Abstract

Background/Aims:
Pronto Dry test, a new rapid urease test, is consisted of a dry filter paper containing urea and has been reported to have a more rapid reaction time than others. We performed this study to compare the accuracy of Pronto Dry test with the other conventional tests for detection of H. pylori.
Methods:
One hundred patients underwent gastroscopy in our hospital for gastrointestinal symptoms. Biopsy specimens were taken for Pronto Dry test, polymerase chain reaction, culture, and histologic examination (Warthin-Starry stain). 13C-urea breath test was also performed. The results of Pronto Dry test were read after 1 hour.
Results:
The sensitivity, specificity, positive and negative predictive value of Pronto Dry test to diagnose H. pylori infection were 90.0%, 100%, 100%, and 90.9%, respectively. The kappa statistic between H. pylori status and Pronto Dry test was 0.90, demonstrating an acceptable level of reliability.
Conclusions:
Pronto Dry test has a high sensitivity and specificity, and can be used as a rapid test to diagnose H. pylori infection. (Korean J Gastrointest Endosc 2001;22:70 - 75)
