Since the emergence of COVID-19 in late 2019, the gold standard in testing for the disease has been a nuclear-derived technique: real-time reverse transcription–polymerase chain reaction, or real-time ...
COVID-19 is commonly diagnosed by quantitative fluorescence real-time reverse transcriptase-polymerase chain reaction (qRT-PCR) (1, 2). The test is the sequential action of two enzymes–an ...
