INTENDED USE

The Alinity m Resp-4-Plex assay is a multiplex real-time reverse transcription (RT) polymerase chain reaction (PCR) test intended for the qualitative detection and differentiation of RNA from influenza A virus (flu A), influenza B virus (flu B), Respiratory Syncytial Virus (RSV), and SARS-CoV-2 in nasopharyngeal (NP) swab specimens collected by a healthcare provider, from individuals with signs and symptoms of respiratory tract infection.

Results are for the identification and differentiation of RNA from flu A, flu B, RSV, and SARS-CoV-2. flu A, flu B, RSV, and SARS-CoV-2 RNA are generally detectable in nasopharyngeal swab specimens during the acute phase of infection. Positive results are indicative of the presence of flu A, flu B, RSV, or SARS-CoV-2 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 viruses. The agent detected may not be the definite cause of disease.

The Alinity m Resp-4-Plex assay is not intended to detect influenza C virus infections.

Negative results do not preclude flu A, flu B, RSV, or SARS-CoV-2 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 epidemiological information.

The Alinity m Resp-4-Plex assay is intended for use by qualified and trained clinical laboratory personnel specifically instructed and trained in the techniques of real-time PCR and in vitro diagnostic procedures.

INTENDED USER

The intended users for the Alinity m Resp-4-Plex assay are laboratory and healthcare professionals.
