EVALUATION OF THE COPAN FLOCKED ESwab™ VS COPAN DUAL SWABS FOR ANTERIOR NARES SPECIMEN COLLECTION FOR MRSA/ORSA USING THE XPERT MRSA ASSAY

Introduction

The Xpert MRSATM Assay has been FDA-approved for testing on the GeneXpert Dx System using dual swabs made exclusively for Cepheid (Copan Diagnostics, Inc.) for collection and transport of anterior nares specimens in liquid Stuart’s medium (139CFA). ESwabs (Copan Diagnostics, Inc.) use a nylon flocked single swab liquid-based collection and transport system with a uniquely designed nylon flocked single swab. When the swab is placed in transport medium (modified liquid Amies), organisms are completely and immediately eluted. Baptist Health developed a robust MRSA/ORSA surveillance program including all patients entering the ICUs at all five hospitals in the healthcare system. Using a laboratory and nursing interdepartmental approach, a randomized IRC-approved study was designed to compare the Xpert MRSA results obtained with our current dual premoistened swabs with pre-moistened flocked ESwabs.
