Comparison of commercial molecular assays for toxigenic Clostridium difficile detection in stools: BD GeneOhm Cdiff, XPert C. difficile and illumigene C. difficile

Three commercial molecular assays were evaluated for toxigenic Clostridium difficile detection in stools. As compared to toxigenic culture, BD GeneOhm Cdiff (BD Diagnostics), XPert C. difficile (Cepheid) and illumigene C. difficile (Meridian Bioscience) demonstrated respectively a sensitivity of 95.5%. 97.8% and 86.7% and a specificity of 97.9%. 97.9% and 100%.
