Generally, it is possible to turn negative after being positive for neocoronary antigen, and the exact time to turn negative is related to the condition and individual factors.
When the antigen test is positive, and the nucleic acid test confirms the positive diagnosis, for asymptomatic infected people or people with mild symptoms, the virus can be cleared with the help of autoimmunity, and after the virus is cleared, the antigen test may turn negative. For people with severe symptoms who improve after symptomatic treatment, the antigen test may also become negative if there is no new coronavirus in the body.
If the antigen test is positive, it is recommended to report the case to the community and have nucleic acid testing done as soon as possible to confirm the diagnosis. If the test is positive, there is no need to be anxious. One should take rest, keep an optimistic and positive mindset, and improve one’s immunity in order to clear the virus and turn negative as soon as possible.
