Nucleic acid detection has become the norm. Can antigen testing replace nucleic acid testing? Who can do that?

Novel coronavirus antigen test is a 20 19 coronavirus disease screening test, which can be used to screen specific population and improve early detection ability. Novel coronavirus antigen self-test is suitable for isolating observers and community residents. Among them, people who are isolated at home, in close contact and sub-close contact, in quarantine observation at entry, and in closed control areas shall carry out antigen self-inspection under the organization and management of relevant administrative departments.

Novel coronavirus 20 19 coronavirus disease The detection of 20 19 coronavirus disease cannot replace the detection of CVID- 19 nucleic acid, but it is still the basis for confirming novel coronavirus infection. In the process of nucleic acid detection and confirmation, if the nucleic acid test is positive, no matter whether the antigen test result is positive or negative, corresponding measures will be taken according to novel coronavirus infection or coronavirus pneumonia-19 confirmed infection; If the nucleic acid test is negative, but the antigen test is positive, the infected person should be regarded as a novel coronavirus patient, and the nucleic acid should be closely observed and continuously detected.

"novel coronavirus antigen test can be used as a supplementary test to screen specific populations, which helps to improve the ability of' early detection'." Li said that the emergence of highly contagious variants like Omicron has brought challenges to epidemic prevention and control. By carrying out antigen detection in grass-roots areas where nucleic acid detection is impossible, or in centralized and isolated places with relatively high infection risk, the source of infection can be found in a short time without special laboratories and complicated instruments. This can reduce the working intensity of nucleic acid sampling and testing personnel, and can also be used as a means of virus detection.
