COVID-19 (Coronavirus) SARS-CoV-2 Real-Time RT-PCR


SARS-CoV-2 RNA, Qualitative Real-Time PCR- The SARS-CoV-2 Real-Time RT-PCR test is a qualitative molecular diagnostics test that aids in the diagnosis of COVID-19.

This test is intended to be performed only using respiratory specimens collected from indvidules who meet CDC clinical and/ or epidemiological criteria for COVID-19 testing.

A Detected result is considered a presumptive positive test result for COVIS-19. This indicates that RNA from SARS-CoV-2 (Formerly 2019-nCov) was detected, and the patient is presumptively infected with the virus and presumed to be contagious. Presumptive positive and Inconclusive samples will be referred to Public Health for Conformation.

A NOT Detected (Negative) test result for this test means that SARS-CoV-2 RNA was not present in the Specimen above the limit of detection. However, a Negative result does not rule out the possibility of COVID-19 and should not be used as the sole basis for patient management decisions.
