Analytical sensitivity and efficiency comparisons of SARS-COV-2 qRT-PCR assays

Currently, several quantitative reverse-transcription polymerase chain reaction (qRT-PCR) assays are being used by clinical, research, and public health laboratories for rapid detection of the virus. However, it is currently unclear if results from different tests are comparable. This study’s goal was to evaluate the
primer-probe sets used in four common diagnostic assays available on the World Health Organization (WHO) website.
