Interpretive Data
This test should be ordered for the detection of the 2019 novel coronavirus SARS-CoV-2 in individuals who meet SARS-CoV-2 clinical and/or epidemiological criteria.
The Coronavirus SARS-CoV-2 (COVID-19) by nucleic acid amplification test is for in vitro diagnostic use under the FDA Emergency Use Authorization (EUA) for U.S. laboratories certified under CLIA to perform high complexity tests. This test has not been FDA cleared or approved. In compliance with this authorization, please visit https://www.aruplab.com/infectious-disease/coronavirus for more information and to access the applicable information sheets.
Not Detected results do not rule out the presence of PCR inhibitors in the patient specimen or assay-specific nucleic acid in concentrations below the level of detection by the assay.
Detected results are indicative of the presence of SARS-CoV-2 RNA. Due to the complexity of nucleic acid amplification methodologies, there may be a risk of false-positive results. Clinical correlation with patient history and other diagnostic information is necessary to determine patient infection status.
Reliable results are dependent on adequate specimen collection, transport, storage, and handling.
