New crown antigen testing is usually relatively accurate at over 95%.
Neocoronavirus antigen test is performed by inserting a swab into the nasal cavity or oral cavity to collect secretions, which are then added to a sample eluent, and the eluent is then dropped into a test card to detect the presence of neocoronavirus antigen. According to some available testing data, the accuracy of the novel coronavirus antigen test is more than 95%, and it is suitable for people who have the need for self-testing.
False-positive and false-negative tests exist in the New Crown Antigen Test, therefore, the New Crown Antigen Test is not a substitute for the New Crown Virus Nucleic Acid Test. If the antigen test is positive, the diagnosis of infection cannot be confirmed, and the nucleic acid test needs to be further improved, and only if the nucleic acid test is positive, the diagnosis of infection can be confirmed.
