Cepheid, Sunnyvale, CA, received CE approval for a new infectious diseases assay on their GeneXpert system. The new assay enables rapid detection and differentiation of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG). The GeneXpert works with disposable, single-use cartridges that hold the sample and reagent in a small processing chamber. Many assays are already available like the MRSA, enteroviruses and Group B Streptococcus cartridges.
The GeneXpert itself is a closed, self-contained and automated platform. It combines on-board sample preparation with real-time PCR amplification and detection functions for nucleic acid analysis. The system is designed to purify, concentrate, detect, and identify targeted nucleic acid sequences and comes in a one, two, four, or 16-module configuration.
