Since the outbreak of the new crown epidemic in 2020, the epidemic has repeatedly jumped between the outbreak and the control. Whether in the community or in the hospital, people can be seen queuing up in front of the nucleic acid test sampling point, and the "pain mask" of being stabbed in the throat by the doctor Scenes. According to the National Bureau of Statistics, by the end of 2021, a total of 11,937 medical and health institutions across the country will provide nucleic acid testing services for the new coronavirus, with a total testing capacity of 41.68 million copies per day. More than 400 million people have been tested. It can be said that nucleic acid testing has become a part of people's lives.

my country's nucleic acid testing market is growing rapidly. In 2019, the global nucleic acid testing market size reached 8.5 billion US dollars, and China accounted for 18%, about 10.6 billion yuan. By 2022, China's nucleic acid testing market size is expected to reach 14.6 billion yuan. Various new nucleic acid detection instruments have also sprung up. For example, the fully integrated new coronavirus nucleic acid detection mobile laboratory, which was turned into a "light cavalry" by Academician Zhong Nanshan, is only a yellow passenger car in appearance, but it can collect nucleic acid extraction. , nucleic acid sampling, nucleic acid amplification, nucleic acid detection and integration, the results can be obtained in 45 minutes, and it has become an epidemic prevention tool for the Spring Festival Gala and the Winter Olympics.
