Reverse transcriptase quantitative real-time PCR (RT-qPCR)
detection of COVID-19 patients
The average Ct values of COVID-19 subjects was 31.1±7.4 (min =
15.7, max = 40.5). The majority of the subjects (83.1%, 69/83) were
positive by RT-qPCR and 16.8% (13/83) were negative. As shown inTable 2, according to the Ct values, 29 (42%), 29(42%)
and 11 (15.9%) subjects have strong, moderate and weak RT-qPCR positive
results.
