    Abstract

    Molecular diagnostics for influenza and respiratory syncytial virus (RSV) have become commonplace and a variety of tests and systems have been FDA-cleared for use in the United States. We performed a retrospective study to compare the Cepheid Xpress Flu/RSV assay to the Xpert Flu/RSV XC assay, using laboratory-developed tests (LDTs) as the reference method. The Xpress assay was 100% accurate as compared to the LDTs, while the Xpert Flu/RSV XC was 96.0% accurate. The Xpress test was determined to be faster and more sensitive than the XC.
