Neocoronavirus antigen refers to a test for neocoronavirus antigen, and a weakly positive test result usually indicates infection with a new coronavirus. Neocoronavirus antigen is less sensitive and less specific than nucleic acid tests, but it is still effective in detecting neocoronavirus infections, and a weak positive test result usually indicates infection with a neocoronavirus. However, for some patients, a weak positive test may be a false positive, and further detailed examination is required. For patients with a weakly positive test for the new coronavirus antigen, further nucleic acid testing or CT of the lungs or new coronavirus antibody testing may be performed to determine whether they are infected with the new coronavirus. For those who are confirmed to be infected, they should adjust their mentality and actively cooperate with the doctor for isolation treatment, so as to improve the accompanying uncomfortable symptoms of the organism and promote the restoration of the organism’s health. It is recommended that those who are weakly positive for the new coronavirus antigen test should report to the community in a timely manner so that further relevant treatment measures can be taken.
