Ulcer & H. pylori Test
Helicobacter pylori causes over 90% of duodenal ulcers and 70–80% of gastric ulcers. A simple blood or stool test identifies the infection, so treatment can eliminate the root cause, not just the symptoms.
Two Ways to Detect H. pylori
H. pylori is a spiral-shaped bacterium that colonises the stomach lining. Left untreated it causes ulcers, chronic gastritis, and, rarely, stomach cancer. Accurate testing is the first step to cure.
Blood Antibody Test (IgG)
A serum IgG antibody test detects past or present H. pylori infection. It is the simplest method, a standard venous blood draw, same-day results, no special preparation. Limitation: antibodies persist for months after successful treatment, so it cannot confirm eradication; use stool antigen for test-of-cure.
- No fasting required
- Best for initial diagnosis
- Sensitive: ~95% detection rate
- Not suitable for post-treatment follow-up
Stool Antigen Test (HpSA)
The stool H. pylori antigen (HpSA) test detects active proteins shed by live bacteria in the gut. It is the gold-standard non-invasive test, more accurate than blood IgG for active infection, and the preferred method to confirm eradication 4 weeks after completing antibiotic therapy.
- Confirms active infection (not just past exposure)
- Preferred test-of-cure method
- Stop PPIs and antibiotics 2 weeks before
- Small stool sample collected at home
What H. pylori Does
H. pylori disrupts the stomach's protective mucus layer, allowing acid to damage the underlying tissue. Chronic colonisation leads to peptic ulcers, duodenitis, and MALT lymphoma. Eradication with a 14-day triple-therapy antibiotic regimen cures the majority of cases permanently.
- Peptic ulcer disease (gastric & duodenal)
- Chronic antral gastritis
- Non-ulcer dyspepsia (functional)
- Rarely: gastric cancer, MALT lymphoma

Simple Steps for Accurate Results
Blood Test (IgG)
No fasting or special preparation required. Come in at any time of day. A small venous blood sample is taken, and results are ready the same day. No need to stop medications for the blood IgG test.
Stool Antigen Test
Stop proton pump inhibitors (omeprazole, lansoprazole, pantoprazole) for 2 weeks before the test, and antibiotics for 4 weeks before. Collect a small stool sample in the container we provide, no dietary restriction needed. Bring the sample to the lab within 4 hours or keep refrigerated (not frozen).
After Your Result
A positive result does not require immediate alarm: H. pylori is eminently treatable. Standard triple therapy (two antibiotics + a PPI for 10–14 days) achieves eradication in ~85–90% of cases. We will guide you on next steps and when to return for a test-of-cure.
More Than a Positive or Negative
We offer both blood IgG antibody and stool HpSA antigen tests. We help you choose the right method based on whether you're diagnosing or confirming eradication.
Results include interpretation and next-step guidance: not just reactive/non-reactive. You'll understand what a positive result means for your management before you leave.
Our team advises on standard eradication regimens and when to schedule your follow-up stool antigen test, ensuring you don't just treat, but confirm cure.
