SARS-CoV-2 RNA (COVID-19), Qualitative NAAT - The SARS-CoV-2 RNA (COVID-19), Nucleic-acid Amplification Test (NAAT) is a qualitative multi-target molecular diagnostics test that aids in the detection of COVID-19. This test is intended to be performed on respiratory specimens collected from individuals who meet the Centers for Diseases Control and Prevention (CDC) clinical and/or Epidemiological criteria for COVID-19 testing.

Influenza is an acute viral disease that is seasonal in incidence, occurring in the colder months. The illness classically presents with sudden onset of fever, chills, headache, myalgia and a non-productive cough. Influenza A or B virus cause the majority of clinically significant disease, with influenza C virus being responsible only for mild, predominately upper respiratory tract illness. Patients who present with suspected influenza may benefit from treatment with antiviral agents. Since the therapeutic options have expanded to include options for the treatment of influenza B disease, it is important to rapidly distinguish influenza A from influenza B in order to allow physicians a choice in selective antiviral intervention. This will also allow for the appropriate preventative intervention to be taken in institutions where measures can be taken for susceptible individuals. It is therefore important to not only rapidly determine whether influenza is present, but also which type of influenza virus is present.

Respiratory Syncytial Virus (RSV), Immunoassay - Respiratory Syncytial Virus (RSV) is considered the single most important virus affecting infants and young adults causing acute lower respiratory tract illness, mainly bronchiolitis and pneumonia. Adults are susceptible to infection but usually experience mild respiratory tract illness. Elderly patients may suffer severe lower respiratory tract disease.
