[Rapid urease test].
The rapid urease test is a simple, sensitive, and highly specific test that enables the endoscopist to diagnose Helicobacter pylori infection in the endoscopy room. Determination of the infection status of Helicobacter pylori by biopsies from the gastric body had a significantly higher sensitivity than antral biopsies. A false-negative reaction by rapid urease test occurred the use of antibiotics (correlates with clearance of the bacteria) and the use of proton pump inhibitor or a part of mucosal protective agents(correlates urease inhibitory effect) and in the case of non-urease producing Helicobacter pylori. The rapid urease test satisfactory overall sensitivity before eradication treatment. However, the sensitivity of these rapid urease tests was lower after eradication than before eradication.
