 Results in 8-15 minutes: the new rapid detection kit for coronavirus nucleic acid has been evaluated


It is reported that the rapid nucleic acid isothermal amplification detection kit has completed clinical evaluation in the First Affiliated Hospital of Zhejiang University Medical College (92 clinical specimens), Zhejiang Provincial Center for Disease Control and Prevention (104 clinical specimens) and Jiangsu Provincial Center for Disease Control and Prevention (100 specimens), respectively.

The significance of rapid detection lies in early detection of virus, which is very important for blocking virus. In an interview with the financial client of Xinhua Daily, Wang Zhihong, chairman of Qitian gene, said that before that, it took 90 minutes for PCR (polymerase chain reaction) kit to detect the new coronavirus. Therefore, the rapid detection kit that can produce results in 8-15 minutes not only breaks this bottleneck, but also becomes one of the shortest detection kits at present. The key to this breakthrough lies in the core technology. Wang Zhihong said that the RAA (recombinant enzyme mediated isothermal nucleic acid amplification) technology used in the rapid detection kit developed by the team is a relatively new technology in the field of nucleic acid detection technology.

At present, the scope of application of the kit is in the municipal laboratory. According to the latest information from the Institute of viral disease prevention and control of China Center for Disease Control and prevention, the approval number of the kit is being applied for by the drug administration. Wang Zhihong said that although the detection kit has been developed, there is still a process to the practical application stage, the most important thing is to let users really master the operation of the instrument and equipment, Wang Zhihong said, we have worked so hard to develop it, in fact, we have completed 20%, and 80% of the latter is going to land. Therefore, at present, enterprises are organizing long-distance teaching and conducting unified training for experimental personnel, so that the products can not only be used, but also play a real role. Extended reading for 8-15 minutes results: the new rapid detection kit for coronavirus nucleic acid has completed the evaluation of 300 lung CT images of the artificial intelligence pneumonia auxiliary diagnosis system, and solved in 10 seconds. Nearly 20 million people in four months in the United States have been infected with influenza this year or in the past 10 years.
