Gelonghui, January 22丨The COVID-19 testing sector continued to be strong. Xilong Scientific opened and stopped, Jinyu Medical rose nearly 6%, and Matilda Biotech and Andy Diagnostics rose higher. The National Health and Health Commission said on the 20th that people returning home need to have a negative nucleic acid test certificate within 7 days before returning home. People returning home are not divided into high school and low risk areas, and they are responsible for their own expenses. Industry insiders believe that overall, the subsequent implementation of the Spring Festival return policy has provided an additional market of 10 billion dollars for manufacturers of nucleic acid testing products; for testing service providers, there is a market increase of 100 billion dollars. Guohai Securities believes that the global COVID-19 pandemic continues, and the spread of the winter epidemic is once again accelerating. Demand for nucleic acid detection kits has only increased unabated. With exports combined with a domestic two-pronged approach, the performance of participants in detection reagents and testing services is expected to continue to be highly elastic in 2021.
