1. Wash your hands.
2. The antigen test card should be unpacked and placed in a flat and clean place.
3. Sample collection. Carefully open the outer package of the nasal swab to avoid hand contact with the swab head. Then tilt your head slightly, hold a cotton swab at the tail of one hand and stick it to one nostril, then slowly penetrate back to 1- 1.5 cm along the bottom of the inferior nasal passage, then stick it to the nasal cavity and rotate it for at least 4 times (the residence time is not less than 15 seconds), and then repeat the same operation on the other nasal cavity with the same cotton swab.
Residents with negative antigen test and no symptoms 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.

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. ?
On March, 2022, 1 1, the Application Scheme for Antigen Testing in COVID-19 (for Trial Implementation) was released. As of April 65438, 2003, the State Administration of Pharmaceutical Products has approved 27 kinds of COVID-19 antigen detection reagent products.
If the antigen test is positive, regardless of whether there are symptoms such as respiratory tract and fever, residents should immediately report to their communities (towns and villages), and the communities (towns and villages) should contact the emergency center, and transport the residents to medical institutions with fever clinics for nucleic acid testing according to the transportation guidelines of relevant personnel in COVID-19.
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.
