bacterial diversity
- Detection of pathogens linked to chronic illness
- Identification of dysbiosis (imbalances between good and harmful bacteria)
- Insights into metabolic health and inflammation markers
This test is especially useful for patients dealing with chronic digestive problems, unexplained inflammation, or conditions suspected to be linked to gut imbalance.
GI Map Test vs. GI 360: Which One Should You Choose?
Both tests provide valuable information, but there are some distinctions:
- GI Map Test: Often favored in functional medicine because of its detailed markers on inflammation, immune activity, and digestive function, alongside microbial DNA analysis.
- GI 360 Test: Provides a broader overview of microbial diversity and is excellent for assessing overall microbiome balance and identifying dysbiosis patterns.
Functional medicine practitioners may choose one or the other depending on the patient’s symptoms and medical history.
Why Functional Medicine Uses These Tests
Functional medicine looks for the root cause of illness rather than masking symptoms. Because the gut is central to many systems in the body having precise data on gut health with GI Map test can completely change the course of treatment.
These tests allow practitioners to:
- Personalize nutrition and supplementation
- Target microbial imbalances with precision
- Reduce inflammation and support immune balance
- Create a long-term plan for optimal gut health
Conclusion
Whether it’s the GI Map Test or the GI 360 Test, advanced stool testing offers critical insights that help uncover hidden drivers of chronic health issues. From digestive discomfort to autoimmune conditions, these tools provide the foundation for a personalized healing plan.
