[Explanation] In the outbreak of New Coronary Pneumonia in 2020, in addition to the medical workers who are fighting on the "front line", there is a group of people closest to the virus-New Coronavirus nucleic acid detector. Their test results are one of the important criteria for determining whether an individual is infected with new coronavirus. Because of the high-risk nature of the job, this "new occupation" has aroused public attention. Recently, the Ministry of Human Resources and Social Security announced 10 new occupations to be listed, among which nucleic acid detectors are listed. How to detect nucleic acid? What are the prospects for this new career?
[Commentary] On May 29, in the laboratory of the Center for Disease Control and Prevention of Chenghua District, Chengdu City, Sichuan Province, staff member Shi Haoyu was wearing double-layer protective clothing, wearing medical-grade N95 masks and goggles, and proceeded carefully on the operating table. Work on testing. After preparing the reagents, he transferred the inactivated samples into a special reaction tube with a sample gun. Then, the gene amplification is carried out by the fluorescent quantitative PCR instrument ... It takes 4 to 5 hours for a sample from entering the laboratory to obtain the final test result. Because it is very easy to produce aerosol during the detection process, it threatens the safety of the inspectors. Therefore, the inspectors perform a high-level "personal protection of the third-level laboratory". At the same time, in order to ensure the stable airflow in the laboratory, the opening of independent air conditioners should be minimized in the laboratory. In the gradually hot weather, the inspector's work has become more and more difficult.
[Same period] (Shi Haoyu, a staff member of the Inspection Section of the Chenghua District Center for Disease Control and Prevention, Chengdu) The test team we established, including our sampling team, our comrades were on standby and attacked for 24 hours. Often it is to work continuously and continuously. Whether it is a laboratory or sampling, we use a three-level protection. In this case, winter is actually okay. After the weather is getting hotter, we will enter the experimental area every time, or when sampling. Feeling of heat stroke.
[Commentary] It is understood that at present, there are 4 inspectors in the inspection department of the center responsible for the detection of new coronavirus nucleic acid, and 7 other inspection technicians carry out sample collection and other work. Speaking of the proposed new occupations announced recently, Shi Haoyu frankly stated that as the inspection personnel in the CDC, nucleic acid testing is already included in daily work. Except for special circumstances, there may not be more detailed inside the center Of the division.
[Same period] (Shi Haoyu, a staff member of the Inspection Section of the Chenghua District Center for Disease Control and Prevention, Chengdu) If we are our identity, we are the inspection technicians of the (hygiene) inspection technology. Because we will do many other tests besides nucleic acid detection. Mainly involves some testing in public places, food, infectious diseases, etc.
[Explanation] As a third-party testing organization approved to carry out nucleic acid testing of the new coronavirus, Sichuan Jinyu Medical Testing Center Co., Ltd. mainly provides medical testing services to medical institutions in Sichuan Province. Since the outbreak of the epidemic, more than 130,000 cases of nucleic acid testing have been completed by more than 200 inspectors in the company's testing department in Sichuan. For the "new occupation" nucleic acid inspector, Huang Ping, deputy general manager of the company, believes that this will put more emphasis on the professionalism of the inspectors and enhance the work requirements.
[Same period] (Huang Ping, deputy general manager of Sichuan Jinyu Medical Laboratory Center Co., Ltd.) First of all, it is actually difficult for them. Because most inspectors do not have this experience, there is no theoretical basis. I think that after this came out, it has emphasized and strengthened the professionalism of genetic testing and improved this requirement, which is more standardized and systematic. In the past, especially for some hospitals below Grade 3B, because many hospitals may not have this ability and no such energy (resources). After it is clearly proposed in this way, it may be more standardized by the time, so these hospitals can train some such personnel and build some platforms to deal with similar emergencies like the new crown.
[Explanation] Huang Ping believes that the application level of nucleic acid detection will become wider and wider in the future, and the emergence of nucleic acid detectors will further refine the professional division of labor. As an enterprise, they also need to reserve such professional and technical personnel.
[Same period] (Huang Ping, Deputy General Manager of Sichuan Jinyu Medical Testing Center Co., Ltd.) The necessity of specializing in nucleic acid is definitely because of the gene. I just said that this gene is mentioned, the application level of the gene It will be more and more extensive. Now that viruses and tumors are inherited, it may have many diseases in the future, and it will test its genes. Therefore, the importance of this nucleic acid detector will become more and more prominent. As long as there are such people, we definitely need them. In addition to responding to this new crown event, we have to reserve (resources) in the future, because like this large-scale epidemic, like this viral outbreak, I think it There is a certain periodicity, it does not mean that this new crown will not happen again after it comes out, so it is always valuable to him.
