Test Code RSPCR2 Influenza A/B, RSV, and SARS-CoV-2, PCR

Important Note

False negative results may occur if virus is present at low levels below the analytical limit of detection. Negative results do not preclude SARS-CoV-2, influenza, or RSV infection and should not be used as the sole basis for treatment or other patient management decisions. Results from this assay should be correlated witht the clinical history.

Infectious

Additional Codes

EPIC LAB4608

Purpose

The Xpert Xpress CoV-2/Flu/RSV plus test is intended for use in the simultaneous in vitro qualitative detection and differentiation of severe acute respiratory syndrome coronavirus (SARS-CoV-2), influenza A, influenza B, and respiratory syncytial virus (RSV) viral RNA in nasopharyngeal swab specimens collected from individuals with signs and symptoms of respiratory tract infection. Clinical signs and symptoms of respiratory tract infection due to SARS-CoV-2, influenza A/B, and RSV can be similar.
