Abstract : The aim of this study was to evaluate the accuracy of five diagnostic tests
for H. pylori. Each gastric specimen underwent PCR, culture and histological examinations. Serology and +-C῎UBT analyses were also performed before or after endoscopy. The sensitivity and specificity were as follows ; for PCR : 3240 and +**,
for culture : 3*4- and +**, for the histological examination : 204+ and +**, for
+C῎UBT : 3-4+ and 3/42, and for serology : 3240 and 114+. These results suggest that a combination of the above diagnostic tests would likely improve the
accuracy of detecting H. pylori infection.
Key words : Helicobacter pylori, diagnostic test, PCR,
