Cepheid Xpert Carba-R Update

Cepheid has announced the international availability of an update to Xpert Carba-R, with the addition of two newly emerging carbapenemase genes, OXA-181 and OXA-232. The molecular test also detects and differentiates among the five most prevalent mechanisms of carbapenem resistance, namely KPC, NDM, VIM, IMP-1, and OXA-48. The Xpert Carba-R cartridge now detects 91 resistance genes distributed among five distinct gene families, many of which are extremely difficult to detect by using conventional laboratory procedures, in less than an hour, Cepheid noted.
