Quick Answer

A stool test looks at what is actually happening in the gut: bacterial balance, how well food is digested, and whether infection is present.

A stool test looks at what is actually happening inside your gut: bacterial balance, how well your gut digests food, signs of inflammation, and whether an infection such as H. pylori is present. It is one of the most direct tests available, because it examines the end result of digestion rather than inferring it from blood.

What we measure

The base panel looks at occult blood, faecal fat which indicates malabsorption, calprotectin as a marker of gut inflammation, pancreatic elastase for digestive enzymes, and H. pylori antigen. An extended panel adds a microbiome profile and antibiotic sensitivity once tests confirm an infection.

When you need a stool test

  • Bloating that persists for more than a few weeks
  • Diarrhoea and constipation alternating
  • Upper abdominal pain, early fullness, or nausea after eating
  • Weight loss with no clear cause
  • Iron or B12 deficiency that returns although you take supplements

How this test runs

  1. 01Stop certain medication before testingProton pump inhibitors stop two weeks before H. pylori testing, because they suppress the bacteria temporarily and produce false negatives. Antibiotics stop four weeks before. Do not stop any medication without speaking to a doctor first.
  2. 02Avoid bismuth and high-dose probioticsFor a week beforehand.
  3. 03Results are read alongside symptomsA positive H. pylori result leads to a treatment regimen based on current guidance, followed by confirmation testing six weeks after treatment ends. Microbiome results are not read as simply good or bad.

Interpretation

How we use the results

A positive H. pylori result leads to a treatment regimen based on current guidance, followed by confirmation testing six weeks after treatment ends. Microbiome results, meanwhile, are not read as simply good or bad. We read them alongside symptoms and diet. See the gut health pathway, or the food allergy test if symptoms track particular foods.

What it cannot do

What a stool test cannot tell you

It does not look at structure, so it cannot detect ulcers, polyps, or changes in the gut lining. If warning signs appear, such as vomiting blood, black stools, difficulty swallowing, or sudden weight loss, endoscopy is still needed and we will refer you to a gastroenterologist. Treatment guidance follows the Ministry of Health Malaysia. Book a consultation.
To map gut bacterial composition rather than look for an infectious organism, read the gut microbiome test.

H. pylori and why it matters in Malaysia

H. pylori is a bacterium that infects the stomach lining and links to ulcers and to long-term stomach cancer risk. Infection rates in Malaysia vary between population groups, although it is common enough to screen for whenever upper abdominal symptoms persist. The stool antigen test is non-invasive and needs no endoscopy.
