Diagnostic testing for SARS-CoV-2

Abstract

Testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) relies on reverse transcription polymerase chain reaction (RT-PCR), which amplifies SARS-CoV-2 genetic material.[1][1] Nasopharyngeal or oropharyngeal RT-PCR sensitivity is highest when performed early after symptom onset.[2][2
