How to judge whether it is nucleic acid detection or antigen detection?

This is an antigen test. There is a pink bar at the bottom and a pink bar at the top, which means it is positive.

It is convenient and quick to detect COVID-19 antigen on the test paper through the binding reaction between antigen and antibody, and the result can be obtained in 15-20 minutes. However, the antigen-antibody reaction will be false positive due to some interference, and the specificity of the method can not reach 100%. Therefore, the antigen test results cannot replace the nucleic acid test results.

1. If the antigen test is positive, residents should immediately report to their communities (towns and villages) whether they have symptoms such as respiratory tract and fever, and the communities (towns and villages) should contact the emergency center and transport the residents to medical institutions with fever clinics for nucleic acid detection according to the guidelines for transporting personnel related to the COVID-19 epidemic. Sampling swabs, sampling tubes and inspection cards used by positive personnel are put into sealed bags and transported to medical institutions for medical waste disposal.

2 asymptomatic residents with negative antigen test can be closely observed, and antigen test or nucleic acid test can be carried out when necessary; Residents with symptoms are advised to go to medical institutions with fever clinics for nucleic acid testing as soon as possible; If it is inconvenient to see a doctor, you should be isolated at home, avoid going out for activities, and conduct antigen self-test once a day for 5 consecutive days.
