Abstract
The novel coronavirus 2019 (COVID-19) caused by SARS-CoV-2 spread rapidly worldwide, posing a severe threat to public life and health. It is significant to realize rapid testing and timely control of epidemic situations under the condition of limited resources. However, laboratory-based standardized nucleic acid detection methods have a long turnaround time and high cost, so it is urgent to develop convenient methods for detecting COVID-19. This paper summarizes the point-of-care testing (POCT) developed for novel coronavirus from three aspects: nucleic acid extraction, nucleic acid amplification, and detection methods. This paper introduces a commercial real-time detection system that integrates the abovementioned three steps and the matters needing attention in use. The primary purpose of this review is to provide a reference for emergency response and rapid deployment of COVID-19 and some other emerging infectious diseases.
