We evaluated the RapID Yeast Plus System using 117 fresh and frozen clinical yeast isolates. The Uni-Yeast-Tek System was used to establish the correct identification. The Vitek System was used as the arbiter for any discrepant results, along with morphology. Of 117 isolates tested, the RapID Yeast Plus System identified 96.6% correctly. The RapID Yeast Plus System is an accurate and reliable alternative to other commonly used yeast identification systems.
