  Purpose: To develop a multiplex-urease PCR assay specific for ureA and ureB genes directly from gastric biopsy specimens and compare the results of multiplex-urease PCR assay with rapid urease test (RUT) and histopathology. Methodology: This study was conducted on 109 patients. A RUT was run; histopathological staining and multiplex urease PCR were applied to biopsy specimen to detect H. pylori. Multiplex-urease PCR, RUT and histopathology results were compared by calculating Cohen’s kappa coefficient. Results: A multiplex-urease PCR assay specific for ureA and ureB genes was developed to detect H. pylori directly from biopsy specimens. Cohen's kappa coefficient results of histopathological staining and multiplex-urease PCR indicate a substantial agreement. There was a moderate agreement between the resul.. View More»
