The new crown virus nucleic acid test, currently need to be completed in the laboratory, can not be completed alone, and the new crown antigen test kit can be completed alone. Now there are new crown antigen test kits on the market, which can be purchased for use by the general public. The collected sample washing solution will be dropped into the test hole of the test card according to the requirements, and the result reading area of the test card will be observed within the specified time (generally the effective time is 15 minutes). The results are as follows: 1. Positive result: two red lines appear in the result reading area of the test card, one is the quality control line C line, and the other is the T line detection line. 2. Negative result: one red line appears in the result reading area of the test card, i.e., line C of the quality control line. 3. Invalid result: No red line is seen, or only the T test line is seen, but not the C test line. When the invalid result appears, use a new test card to test again, note that the interpretation of the result is valid within 15 minutes. False-negative or false-positive antigen tests may occur, and further nucleic acid testing is usually required for clarification.
