The new coronavirus antigen test is prone to false positives in the presence of some interference. Compared to nucleic acid test results, antigen test results are not as accurate. Therefore, if you have doubts about the results of the antigen test, you can improve the nucleic acid test to confirm the diagnosis. New Crown virus antigen test is detected through the combination of antigen and antibody reaction on a test strip, and the results are usually available in 15 to 20 minutes. However, the presence of some interferences may lead to false-positive results, and the accuracy of the results will be relatively low compared to the nucleic acid test results. If the new coronavirus antigen test result is positive, the patient should be referred to a medical institution such as a fever clinic for nucleic acid testing. If the neo-coronavirus antigen test result is negative, nucleic acid testing may be performed if there is a high suspicion of infection.
