WebTotal RNA (1 mg) was reverse transcribed using a cDNA synthesis kit (Roche Diagnostics, Indianapolis, IN, USA) with anchored-oligo (dT) 18 primers. Quantitative PCR was performed under standard conditions using an Eppendorf real-time PCR machine and an SYBR Green I Master Kit (Roche Diagnostics). WebPCR tests are generally considered better at detecting the presence of the SARS-CoV-2 virus and are currently the gold standard for diagnosis of COVID-19. PCR assays typically take several hours (including specimen processing time) to generate results and require complex laboratory equipment and trained technicians.
