Abstract
The aim of the present study was to compare the gastric juice ammonia test to the CLO test for the diagnosis ofH. pylori infection in culture-proven cases by receiver operating characteristic (ROC) curve analysis. We studied 75 subjects (44 with chronic gastritis, 10 with gastric ulcer, 6 with duodenal ulcer, 8 with gastric cancer, and 7 normal) by endoscopy with biopsy for tissue diagnosis, culture ofH. pylori. CLO test, and by gastric juice ammonia determinations. The culture-positive group had significantly higher intragastric ammonia levels (13.7±5.8 mg/dl) than the negative group (4.9±2.4 mg/dl,PPH. pylori infection.Keywords
