Where to check？ How to check？ The reporter visited the whole process of nucleic acid testing service in Beijing

　　Xinhua News Agency, Beijing, April 22 (Reporter Wang Junlu, Xia Ke) In order to strengthen the prevention and control of normalized epidemic situation, Beijing has expanded the scope of nucleic acid testing, and implemented due diligence for key populations and voluntary diligence for other populations. Recently, the reporter visited the first batch of nucleic acid testing sites in Covid-19 announced by the Beijing Municipal Health and Health Commission, and visited the whole process of personal nucleic acid testing.

　　Where to check? Is it convenient and safe?

　　On the morning of 17th, the reporter saw outside the east gate of Beijing Yizhuang Biomedical Park that the sampling area of Beijing Boao Medical Inspection Institute was set in a temporary tent, and the front and rear curtains of the tent were opened to ensure ventilation. The scene was divided into two queues: individuals and groups, with more than ten citizens waiting in line. A number of staff wearing protective clothing maintained the order of the scene and put a one-meter sign on the ground to guide everyone to keep the queue distance.

　　Under the guidance of the staff, the person to be tested fills in the test application form and scans the code for online information input, and obtains the tongue depressor and sampling swab needed for nucleic acid sampling. After the online information is submitted, the person to be inspected will receive a confirmation message. After the on-site staff checks the identity information and pays the inspection fee, they can enter the inspection point for sampling.

　　Wang Guoqing, vice president of Beijing Boao Jingdian Biotechnology Co., Ltd., introduced that the company mainly provided nucleic acid testing services for medical institutions. Since April 12, Beijing has required visitors to Beijing to provide health certificates with negative nucleic acid testing within 7 days. There are more and more individuals with testing needs, and currently about 1,000 cases are tested every day.

　　"In order to ensure the safety of sampling, we set up sampling points outdoors, and the sampling points are ventilated before and after, and it is strictly required that only one person can sample at a time, and the staff will disinfect the site every time." Wang Guoqing said.

　　It is understood that at present, the number of nucleic acid testing institutions in Beijing has increased from 17 in early February to 50. Departments, units and individuals with testing needs can inquire through the official website of the Beijing Municipal Health and Health Commission and the official WeChat "Healthy Beijing".

　　How to check? Where’s the sample?

　　The reporter saw in the sampling area of Beijing Boao Medical Inspection Institute that the staff took out the swab from the material bag, wiped it several times at the throat of the person being tested, and then put the sample into a special sample collection tube. The whole sampling process took less than 1 minute.

　　After the sampling is completed, the samples will be stored in a special sample transfer box and sent to the secondary biosafety molecular testing laboratory. Bai Xinghua, director of the Pathogenic Microbiology Room of Beijing Boao Medical Laboratory, said that after the inspectors take out the sealed samples in the biosafety cabinet and confirm that they are intact and leak-free, they should first inactivate them, then extract nucleic acids, and finally add detection reagents such as primers and enzymes, and conduct fluorescent PCR detection in the amplification instrument.

　　Bai Xinghua introduced that if the sample contains Covid-19, with the progress of the amplification reaction, the detection system can observe a significant increase in fluorescence signal, so as to determine whether the subject is infected. Subsequently, the examinee can query the test report online.

　　The reporter learned that most of the people who came to test were people who came to Beijing from other places to return to work, and some of them were people who came to Beijing for business trips and stayed in hotels. "I just returned to Beijing from Xi ‘an, ready to go back to work in the factory, and the factory asked us to provide proof of nucleic acid testing." Mr. Ma, who came to test, said.

　　On the afternoon of the 21st, the reporter saw in the screening clinic on the first floor of the north side of Building A of Beijing You ‘an Hospital that there were more than ten people waiting in line for testing. "The workers in the unit are all coming back from all over the world. If you do a nucleic acid test, everyone can feel more at ease with each other." Mr. Cheng from Shandong said.

　　Tip! What should I pay attention to before testing?

　　The reporter learned that in order to further implement the general requirements of "external defense input and internal defense rebound" and promote nucleic acid testing, the Beijing Leading Group for Epidemic Prevention and Control clearly implemented nucleic acid testing for eight categories of personnel. With the continuous promotion of returning to work and production and the related requirements of staying in hotels, more and more people are facing the need of nucleic acid testing.

　　Deng Tao, director of medical inspection department of Beijing Boao Jingdian Biotechnology Co., Ltd., said that the common detection methods for Covid-19 are nucleic acid detection and antibody detection. The target molecule of nucleic acid detection is a unique gene fragment in Covid-19. Covid-19 can be detected earlier after infection, which is beneficial to early detection and early reporting, so as to isolate and treat early and avoid further spread of the epidemic.

　　What are the precautions before nucleic acid testing? Wang Guoqing suggested that we should first understand the nucleic acid detection process in advance; Secondly, be sure to bring personal valid documents such as ID cards; Third, make an appointment in advance as far as possible to avoid people getting together at the scene and gathering risks.

　　Gao Xiaojun, spokesman of Beijing Municipal Health and Health Commission, said that under the premise of ensuring biological safety and quality of inspection and testing, Beijing encourages and supports more medical and health institutions and inspection and testing institutions to carry out Covid-19 nucleic acid testing, and Beijing Municipal Health and Health Commission will update the relevant changes of testing institutions in a timely manner.
