This is a qualitative molecular test for the detection of nucleic acid of coronavirus 2 (SARS-CoV-2), Influenza virus types A and B and Respiratory Syncytial virus (RSV) in nasopharyngeal swabs from patients presenting with respiratory symptoms. Combination testing is most useful during periods when these viruses are in known circulation in the community. Patients may have mild to severe respiratory illness with symptoms of sore throat, cough, fever, headache, congestion or runny nose, shortness of breath and complications including pneumonia.
