Beijing nucleic acid testing organization expanded to 124, the largest daily detection capacity increased to 230,000

Yesterday, at a press conference on the prevention and control of the new coronavirus pneumonia epidemic in Beijing, Gao Xiaojun, a spokesman for the Municipal Health and Health Commission, said that after the outbreak in the new development market on June 11, the city rapidly expanded its nucleic acid detection capabilities. On November 20, the number of nucleic acid testing institutions has been expanded to 124, and the maximum daily testing capacity has been expanded to 230,000.

Gao Xiaojun introduced that in mid-January this year, the 17 disease prevention and control centers in the city all have nucleic acid detection capabilities. In early February, there were 10 tertiary hospitals equipped with nucleic acid detection capabilities. From March to April, the number of nucleic acid testing institutions in Beijing has gradually increased. By the end of April, 61 institutions can carry out testing, with a daily testing capacity of 47,000 copies. In early June, Beijing's nucleic acid testing institutions had reached 98, with a daily testing capacity of 100,000 copies. After the epidemic occurred in the newly developed market, the city rapidly expanded its nucleic acid detection capacity. As of June 20, the number of nucleic acid detection institutions had been expanded to 124, and the maximum daily detection capacity was expanded to 230,000. Of the 124 institutions currently conducting nucleic acid testing, there are 20 CDCs, 73 second- and third-level hospitals, and 31 medical laboratory laboratories. If the 5:1 mixed inspection method is adopted, nearly 1 million people can be tested every day.According to the relevant requirements, second-level general hospitals should have the ability to detect nucleic acids. According to reports, as of June 20, of the city's 39 second-level general hospital nucleic acid testing laboratories, 15 already have testing capabilities, 12 are under review, and 12 have not yet submitted applications. The completion status of the second-level general hospitals in each district with nucleic acid detection capacity showed that the completion rate of the five districts of Shijingshan, Mentougou, Changping, Shunyi, and Yanqing was 100%, the completion rate of the three districts of Dongcheng, Chaoyang, and Huairou was 50%, and the completion rate of Fengtai District 29%, Haidian District completion rate is 25%, Xicheng District completion rate is 20%, Fangshan, Daxing, Pinggu and Miyun districts have zero completion rate. There is no secondary general hospital in Tongzhou District and Economic and Technological Development Zone. Jingshun Hospital in Shunyi District has been unable to have the ability to detect nucleic acid in the near future, and has applied for adjustment as a first-class hospital, which has been approved by the Shunyi District Health Committee.Hot response:1. For close contacts of confirmed cases, the first nucleic acid test is negative, do they need to be isolated?Li Jinming, a researcher at the Clinical Testing Center of the National Health and Health Commission: The close contact of confirmed cases of new coronary pneumonia is negative for the initial nucleic acid test, and isolation is still required. Close contacts have a much higher risk of infection than non-close contacts. During quarantine, close contacts will need to be tested for nucleic acids once they have symptoms; if symptoms do not appear during quarantine, they will need to be tested for nucleic acids again and the result will be negative to release the quarantine.2. Can nucleic acid test "false negative" be avoided?Li Jinming, a researcher at the Clinical Inspection Center of the National Health and Safety Commission: "False negatives" cannot be completely avoided. Factors such as the timing of sampling, sample type, and laboratory testing will affect the accuracy of nucleic acid testing.A positive nucleic acid test is the gold standard for viral infections, but there are also some "false positives", such as those caused by residual contamination, which can be avoided by retesting positive samples."False negatives" cannot be completely avoided. For example, the timing of specimen collection, the early stage of infection of the close contact, and whether the onset is relatively long. This is not accurately detected by nucleic acid detection. The end of the incubation period of infection or early-onset may also be A "false negative" appears. Whether the sampling method is standard or whether the virus is mutated will affect the accuracy of nucleic acid detection.
