Clinical signs and symptoms of respiratory viral infection due to SARS-CoV-2, influenza and RSV can be similar. Testing is limited to laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), 42 U.S.C. §263a, that meet requirements to perform high, moderate or waived complexity tests. The cobas® liat SARS-CoV-2, Influenza A/B & RSV nucleic acid test is authorized for use at the Point of Care (POC), i.e., in patient care settings operating under a CLIA Certificate of Waiver, Certificate of Compliance, or Certificate of Accreditation. Results are for the simultaneous detection and differentiation of SARS-CoV-2, influenza A, influenza B and RSV viral RNA in clinical specimens and are not intended to detect influenza C virus. SARS-CoV-2, influenza A, influenza B and RSV RNA are generally detectable in nasal swab and nasopharyngeal swab specimens during the acute phase of infection. Positive results are indicative of the presence of SARS-CoV-2, influenza A, influenza B and/or RSV RNA; clinical correlation with patient history and other diagnostic information is necessary to determine patient infection status. Positive results do not rule out bacterial infection or co-infection with other pathogens not detected by the test. The agent detected may not be the definitive cause of disease. Negative results do not preclude SARS-CoV-2, influenza A, influenza B and/or RSV infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations, patient history, and/or epidemiological information. The cobas® liat SARS-CoV-2, Influenza A/B & RSV nucleic acid test is intended for use by trained operators specifically instructed in the use of the cobas® liat system and the cobas® liat SARS-CoV-2, Influenza A/B & RSV nucleic acid test. The cobas® liat SARS-CoV-2, Influenza A/B & RSV nucleic acid test is only for use under the Food and Drug Administration’s Emergency Use Authorization.   en Test principle The test is performed on the cobas® liat analyzer which automates and integrates sample purification, nucleic acid amplification, and detection of the target sequence in biological samples using real-time RT-PCR assays. The assay targets both the ORF1 a/b non-structural region and membrane protein gene that are unique to SARS-CoV-2, a well-conserved region of the matrix gene of influenza A (Flu A target), the nonstructural protein 1 (NS1) gene of influenza B (Flu B target), and the matrix gene of RSV (RSV target). An Internal Process Control (IPC) is also included. The IPC is present to control for adequate processing of the target virus through all steps of the assay process and to monitor the presence of inhibitors in the RT-PCR processes. The sample to result time is approximately 20 minutes. en
