Introduction

Overview

Overview

Testing of H.pylori infection is very important for treating ulcers. H.pylori is tested by 2 methods, invasive and non-invasive. Rapid urease testing is invasive test which is used as diagnostic study of choice. Stool monoclonal antigen test is one of the non-invasive test which is used to diagnose active infection.

Other diagnostic studies

Other diagnostic studies

Testing of H.pylori infection is very important for treating ulcers.H.pylori is tested by 2 methods : invasive and non-invasive tests.[1][2]

Invasive tests

Diagnostic testing for H. pylori infection
Endoscopic testing Prerequisites
Rapid urease testing Patients who have not been on a PPI within 1-2 weeks or an antibiotic or bismuth within 4 weeks of endoscopy
Histology Patients who have been taking a PPI, antibiotics, or bismuth, endoscopic testing should include biopsies from the gastric body and antrum
Culture and Polymerase Chain Reaction Not routinely recommended

Noninvasive tests

  • Urea breath test (carbon 13) tests:Urea breath test used to document eradication therapy and should be performed four to six weeks after completion of eradication therapy
    • Proton pump inhibitors (PPIs) should be stopped for two weeks before the test
    • Requires the ingestion of urea labeled with the nonradioactive isotope Carbon 13 or Carbon 14
  • Stool monoclonal antigen tests:
    • Detects active infection and is used as a test of cure
    • PPIs should be stopped for two weeks before testing
    • Test is done by following methods:[9][10][11][12][13]
      • Enzyme immunoassay
      • Immunochromatography
      • Antibody tests
Non-invasive testing Comments
Urea breath tests Provide reliable means of identifying active H. pylori infection before antibiotic treatment and is the most reliable nonendoscopic test to document eradication of infection
Serological testing Limited use in low prevalence H. pylori populations
Stool monoclonal antigen Enzyme immunoassay Used to detect active infection and can be used to document eradication of infection
Immunochromatography
Antibody tests
