Comparative StudyComparison of biopsy and serological methods of diagnosis of Helicobacter pylori infection and the potential role of antibiotics.
Endoscopic biopsy and serological methods were compared for their ability to detect Helicobacter pylori infection in patients undergoing upper gastrointestinal endoscopy at a state university hospital. ⋯ Serological evidence of H. pylori infection was consistently greater than the prevalence of infection documented by biopsy methods in this study, suggesting suppression or recent clearance of infection. Further studies are needed to examine the factors that may affect the detection of H. pylori infection.
