Detect Active Helicobacter pylori Infection
The H. pylori Stool Antigen Test (EIA) is a non-invasive diagnostic test used to detect active infection with Helicobacter pylori, a bacterium that commonly infects the stomach lining and is associated with gastritis, acid reflux, stomach ulcers, and digestive discomfort.
This test works by identifying H. pylori antigens (proteins released by the bacteria) in a stool sample using a highly sensitive enzyme immunoassay (EIA) method. Because it detects bacterial components directly, the test helps identify current infection rather than past exposure.
Why is this test important
H. pylori infection is one of the most common causes of chronic digestive symptoms, including:
- Persistent acidity or reflux
- Bloating and indigestion
- Nausea or stomach discomfort
- Peptic ulcers
- Unexplained iron or vitamin B12 deficiency
Early detection allows for targeted treatment and better digestive health outcomes.
Test Highlights
✔ Detects active H. pylori infection
✔ Non-invasive stool test
✔ Highly accurate (high sensitivity and specificity)
✔ Can also be used to confirm eradication after treatment
Sample Required
Stool sample
Detailed instructions will be provided after booking the test.
Preparation Guidelines
For the most accurate results, avoid the following before testing:
-
Proton pump inhibitors (PPIs) for at least 2 weeks
-
Antibiotics for at least 4 weeks
-
Bismuth-containing medications for 2 weeks
These medications may suppress the bacteria and affect test accuracy.
Who should consider this test?
This test may be recommended if you experience:
- Chronic acidity or reflux
- Gastric discomfort or bloating
- Recurrent gastritis or ulcers
- Persistent digestive symptoms with unclear cause
- Suspected H. pylori infection
- Follow-up testing after H. pylori treatment
Turnaround Time
Typically, 3-days after sample submission.
