5GI Map Gut Microbiome Test for Root-Cause Gut Health Insights in Singapore
Your gut sits at the centre of almost everything: digestion, immunity, hormones, mood, energy, skin, even sleep. When the microbial balance is off, the symptoms often spread far beyond the digestive tract, showing up as IBS, eczema, autoimmune flares, brain fog, fatigue, anxiety, and stubborn weight. Standard stool tests only check for a handful of obvious pathogens and miss the subtler imbalances that quietly drive chronic illness for years.
At NutraNourish, we use the GI-MAP Test (Gastrointestinal Microbial Assay Plus), the most comprehensive DNA-based gut microbiome test available. Using quantitative PCR (qPCR) technology, the GI-MAP detects bacterial, parasitic, fungal, and viral DNA directly from a single at-home stool sample, identifying pathogens, opportunistic organisms, beneficial bacteria, inflammation markers, immune function, and intestinal barrier integrity in a single panel. The test is processed by Diagnostic Solutions Laboratory in the USA (the lab that developed the GI-MAP), and your report is interpreted by Dr. Menka Gupta and turned into a personalised gut reset program addressing the root cause, not just the symptoms.

What is a GI-MAP Test?
The GI-MAP short for Gastrointestinal Microbial Assay Plus is the very comprehensive stool test currently available, using DNA-based qPCR (quantitative polymerase chain reaction) technology to give you a complete picture of what’s actually living in your gut. The GI-MAP detects bacterial, parasitic, fungal, and viral DNA directly meaning it picks up pathogens and imbalances that traditional tests routinely miss.
This matters because chronic health issues IBS, eczema, autoimmune flares, brain fog, fatigue, hormonal imbalance traces back to a imbalances in your gut ecosystem. Standard stool tests give a partial picture. GI-MAP gives you the full picture: pathogens, opportunistic organisms, beneficial bacteria, inflammation markers, immune function markers, and intestinal barrier integrity all in a single test.
The GI-MAP measures:
- Pathogenic bacteria — H. pylori (and its virulence factors), C. difficile, pathogenic E. coli, Salmonella, Shigella, Campylobacter, Vibrio, Yersinia, and more
- Opportunistic bacteria — overgrowth patterns of Klebsiella, Pseudomonas, Streptococcus, Staphylococcus, Methanobrevibacter (linked to methane-dominant SIBO), and others that drive inflammation when imbalanced
- Commensal / beneficial bacteria — Lactobacillus, Bifidobacterium, Akkermansia muciniphila, Faecalibacterium prausnitzii, and others key to gut health
- Parasites — Giardia, Cryptosporidium, Entamoeba histolytica, Blastocystis hominis, Dientamoeba fragilis, and intestinal worms (Ascaris, Taenia, and others)
- Fungi and yeasts — Candida species, Geotrichum, Rhodotorula, and Microsporidia
- Viruses — including cytomegalovirus and Epstein-Barr virus markers where relevant
- Intestinal health markers — Zonulin (leaky gut), Secretory IgA (gut immune function), Calprotectin (intestinal inflammation), Beta-glucuronidase (detox/hormone clearance), Elastase-1 (pancreatic enzyme function), and Steatocrit (fat malabsorption)
- Short Chain Fatty Acids (SCFAs): Acetate, Butyrate, Propionate, and six others measured to assess gut bacterial fermentation, gut barrier integrity, inflammation, and microbiome diversity. It can be added to your standard GI panel.
- Bile Acids: Comprehensive measurement of 25 bile acids in total concentrations, percentages, and ratios, evaluating bile acid metabolism, fat digestion, gut motility, and identifying root causes of IBS, IBD, and bile acid malabsorption. It can be added to your standard GI panel.
The test is processed by Diagnostic Solutions Laboratory in the US, the laboratory that developed the GI-MAP test. Results are interpreted by Dr. Menka Gupta* and translated into a personalised functional medicine plan addressing not just gut imbalances, but the protocols to heal your body

GI-MAP Test Procedure
The GI-MAP test is a simple, non-invasive at-home stool test, a single sample collection that is then sent to the Diagnostic Solutions Laboratory in the US for DNA-based analysis. The four-stage process below covers everything from preparation through to results.
How Long Does a GI-MAP Test Take?
01
Before the Test
Dietary preparation: Left to the discretion of your practitioner. For accurate digestion / fat malabsorption markers (Elastase-1, Steatocrit), some clinicians recommend consuming 70–100 grams of fat daily for three consecutive days before sample collection.
Medications and supplements: Do not start, stop, or change antibiotics, oral steroids, anti-inflammatory drugs, digestive enzymes, or biofilm disruptors without first consulting a doctor.
2 Weeks Prior: Stop taking spore-forming and soil-based probiotics; anti-parasitic, anti-fungal, and antibacterial agents (non-prescription); and NSAIDs (e.g., Advil, ibuprofen, naproxen).
2–3 Days Prior: Stop digestive support supplements (Betaine HCl, enzymes, gut-healing formulas, general probiotics); avoid aspirin for at least 2 days before collection.
Menstruation: Avoid collecting during menstruation. Keep a 3-day gap before or after your period to prevent false positives from blood traces.
Recent procedures: If you have had a colonoscopy in the last week, wait at least 7 days before sample collection. Recent gastrointestinal surgery may temporarily alter gut composition speak with Dr. Menka about timing.
Sample timing within the day: A first-morning sample is usually preferred but is not mandatory.
02
During the Test (Sample Collection)
The kit includes a collection container, collection paper, scoop, transport vial with preservative, and full instructions.
Collect a single stool sample using the provided materials, avoiding contact with urine or toilet water (the collection paper provided helps prevent this).
Use the scoop to transfer the required amount into the preservative-filled transport vial and seal tightly.
Label the vial and complete the requisition form included in the kit with your details and symptoms.
03
After the Test
The sample must be received by the lab within 10 days of collection.

How many follow up sessions do I need for a gut reset program?
Usually a gut reset program will usually need 3-4 follow up sessions to do the step by step gut healing program. The number of follow up sessions will depend on your stool result.
Can a GI Map detect leaky gut?
Yes. One key marker included in the test is zonulin, a protein linked to increased intestinal permeability commonly known as leaky gut. Elevated zonulin levels may indicate that the gut lining is compromised, allowing unwanted substances to pass into the bloodstream and trigger inflammation or immune responses.
How do I interpret my GI Map test results?
A functional medicine doctor can help interpret your GI-MAP results and create a personalized programme based on your report and symptoms.
Does the GI Map test for candida?
Yes, it checks for a few Candida species, Geotrichum, Rhodotorula spp. and some other fungus.
Do GI Maps show parasites?
Yes, it checks for protozoa (one cell parasite), like Blastocystis hominis, Dientamoeba fragilis, Entamoeba coli and more. It also looks for worms like Ascaris lumbricoides, Taenia to name a few.
What should I avoid before my GI Map test?
You should avoid the following before your GI-MAP test to ensure accurate results:
- Do not start, stop, or change certain medications such as antibiotics, oral steroids, anti-inflammatory drugs, enzymes, or biofilm disruptors without consulting your doctor, as they can affect gut bacteria.
- Do not ignore dietary preparation ensure you consume 70–100 grams of fat daily for three consecutive days before sample collection.
- Avoid collecting the sample during menstruation; keep a 3-day gap before or after your period to prevent false positives.
- Do not collect the sample immediately after a colonoscopy; wait at least one week.
- Avoid testing too soon after surgery without medical advice, as certain surgeries can alter gut composition.
- Always follow the instructions provided in your test kit or by your healthcare professional.
Are there any dietary restrictions before collecting a GI-MAP sample?
No specific dietary restrictions are required. Dietary preparation is left to the discretion of the healthcare provider, as they best understand what dietary factors may influence the patient’s microbiome based on clinical goals.
Can patients who recently had gastrointestinal surgery take the GI-MAP test?
Yes. Patients who have had recent GI surgery are still candidates for the GI-MAP. However, results may show temporarily elevated markers, such as calprotectin or the presence of blood, depending on healing status.
Is the GI-MAP suitable for patients with ostomies or surgically altered GI tracts?
Yes. Patients with ostomies or surgically altered gastrointestinal anatomy can take the GI-MAP. Results may vary depending on which section of the intestine was removed and the extent of the surgery.
