Basic requirements for self-testing of novel coronavirus antigens
Applicable people The self-test of the new coronavirus antigen (hereinafter referred to as the antigen) is suitable for people who go to primary medical and health institutions and have symptoms such as respiratory tract and fever and have symptoms within 5 days; it is also suitable for quarantine observation personnel and community residents. Among them, people in home isolation, close contact and sub-close contact, entry isolation observation, closed control area and control area should conduct antigen self-tests under the organization and management of relevant management departments.
Self-testing instructions Antigen test is generally used in the acute infection period, that is, the sample test within 7 days of the onset of symptoms in the suspected population. Both positive and negative antigen results of the suspected population 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. The selected antigen detection reagents must be approved by the State Drug Administration.
Antigen self-test operation process
According to the instructions of the reagent, put the nasal swab after collecting the sample into the sampling tube immediately, and the swab head should be rotated and mixed in the preservation solution for at least 30 seconds. , to ensure that the sample is sufficiently eluted in the sampling tube. Step2: Squeeze the liquid of the swab head through the outer wall of the sampling tube by hand, and then discard the swab. After capping the sampling tube, drop the liquid vertically into the sample hole of the test card.
According to the reagent instructions, wait for a certain period of time to interpret the results.
Positive results: red or purple bands are displayed at both "C" and "T", and the color of the band at "T" can be dark or light, all of which are positive results. Negative Result: Red or purple band at "C", no band at "T". Invalid result: No red or purple band is displayed at "C", regardless of whether the band is displayed at "T". If the result is invalid, you need to take the test strip and test again.
