Results comparing on the internal control of RT-PCR on SARS-CoV-2 by two different nucleic acid extraction methods of releasant

Objective: Extraction of nucleic acid of SARS-CoV-2 with releasing agent by one-step method was optimized to improve the detection rate of the internal control (IC) in RT-PCR, reduce the re-examination rate caused by the non-detection of IC, and improve the time efficiency of report.
