Clinically Validated Gut Microbiome Test for Digestive Health in Singapore
Imagine your gut as a lush, microscopic rainforest. This “rainforest” is home to trillions of organisms, including bacteria, fungi, and viruses. Collectively, they make up your gut microbiome. These tiny microorganisms play a vital role in overall digestion, metabolism, immunity, and mood regulation as well.
However, when these microbes become imbalanced, it can lead to various symptoms in the body, such as bloating, irregular bowel movements, inflammation, food sensitivities, and many more.
A Gut Microbiome Test takes the guesswork out by analysing exactly what’s living inside your gut the good, the bad, and the missing. The result is a clear, personalised picture of your gut health, metabolism, immune function, and gut-brain balance, interpreted by Dr. Menka Gupta and turned into a focused plan to help you actually feel better.
Find out what’s really going on inside your gut.
A complete, DNA-level read of your gut microbiome interpreted by Dr. Menka Gupta and translated into a personalised plan to fix what’s actually driving your symptoms.

What is the Gut Microbiome?
Each person’s microbiome is as unique as a fingerprint, shaped by their environment, what they eat, and even how they were born. When you decide to test your gut microbiome, you are essentially taking a census of this internal city to see if the “good neighbors” are thriving or if the “bad guys” are starting to take over.
What is a Gut Microbiome Test?
A gut microbiome test is a simple way to map out exactly who is living in your digestive system. Unlike the basic stool tests, you might get a comprehensive microbiome test kit that uses advanced DNA sequencing.
By looking at the genetic material of the microbes in a small stool sample, the lab can identify thousands of different species. It shows you the balance of your bacteria, identifies potential overgrowths of yeast or “bad” bacteria, and measures how well you are digesting your food. Essentially, an at-home gut health test turns your biological data into a personalised roadmap for your wellness journey.
What Does the Gut Microbiome Do?
Your gut microbiome is far more than just a digestive helper; it's a full-time metabolic factory that runs 24/7. Its most obvious job is breaking down the foods your body can't handle, like fibre. Without a healthy gut microbiome, you might find that your body struggles to absorb the very nutrients you're eating.
Additionally, beyond digestion, the gut plays an important role in managing the immune system as well. Also, it regulates the serotonin production in the gut and influences neurotransmitters such as GABA and dopamine, responsible for mood balance and stress response. That's why a gut health test is recommended for individuals struggling with irritability, mood disorders, or brain fog.
Various Types of Gut Microbiome Tests
Not all gut microbiome tests are the same. At NutraNourish, we work with several clinically validated tests and choose the one most suited to your symptoms and goals:
GI-MAP (+OMX)
Frequently used for patients with chronic gastrointestinal dysfunction. This assay uses quantitative Polymerase Chain Reaction (qPCR) technology and is designed to detect low-abundance pathogens or parasites that conventional testing may miss.
GI Effects (Genova)
A comprehensive diagnostic that integrates genomic sequencing with functional biomarkers, providing critical data on metabolic markers including the efficiency of lipid, carbohydrate, and protein digestion.
GI360
Uses a multi-modal diagnostic approach, employing three distinct methodologies to ensure a high-fidelity mapping of the gastrointestinal environment.
CDSA
A traditional yet reliable culture-based methodology. It involves laboratory cultivation of bacteria to determine the sensitivity and effectiveness of specific antimicrobial agents or natural interventions against pathogenic strains.
Gut Zoomer
An advanced stool test offering a more detailed analysis than traditional stool testing. It analyses bacteria, fungi, viruses, and protozoa, alongside biomarkers related to allergic inflammation, gut-driven immune activity, digestion, gut barrier function, and microbial metabolites.
During your consultation, Dr. Menka Gupta* recommends the most appropriate test based on your symptoms, medical history, and health goals.
Who Should Take a Gut Microbiome Test?
You don’t need to wait until you’re in pain to test your gut microbiome, it’s useful even before symptoms become serious. It’s a must-have for people dealing with constant bloating, gas, diarrhoea, or constipation. Stubborn skin issues like acne or eczema can often be traced back to an unhealthy gut. Chronic fatigue and brain fog are strong indicators that your gut bacteria may be out of balance. Even if you feel fine, a gut health home test can help you reach peak performance. It gives you a personalised approach to improve digestion, metabolism, immunity, and overall wellness.

Which Health Issues Does Gut Microbiome Test Help?
Gut microbiome imbalance is increasingly recognised as a root cause behind a wide range of conditions. The Gut Microbiome Test can help identify gut-related drivers of:
Why Is Gut Microbiome Testing Important?
See exactly what's living in your gut
DNA-level sequencing identifies thousands of bacterial, fungal, and viral species far beyond what a standard stool test can detect so you know precisely what's out of balance.
Stop guessing with probiotics and diets
Generic probiotics and trending diets work for some people and not others because gut microbiomes are individual. Testing tells you exactly what your gut needs, so your protocol actually moves the needle.
Fix the root cause, not just symptoms
Many chronic issues skin, mood, fatigue, immunity trace back to gut imbalance. Testing connects the dots so you address the cause, not just the symptom.
Personalised, data-backed plan
Your results feed directly into a customised nutrition, supplement, and lifestyle plan from Dr. Menka Gupta built around your specific microbiome, not a one-size-fits-all protocol.
Catch issues early
Gut imbalances often start years before symptoms show. Early detection means you can course-correct before they progress to chronic conditions like IBS, autoimmunity, or metabolic disorders.
Convenient, private, at-home
No clinic visit. The kit arrives discreetly, sample collection takes a few minutes, and results are delivered online.

How Is a Gut Microbiome Test Performed?
The idea of a stool test makes some people nervous, but the gut health test kit is designed to be very easy and private. Once you order your biome test kit, it arrives at your door in a discreet package. Inside, you'll find a collection container and a small vial with preservative liquid. You collect a tiny sample of stool (about the size of a grape) using the provided scoop, place it in the vial, shake to mix it with the preservative, and seal it tightly. The liquid keeps the DNA stable so it doesn't change during the mail process. You then pop it into the prepaid shipping envelope and send it back to the lab. A few weeks later, you get your results online. It's that simple.
What Will A Gut Microbiome Test Tell Me?
Depending on the test selected, your Gut Microbiome Test report can tell you:
Together, these markers reveal not just what's out of balance, but why — and that's the foundation Dr. Menka Gupta* uses to build your personalised gut healing plan.

What Our Customers Say
Frequently Asked Questions (FAQ)
Is it worth getting a gut microbiome test?
Definitely. Most people spend hundreds of dollars on generic supplements they don’t actually need. The best gut microbiome test gives you a clear “yes” or “no” on what your body is lacking. It’s an investment in your long-term health that helps you avoid trial-and-error with your diet and expensive probiotics.
How is a gut microbiome test different from a routine doctor’s stool test?
A routine doctor’s test is reactive; it looks for a specific infection, disease, or dangerous parasite. A gut health test is proactive. It looks at the whole ecosystem, measuring the good bacteria and functional markers, helping you understand gut balance, digestion, immunity, and overall wellness even before issues arise.
Who should consider getting a gut microbiome test?
Anyone with IBS, autoimmune issues, mental health concerns, or chronic skin problems should definitely consider it. It’s also great for people who feel “stuck” with their weight, energy levels, or who simply want to peak their performance and prevent disease before it starts.
Do I need to fast or change my diet before the test?
No fasting is required. In fact, most experts want you to eat your normal diet before using your gut testing kit. This ensures the results show what your gut looks like on a typical day. Avoid taking probiotics or antibiotics for a few weeks before testing.
Will my report tell me exactly what foods to eat or avoid?
Some advanced stool tests do offer food guidance to support gut health. However, it’s always best to work with a functional medicine expert who can first interpret your test results and then create a personalised gut healing program built specifically for you.
Can a microbiome test replace medical tests ordered by my doctor?
No. A gut microbiome test is a functional wellness tool that provides insights into your digestive health, microbiome balance, and overall gut function. It cannot replace medical diagnostics such as colonoscopy, blood tests, or other clinical investigations.
