Antigen testing currently refers to the Neocoronavirus antigen test. Two bars on the antigen test is not a confirmed diagnosis, it is a positive initial screen, and a nucleic acid test is also required.
If you do a self-test for Neocoronavirus antigen and you get a two bar result, it means that the antigen test is positive, suggesting that you may be infected with Neocoronavirus. However, this does not confirm the diagnosis. Since the antigen self-test needs to be self-administered, there may be specimen contamination during the sampling and experimentation process, as well as false positives on the test strips.
In this case, nucleic acid testing should be performed in a timely manner, and the results of the nucleic acid test will prevail. If the result is negative, it means that the antigen test has a false-positive result.
If it is positive, it means new coronavirus infection, which requires centralized isolation, further diagnosis and typing after re-testing and expert group research.
