At 10:00 a.m. on March 24, Shanghai held a press conference on epidemic prevention and control. Yu Zhonghua, deputy mayor of Changzhen, introduced the latest situation of the epidemic in the city.
A reporter asked: Can public medical institutions in this city provide new coronavirus antigen testing services? When citizens go to the hospital, under which conditions should nucleic acid testing be performed, and under which conditions can antigen testing be performed?
Wu Jinglei introduced that recently, the National Health and Health Commission issued the “New Coronavirus Antigen Detection Application Plan (Trial)”. An important feature of antigen detection is that it is fast and simple, which can help improve the ability of early detection of cases. It is an important feature of antigen detection. An important addition to nucleic acid testing. Compared with the two methods, antigen detection is convenient and fast, but the sensitivity is slightly lower; nucleic acid detection is relatively complex, and the detection time is long, but the sensitivity and specificity are relatively high, so it is used as a diagnostic method. Nucleic acid testing is still the basis for the diagnosis of new coronary pneumonia infection, and a negative antigen test cannot replace a negative nucleic acid certificate.
Wu Jinglei introduced that, based on the characteristics of antigen detection and nucleic acid detection, in order to give full play to the advantages of antigen detection, and to grasp and discover people who are positive for antigen detection faster and more fully, antigen detection work is mainly carried out in specific groups or collective units. Organizationally, once abnormal test results occur, nucleic acid test review will be carried out immediately. At present, antigen testing is mainly used in conjunction with nucleic acid screening. If there is supply in the market in this city, the operation must be carried out in strict accordance with the product instructions. Once the test results are abnormal, they should be reported immediately, and go to the fever clinic for nucleic acid testing according to the standardized procedures. (Reporter Zou Jiawen)
