Accuracy of Four Commercially Available Serologic Tests, Including Two Office‐based Tests and a Commercially Available ¹³C Urea Breath Test, for Diagnosis of <i>Helicobacter pylori</i>

Abstract

The Meretek 13C urea breath test is an excellent test, but is considerably more expensive than serologic tests. The FlexSure HP and the QuickVue One-Step office-based qualitative IgG serologic antibody tests gave similar results to laboratory based quantitative antibody tests, and are acceptable for initial diagnosis of H. pylori infection. The advantages of the office-based tests are low cost, simplicity, and immediacy of results.
