RIDA ®GENE Helicobacter pylori PCR on the ELITe InGenius System

AbstractPCR detection ofHelicobacter pylori infection in gastric biopsies allows the detection of this bacterium and the mutations associated with macrolide resistance. The aim of this study was to evaluate the performance of RIDA ®GENEH. pylori PCR (r-Biopharm) on the ELITe InGenius System (Elitech). Two hundred gastric biopsies were obtained. These biopsies were ground in nutrient broth. Two hundred microliters of this suspension was treated with proteinase K, and then, 200 µL was transferred to an ELITe InGenius sample tube and tested using RIDA®GENEH. pylori PCR reagents. In-houseH. pylori PCR was used as a reference. The sensitivity of RIDA ®GENEH. pylori PCR with ELITe InGenius was 100%, the specificity was 98% (95% confidence interval (CI), 95.3 –100%), the PPV was 98% (95% CI, 95.3–100%), and the NPV was 100% for the detection ofH. pylori. All of these parameters were 100% for the categorization of macrolide resistance. The adaptation of RIDA ®GENEH. pylori PCR reagents on the ELITe InGenius System was successful. This PCR is easy to use on this system.
