Test Overview

Test Methodology

Cepheid GeneXpert Xpress- RT PCR

Test Usage

The Cepheid Xpert Xpress SARS-CoV-2/Flu/RSV assay is a rapid, real-time RT-PCR test intended for the simultaneous qualitative detection and differentiation of SARS-CoV-2, influenza A, influenza B, and respiratory syncytial virus (RSV) viral DNA in either nasopharyngeal swab, nasal swab or nasal wash/aspirate specimens collected from individuals suspected of respiratory viral infection consistent with COVID-19 by their healthcare provider. The Cepheid Xpert Xpress SARS-CoV-2/Flu/RSV assay is only for use under the Food and Drug Administration’s Emergency Use Authorization.

Reference Range

Not Detected for influenza A, influenza B, respiratory syncytial virus, and SARS-CoV-2

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Specimen Requirements

Collection Offsite

Gently insert mini-tipped flocked nasopharyngeal swab (swab on flexible plastic shaft) through the nostril and into the nasopharynx, reaching the posterior nasopharynx. Gently rotate swab, then remove, and break swab off into tube of transport media. Make sure the swab is fully immersed in the transport media, and that the shaft is short enough to completely tighten the cap. For best results testing should be performed immediately after collection. Obtaining columnar epithelial cells will enhance reliability of viral detection.
