Science and Technology Daily, Wuhan, March 31 (Reporter Liu Zhiwei Correspondent Gao Xiang) The time for the rapid detection of the new coronavirus can be shortened to 20 minutes. On the 31st, the Medical Research Institute of Zhongnan Hospital of Wuhan University announced the team led by the hospital Yin Hao and Zhang Ying. Collaborated to develop a new rapid nucleic acid detection method for new coronavirus, which was published online in the latest issue of "Nature Biomedical Engineering".
In the context of the continuous spread of the new coronavirus and its mutant strains, rapid screening is very important for pathogen detection and control of the spread of the epidemic.
At present, the country adopts the RT-qPCR new coronavirus detection method, also known as the gold standard of detection.
Since this method relies on the use of professional laboratory instruments and professional operation, it takes about 6 hours from sampling to result.
The research group of Prof. Yin Hao and Prof. Zhang Ying from the Medical Research Institute of Zhongnan Hospital of Wuhan University and the Frontier Science Center of Immunity and Metabolism of the Ministry of Education has developed a new nucleic acid rapid detection method sPAMC, which has high sensitivity, high specificity and convenient operation. and fast features.
The researchers used this method to detect a total of 204 throat swab samples, and achieved 94.2% accuracy in the real samples of the new coronavirus without any false positives. The virus can be detected in only 20 minutes, and the portable UV lamp or blue light can be used. The results are observable and the convenience of detection is greatly improved.
