A few days ago, the State Food and Drug Administration approved a number of new crown antigen self-test products for the market. The new crown antigen self-test product has been pre-ordered. Chinese residents can self-test at home without professional assistance, let alone machine intervention, and test results can be obtained within 15-20 minutes.

Antigen detection is convenient and fast, which is conducive to early triage and rapid management of suspected populations. The new crown antigen test cannot replace the nucleic acid test. If the self-test is positive, it should be reported immediately, and the nucleic acid test should be carried out according to relevant arrangements.

Antigen detection is generally used in the acute infection period, that is, the detection of samples within 7 days of the onset of symptoms in the suspected population. Both positive and negative antigen results of suspected populations should undergo further nucleic acid testing. Positive results can be used for early triage and rapid management of suspected populations, but cannot be used as the basis for the diagnosis of new coronavirus infection. In addition, the selected antigen detection reagents must be approved by the State Drug Administration.
