Evaluation of the "one-minute" test for detecting Helicobacter (Campylobacter) pylori infection

The "one-minute" urease test to detect Helicobacter (Campylobacter) pylori infection was evaluated using histology and culture as the "gold standard". The test was performed in a blinded manner and compared with the conventional Christensen's urease test. Helicobacter pylori was detected in 88 of 100 consecutive patients attending the gastrointestinal clinic for upper endoscopy. Although the "one-minute" urease test was more sensitive [86% (76/88)] than the conventional Christensen's urease test [70% (62/88)], this difference was not statistically significant (P = 0.22). Histology was the most sensitive [97% (85/88)] whilst culture was 80% (70/88) sensitive. All tests exhibited specifications of 100%. The "one-minute" urease test is a simple, rapid and highly specific test to detect Helicobacter pylori which can be performed at endoscopy.
