In order to further optimize the new coronavirus detection strategy, the comprehensive group of the joint prevention and control mechanism of the State Council recently decided to add antigen detection as a supplement to nucleic acid detection. Compared with nucleic acid detection, antigen detection can be faster and more convenient to operate, but with lower accuracy, it is generally used in the early stage of infection. On March 15, Zhang Chen, assistant director of the Medical Laboratory Department of Zhongda Hospital Affiliated to Southeast University, demonstrated the method of antigen detection.
According to the “New Coronavirus Antigen Detection Application Plan (Trial)” that has been formulated and issued, the applicable groups of antigen detection are: First, those who go to primary medical and health institutions for treatment, have respiratory symptoms, fever and other symptoms and have symptoms Persons within 5 days; second, quarantine observation personnel, including home quarantine observation, close contact and sub-close contact, entry quarantine observation, closed control area and personnel in control area; third, community residents who need antigen self-testing.
