The New Crown Antigen Test must wait 15 minutes for a more accurate result. The New Crown Antigen test is a relatively convenient and quick test at present. The nasal swab is put into the reagent, and the reagent needs a certain amount of time to finish reacting with the sample taken from inside the nasal swab, and the whole process takes about 15 minutes. The whole process takes about 15 minutes. Therefore, it is usually necessary to wait for 15 minutes to get a more accurate result, and if the time is less than 15 minutes, the result may be inaccurate. Although the antigen test results are very fast, but only for personal self-testing, the accuracy is not as high as that of the nucleic acid test, so nowadays more formal occasions require proof of nucleic acid test to be able to go in and out normally. If the antigen test result is positive after 15 minutes, the patient should be reported to the community in time, and then isolated in a single room, waiting for the community staff to contact the emergency center to send staff to transfer them to the fever clinic to do nucleic acid test.
