Optimal Site for Rapid Urease Test in the Stomach

April 16, 2018 updated by: Jun-Hyung Cho, Soonchunhyang University Hospital

Comparison of Rapid Urease Test Between the Gastric Body and Antrum in Helicobacter Pylori-Infected Stomach

The accurate diagnosis of H. pylori infection is an important step for establishing the strategy for gastric cancer prevention. During endoscopy, rapid urease test (RUT) is the first of biopsy-based H. pylori tests. Despite indirect test for H. pylori detection, RUT shows rapid result with good sensitivity and specificity. Several study reported that H. pylori density was related to positive reaction time of RUT. However, there was no study comparing the positive reaction times of RUT according to biopsy site, degree of gastric atrophy, and intestinal metaplasia.

Detailed Description

The aims of this study were to: (1) assess the positive reaction times of RUT in the body and antrum, (2) investigate the association between the difference of RUT results (body and antrum) and gastric atrophy, and intestinal metaplasia, and (3) evaluate the optimal biopsy site for RUT according to degree of gastric atrophy in Korean population.
