If you’ve been struggling with chronic bloating, digestive discomfort, unexplained fatigue, or persistent skin issues, your gut could be the missing piece of the puzzle. GI-MAP functional stool testing is designed to provide a comprehensive look at the microbes, pathogens, and imbalances that may be leading to your symptoms.
What is GI-MAP Functional Stool Testing?
The Gastrointestinal Microbial Assay Plus, or GI-MAP, is an advanced stool test that analyzes your gut microbiome using DNA-based technology. Unlike traditional stool tests, which rely on culturing bacteria, GI-MAP uses quantitative PCR (qPCR) to detect the DNA of various microorganisms, making it highly accurate and sensitive.
This test assesses:
- Beneficial bacteria that support digestion and immunity
- Opportunistic bacteria that can cause dysbiosis
- Pathogens including parasites, viruses, and harmful bacteria
- Fungal overgrowths such as Candida
- Digestive function markers like pancreatic elastase and steatocrit to assess fat malabsorption
- Inflammation markers such as calprotectin (linked to gut inflammation and leaky gut)
- Immune response through secretory IgA levels
How Does the GI-MAP Test Work?
The idea of collecting a stool sample to be tested can be a little out there, so here’s what you can expect:
1. Collect a sample – A stool sample is collected at home using a provided kit and then shipped to a specialized lab. Literally everything you need to collect a sample easily and cleanly is included in the test kit. It is a much simpler and easier process than clients make it out to be in their heads. You also get instructions sent to you before you receive your test kit, so you can get an idea of what to expect and be prepared when your test kit arrives.
2. Send off to the lab – Once you collect your sample, you mail it off (yes, you send your poop out in the mail in included, secured, biohazard packaging). The lab then uses qPCR technology to analyze the sample for microbial balance, digestive function, and inflammatory markers.
3. Receive results – The lab will send me your results in about 1-2 weeks. The results provide detailed insights into gut health, highlighting imbalances that may contribute to symptoms that can then be interpreted in light of your intake data and symptoms.
4. Get personalized recommendations – Based on the findings, a functional nutrition practitioner can create a customized plan, including diet, lifestyle, and targeted supplements to restore gut balance.
Common Questions About GI-MAP Testing
I get asked a number of questions regarding this slightly unusual test, so here are answers to the ones I most commonly receive regarding GI-MAP functional stool testing.
1. What makes GI-MAP functional stool testing different from a colonoscopy?
A colonoscopy is a medical procedure that provides a visual examination of the colon via a camera that is inserted via a tube into the large intestine. It can detect polyps, tumors, ulcers, inflammation, and other structural abnormalities in the intestinal lining. It is helpful to screen for cancer and investigate sources of intestinal bleeding, such as in cases of Irritable Bowel Disease. A colonoscopy is completed in a medical office and requires at home prep.
A functional stool test, specifically the GI MAP, analyzes the contents of your stool to assess the balance of bacteria in the gut microbiome, as well as pathogens, parasites, yeast, fungus, viruses, and inflammation. The GI MAP uses polymerase chain reaction technology to detect the DNA of these microorganisms, helping to identify gut dysbiosis, intestinal permeability, enzyme function, and immune response. It is helpful for detecting and treating chronic digestive issues, such as IBS, SIBO, autoimmune conditions, hormone imbalances, chronic fatigue, and weight loss resistance. A GI MAP can be completed at home at any time.
2. Why choose GI-MAP over other stool tests?
All functional stool tests have pros and cons that set them apart from other comparable tests. The GI-MAP offers greater sensitivity and accuracy compared to traditional stool tests. Because it detects microbial DNA, it can identify low-level infections or imbalances that may not appear in culture-based tests. I have found GI-MAP results to be aligned with reported client symptoms, allowing for tailored treatment to be effective quickly.
3. What symptoms can GI-MAP help identify the root cause of?
GI-MAP is beneficial for those experiencing:
- Chronic bloating, gas, constipation, or diarrhea
- Heartburn, acid reflux, or indigestion
- IBS and IBD symptoms
- Food sensitivities
- Autoimmune conditions
- Skin issues like acne or eczema
- Brain fog and fatigue
- Joint and muscle pain
- Mystery ailments and unidentified inflammation
- Hormonal imbalances
4. Can GI-MAP detect parasites?
Yes! GI-MAP can identify a variety of parasites, including Giardia, Cryptosporidium, and Blastocystis hominis, which can be overlooked in standard stool tests.
5. How do I know if I need a GI-MAP test?
If you’ve tried addressing gut symptoms with fiber supplements and probiotics but aren’t seeing lasting improvements, GI-MAP functional stool testing can provide additional insights into underlying imbalances that need targeted support.
6. How often should I retest?
Depending on your symptoms, results and treatment plan, taking a new GI-MAP every 4-12 months can be beneficial.
How I Do Functional Stool Testing Differently
This is not the place to get cookie cutter protocols. I do not have a standard answer for addressing candida or dysbiosis or low stomach acid. Every single protocol recommendation I put together is personalized to your data in combination with your health history, your main concerns, and your ideal outcomes. GI-MAP functional stool testing is a tool to help us get to the root cause, but it is not the sole determinant of what treatment plan I recommend.
Getting Started With GI-MAP Functional Stool Testing
GI-MAP functional stool testing is an invaluable tool for uncovering hidden gut imbalances and guiding a personalized approach to feeling better. Whether you’re dealing with stubborn digestive issues, unexplained symptoms, or simply want to optimize your gut health, this test can provide the answers you need to feel your best.
