Comparison of ESwab and Wound Fiber Swab Specimen Collection Devices for Use with Xpert SA Nasal Complete Assay

Paired nasal swab specimens were collected from patients who were undergoing routine methicillin-resistant Staphylococ-cusaureus (MRSA) screening prior to elective cardiac or orthopedic procedures. Each patient was swabbed using a traditional wound fiber liquid Stuart swab and an ESwab device, a flocked swab with a modified liquid Amies microbiology transport medium. The two specimens were tested using the Cepheid Xpert SA Nasal Complete assay. Results demonstrated a 95.5% agreement between the ESwab and the FDA-cleared wound fiber swab collection device.
