Generally, a COVID-19 antigen test refers to testing for the SARS-CoV-2 virus and can be used to determine whether an individual is infected with the novel coronavirus. This test is characterized by its speed, convenience, and simplicity. The specific steps are as follows:
1. Wash your hands thoroughly before starting and clean the nasal cavity.
2. Remove the nasal swab, tilt your head backward, insert the swab into the nostril, gently rotate it against the inner nasal wall for four full turns, then remove it.
3. Place the swab into the prepared sample tube and stir by rotating it for 30 seconds.
4. Securely cap the sample tube, then vertically dispense the liquid into the specimen well of the test cartridge.
5. Wait 15 minutes before reading the result: if a red or purple band appears only at the C region, the result is negative; if bands appear at both the C and T regions, the result is positive; if a band appears only at the T region, the result is invalid.
If this test is needed, to ensure accuracy, it is recommended to visit a reputable medical facility and perform the test under the guidance of a qualified healthcare professional. If the result is positive, prompt medical consultation is advised to avoid delays in treatment.
