Rapid urease test provides specific identification of Campylobacter pylori in antral mucosal biopsies.
In a prospective study, three antral biopsies were taken from 175 dyspeptic patients during routine endoscopy. One biopsy was inserted immediately into a gel-containing well of a CLOtest slide and two biopsies were sent to histopathology. Using the CLOtest, 84 of the 175 samples (48%) detected urease activity in the gastric biopsy, suggesting infection with Campylobacter pylori. Histopathologic...
متن کاملEvaluation of the one-minute ultra-rapid urease test for diagnosing Helicobacter pylori.
To determine the diagnostic accuracy of the one-minute ultra-rapid urease test for diagnosing Helicobacter pylori infection, two biopsies were taken from both the gastric corpus and antrum from 1000 patients undergoing upper gastrointestinal endoscopy. All the biopsies were subjected to the one-minute ultra-rapid urease test before imprint smears were prepared from them. Thereafter, the biopsie...
متن کاملEvaluation of a rapid urease test to detect Campylobacter pylori infection.
Seventy-five consecutive patients referred for upper gastrointestinal tract endoscopy were evaluated for Campylobacter pylori infection by pathology, culture, and a biochemical test to detect bacterial urease. Forty-eight patients (64%) had C. pylori present based on pathology or culture or both. Thirty-two urease tests were positive after 1 h, all in patients with C. pylori detected by the two...
متن کاملOptimization of a medium for the rapid urease test for detection of Campylobacter pylori in gastric antral biopsies.
We developed a buffered azide-free urea medium which is sensitive, specific, and nontoxic for rapid detection of Campylobacter pylori in gastric biopsies. Detection of urease produced by the organism provides the basis for the test. The substrate is urea in monobasic sodium phosphate buffer, and phenol red provides indication of the pH change that results from urease activity. A rapid change fr...
