Real-Time PCR Improves Helicobacter pylori Detection in Patients with Peptic Ulcer Bleeding

Abstract

Real-time PCR improves the detection of H. pylori infection in histology-negative formalin-fixed paraffin-embedded biopsy samples obtained during PUB episodes. The low reported prevalence of H. pylori in PUB may be due to the failure of conventional tests to detect infection.
