An Ultra-Rapid Real-Time RT-PCR Method Using the PCR1100 to Detect Severe Acute Respiratory Syndrome Coronavirus-2

Jpn J Infect Dis. 2021 Jan 22;74(1):29-34. doi: 10.7883/yoken.JJID.2020.324. Epub 2020 Jun 30.

Abstract

The disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in Wuhan, China, in December 2019, has rapidly spread worldwide. SARS-CoV-2 is usually detected via real-time reverse-transcription polymerase chain reaction (RT-PCR). However, the increase in specimen load in institutions/hospitals necessitates a simpler detection system. Here, we present an ultra-rapid, real-time RT-PCR assay for SARS-CoV-2 detection using PCR1100 device. Although PCR1100 tests only one specimen at a time, the amplification period is less than 20 min and the sensitivity and specificity match those of conventional real-time RT-PCR performed on large instruments. The method is potentially helpful when daily multiple SARS-CoV-2 testing is needed, for example to confirm virus-free status prior to patient discharge.

Keywords: PCR1100; severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2); ultra-rapid real-time RT-PCR.
