Molecular Diagnosis of COVID-19

Roshan Niloofa, Suranjith L Seneviratne, Akila Cooray, Nilanthi Senanayake, Ishan De Zoysa


The SARS-CoV-2 coronavirus causes COVID-19. Nucleic acid amplification tests (NAAT), could be used to detect the presence of SARS-CoV-2 viral RNA in clinical samples. Several real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) assays are being used by many laboratories for confirming COVID-19. We have outlined the characteristics of the available SARS-Cov-2 rRT-PCR assays and discussed its clinical utility.
