If both lines are light red, the test is considered positive, and patients are advised to go to a regular hospital for a nucleic acid test to determine the cause of the disease. Neocoronavirus antigen test is mainly a screening test for Neocoronavirus, which can only quickly screen for Neocoronavirus infection, but cannot replace the nucleic acid test.

Once the diagnosis of new coronavirus infection is confirmed, the patient should actively cooperate with the doctor to take relevant therapeutic measures, so as to avoid delaying the condition.
