The do-it-yourself nucleic acid thing is called the Neocoronavirus Antigen Test.
The Neocoronavirus antigen test is done by combining antigen and antibody reactions on a test strip, which is convenient and quick, and the results are usually available in 15-20 minutes. However, the antigen-antibody reaction is false-positive because of the presence of some interference, and the methodological specificity is less than 100%. Therefore, antigen test results cannot replace nucleic acid test results.
What to do after antigen testing.
Whether the test result is negative or positive, the used-up novel coronavirus antigen kit needs to be disposed of according to medical waste, and can be sterilized with alcohol first if possible.
