Another great lab that I can order. Only in the U.S. due to regulations.
The gut microbiome plays a critical role in mediating the effects of diet, digestion, immunity, metabolic function, and more. The GI-MAP (Microbial Assay Plus) test is truly unique in the field, relying exclusively on quantitative polymerase chain reaction (qPCR) technology to detect parasites, bacteria, fungi, and more by targeting their specific DNA, providing quantitative insights to guide more personalized treatment protocols. StoolOMX is a powerful GI-MAP add-on test that evaluates 25 bile acids (total concentrations, percentages, and ratios) and 9 short-chain fatty acids (SCFAs), offering clinicians valuable insights into gut functionality and conditions such as IBS, IBD, bile acid diarrhea, and altered gut motility
Who Should Get the GI‑MAP Test
The GI‑MAP isn’t for everyone, it’s for people whose symptoms or history suggest microbial imbalance, infection, inflammation, or gut‑immune dysfunction.
Here’s the evidence‑based list of who benefits most.
1. People with chronic digestive symptoms
If someone has been dealing with persistent gut issues and standard tests come back “normal,” the GI‑MAP is specifically recommended.
- Chronic bloating
- Constipation or diarrhea
- IBS‑like symptoms
- Abdominal pain
2. People with autoimmune conditions
Autoimmune diseases often have gut‑immune involvement. The GI‑MAP helps identify pathogens, dysbiosis, and inflammation that may be contributing.
Dysbiosis is the disruption in the normal balance, diversity, or function of the gut microbiome that leads to impaired digestion, altered immune signaling, and increased inflammation.
3. People with skin issues
Because the gut-skin axis is real, people with:
- eczema
- acne
- unexplained rashes
- itchy skin
often benefit from identifying microbial triggers or inflammation.
4. People with unexplained fatigue or mood issues
Gut imbalances can influence energy, neurotransmitters, and inflammation.
- chronic fatigue
- mood swings
- anxiety/depression patterns
5. People with suspected infections or dysbiosis
The GI‑MAP is excellent for detecting:
- parasites
- pathogenic bacteria (H. pylori, E. coli, etc.)
- fungi
- viruses
- antibiotic resistance patterns
6. People whose digestion isn’t working properly
If someone has:
- poor nutrient absorption
- low digestive enzymes
- chronic reflux
- undigested food in stool
the GI‑MAP can identify root causes.
7. People who’ve “tried everything” and still feel unwell
This includes those who:
- have normal colonoscopies/endoscopies
- have normal basic stool tests
- have been dismissed with “IBS”
- feel like something is being missed
8. People wanting a root‑cause, functional view of their gut
I use the GI‑MAP to assess:
- dysbiosis
- inflammation
- immune activation
- microbial diversity
- pathogenic load
The gut is the largest immune organ in the body
About 70% of the immune system sits along the intestinal lining.
So when the gut is inflamed, leaky, or imbalanced, the immune system is activated, sometimes chronically.
Chronic immune activation = chronic inflammation = higher risk for:
- metabolic dysfunction
- autoimmune conditions
- skin issues
- mood changes
- fatigue
- hormone disruption
This is why gut dysfunction often shows up years before a diagnosis.
In short:
Anyone with persistent gut, immune, skin, mood, or unexplained systemic symptoms, especially when standard tests are normal, is a strong candidate for the GI‑MAP.
