COVID-19 Testing for Active Infection

COVID-19 is the name for the respiratory syndrome caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Sonora Quest test code 907080 - SARS-CoV-2 RNA (COVID-19), Qualitative, NAAT, is a qualitative molecular assay, which amplifies the RNA of the SARS-CoV-2 virus in human specimens such as nasopharyngeal or throat swabs (upper respiratory). Alternative specimens, including bronchial lavage/wash, or sputum/tracheal aspirate are also acceptable.

Detected results indicate presence of COVID-19 viral infection.

Not Detected results indicate no presence of COVID-19 viral infection.

An inconclusive result could indicate a sample with a viral concentration near the limit of detection of the test or other factors. An additional sample collection may be considered.

Sonora Quest Laboratories offers COVID-19 antibody testing. Click here for detailed information.

Physicians may order testing using test code 907080 - SARS-CoV-2 RNA (COVID-19), Qualitative, NAAT, through normal ordering processes. Any order for COVID-19 diagnostic testing must be submitted on a separate requisition and packaged separate from other tests.

Patients can visit SonoraQuest.com/OrderCovid to learn about options to order their own COVID-19 testing without an order from a healthcare provider.
