Ct values of sputum and NPS & OPS specimens in the real-time RT-PCR positive group (N=320)

Sputum NPS & OPS P-value
E gene 22.9±5.7 21.4±6.1 <0.01
RdRP gene 24.3±5.5 22.8±5.9 <0.01
N gene 26.0±5.6 24.3±5.8 <0.01

Values are presented as mean±standard deviation.

Ct, cut-off cycle threshold; NPS, nasopharyngeal swabs; OPS, oropharyngeal swabs; RT-PCR, reverse transcription polymerase chain reaction; E gene, envelope gene; RdRP gene, RNA dependent RNA polymerase gene; N gene, nucleocapsid gene.

P-value by paired t-test.
