The presence of two bars on the test strip during the Neo-Crown antigen test proves that this antigen test result is positive. It can be regarded as a suspected New Crown Virus infection, and nucleic acid testing is needed to confirm the diagnosis. The new crown antigen test utilizes the principle of antigen-antibody reaction, but due to the large influence of the external environment and the limitations of the sensitivity and specificity of the reagent kit, it can only be used as a preliminary judgment, and cannot be used as the basis for a definitive diagnosis. The presence of two bars in the New Crown Antigen test is considered positive, and there is a high degree of suspicion that the organism is infected with the New Crown Virus (provided that false-positive results are excluded). In this case, it is recommended to go to the hospital for nucleic acid test to confirm the diagnosis. On the way to the hospital, you should pay attention to wearing masks and prohibit taking public transportation to avoid spreading the epidemic.
