Do you struggle with symptoms like persistent bloating, irregular digestion, fatigue, or unexplained skin issues? These could be signs of an imbalanced gut microbiome—also known as gut dysbiosis. Unlike one-off infections or food-related triggers, microbiome imbalances tend to be chronic and systemic, affecting everything from immunity to mental clarity.

At Regis Medical, we offer comprehensive stool-based gut microbiome testing to uncover potential microbial imbalances and guide personalised interventions. While we don’t position this test as a first-line investigation for common issues like IBS, eczema, or fatigue, it can offer deeper insight—particularly for patients who have explored conventional diagnoses and are seeking further clarity on their health.

We believe in using microbiome testing as part of a holistic and medically guided journey. Our doctors work with you to interpret results and tailor follow-up care, whether that means dietary shifts, probiotic support, or additional testing where appropriate.

Did You Know?

  • Over 70% of your immune cells reside in your gut.
  • Your gut produces 90% of the body’s serotonin — a key mood regulator.
  • Dysbiosis (imbalanced microbiome) has been linked to IBS, eczema, fatigue, obesity, and anxiety.
  • Even if you eat well, poor microbiome diversity can block nutrient absorption and trigger inflammation.

What Is a Gut Microbiome Test?

The Gut Microbiome Test is a stool-based diagnostic test that analyses the community of bacteria, fungi, and other microorganisms living in your digestive tract. These microbes affect more than just digestion—they influence immunity, mental health, inflammation, metabolism, and even skin and hormonal balance.

Why Does Gut Health Matter?

Your gut is often called the “second brain” for a reason. A healthy gut microbiome helps to:

  • Break down food and absorb nutrients
  • Regulate immune responses and reduce inflammation
  • Maintain a strong gut barrier (preventing leaky gut)
  • Support hormone balance
  • Influence mood and brain health through the gut-brain axis

An imbalanced gut microbiome—known as dysbiosis—can contribute to a wide range of chronic symptoms and health issues.

Who Should Consider a Gut Microbiome Test?

This test is ideal for individuals who experience:

  • Bloating, gas, or irregular bowel movements
  • Chronic constipation or diarrhea (including IBS)
  • Skin issues (e.g. acne, eczema, rosacea)
  • Food intolerances or unexplained sensitivities
  • Persistent fatigue or “brain fog”
  • Recurring yeast or fungal infections
  • Autoimmune conditions or low immunity
  • History of long-term antibiotic use
  • Weight fluctuations or difficulty losing weight

Even if you're symptom-free, a gut microbiome test can be useful for optimising wellness and preventive health.

What the Test Measures

Your stool sample will be analysed for:

  • Bacterial diversity and abundance (good vs bad bacteria)
  • Pathogenic bacteria, fungi, or parasites
  • Digestive efficiency (e.g. fibre fermentation, butyrate levels)
  • Inflammation markers (e.g. calprotectin)
  • Gut permeability risk
  • Microbiome balance and probiotic recommendations

Depending on your results, we may recommend further steps like food sensitivity testing, supplementation, or TCM/functional medicine referrals.

How Does the Test Work?

  • Collection: Stool sample collected at home using an easy-to-use kit
  • Fasting: Not required
  • Time required: 10–15 minutes (collection), test kit provided by clinic
  • Turnaround: Results ready in 2–3 weeks

General Enquiry

What is the gut microbiome?

Your gut microbiome is the collection of trillions of bacteria, viruses, and fungi living in your digestive tract. A healthy balance supports digestion, immune function, metabolism, and even mood.

What is a gut microbiome test?

It’s a stool test that analyses the types and amounts of bacteria in your gut. Advanced lab methods (like DNA sequencing) identify your gut flora, measure diversity, and look for imbalances (dysbiosis).

Who should consider doing this test?

You might benefit from gut microbiome testing if you have:

  • Chronic bloating, gas, or irregular stools (IBS-like symptoms)
  • Unexplained fatigue or brain fog
  • Suspected food sensitivities
  • Skin issues like eczema or acne
  • Frequent infections or low immunity

Some people also use it proactively for general wellness.

How is the test done?

It’s simple and non-invasive:

  • You collect a small stool sample at home using a kit provided by our clinic.
  • Return it to us.
  • The lab analyses your sample and generates a detailed report.
Do I need to stop my medications or probiotics?
You may be required to stop taking probiotics a few days before the test. As for chronic medications, please consult our Doctors.
Do I need to fast before collecting the sample?
No fasting is required. Just follow the kit instructions carefully.
What does the test report show?

It includes:

  • Relative levels of different bacteria species (good vs potentially harmful strains)
  • Microbial diversity scores (linked to resilience and gut health)
  • Markers of gut inflammation, digestion efficiency, or leaky gut risk
Can this test diagnose diseases?
No. It doesn’t diagnose diseases like colon cancer or IBS. It provides insights into gut balance that may help explain symptoms and guide dietary or lifestyle adjustments.
