Diagnostic Performance of Six Tests for Helicobacter pylori Infection in Peptic Ulcer Bleeding: A Prospective Head-to-Head Comparison
Background: Rapid urease test (RUT) is widely used for diagnosing Helicobacter pylori (HP) because it is inexpensive and practical. However, its accuracy is reduced in peptic ulcer bleeding (PUB). We prospectively performed a head-to-head comparison of diagnostic tests in the same patients to evaluate their performance in this setting. Methods: After endoscopic hemostasis, gastric biopsies were obtained for RUT, histology, and PCR. Blood samples were collected for current infection marker (CIM) and anti-urease anti …
