In recent years, gut health has taken center stage in the world of wellness and medicine. As science continues to uncover the profound connections between the gut microbiome and everything from immunity to mental health, more people are turning to advanced diagnostic tools to get a clearer picture of what’s happening inside their digestive systems. One such tool is the GI-MAP test — a cutting-edge stool analysis that offers valuable insights into your gut microbiome and digestive health.
What Is the GI-MAP Test?
GI-MAP stands for Gastrointestinal Microbial Assay Plus. It is a comprehensive stool test developed by Diagnostic Solutions Laboratory that uses quantitative polymerase chain reaction (qPCR) technology — a highly sensitive and specific method for detecting DNA — to identify and measure a wide range of microbes in the gut.
Unlike traditional stool tests, which may only offer qualitative insights (i.e., presence or absence), the GI-MAP provides quantitative data. This means it tells you not just what microbes are present, but how many, which can help determine if imbalances in the microbiome are contributing to how you feel.
What Does the GI-MAP Test For?
The GI-MAP test screens for a wide array of markers, including:
Bacterial pathogens (e.g., Clostridium difficile, Salmonella)
Parasitic pathogens (e.g., Giardia, Blastocystis hominis)
Viral pathogens (e.g., Norovirus, Rotavirus)
Commensal (normal) bacteria — evaluates the balance of beneficial microbes
Fungal organisms, such as Candida
Intestinal health markers, including:
Secretory IgA (immune function)
Calprotectin (inflammation)
Zonulin (intestinal permeability, aka “leaky gut”)
Beta-glucuronidase (a marker associated with detoxification)
Why Take a GI-MAP Test?
This test can be useful for people dealing with a wide range of chronic or unexplained symptoms, such as:
Bloating and gas
IBS or IBD symptoms
Chronic diarrhea or constipation
Fatigue or brain fog
Skin issues like eczema or acne
Autoimmune conditions
Hormonal imbalances
Food sensitivities
Because the gut plays such a pivotal role in overall health, identifying imbalances or infections in the microbiome can often uncover the root cause of persistent health issues.
How Is the GI-MAP Test Done?
The test is non-invasive and done at home. Here's how it works:
You receive a test kit with instructions.
You collect a stool sample in the comfort of your home.
You send it to the lab using the prepaid shipping materials provided.
Your healthcare provider receives the results in about 2–3 weeks and can interpret them alongside your symptoms.
What Makes the GI-MAP Unique?
Quantitative data for clinical relevance
FDA-approved DNA extraction method
High sensitivity to low-abundance organisms
Comprehensive gut marker panel
Backed by clinical research and used by integrative and functional medicine practitioners worldwide
What Happens After the Test?
Once your results are in, our team will help you interpret the data. Based on your specific microbial balance and health markers, we may recommend:
Dietary changes (e.g., eliminating trigger foods, increasing fiber)
Targeted supplements (e.g., probiotics, antimicrobials, enzymes)
Lifestyle interventions (e.g., stress management, sleep support)
The goal is not just to eliminate pathogens but to restore balance and optimize your gut environment.
Final Thoughts
The GI-MAP test is a powerful tool for anyone looking to take control of their digestive and overall health. Whether you're struggling with chronic symptoms or simply want to optimize wellness, this test can offer a deeper understanding of what’s happening in your gut and guide you toward targeted, personalized treatment strategies.
