How to test for COVID-19 antigen
Under normal circumstances, a COVID-19 antigen test refers to testing for SARS-CoV-2 antigens, which can be performed using a nasal swab. The specific steps are as follows:
1. Wash your hands thoroughly before starting and clear the nasal passages.
2. Remove the nasal swab, tilt your head backward, and insert the swab 1–1.5 cm into the nostril.
3. Rotate the swab along the inner wall of the nasal cavity 4–5 times, then remove it and place it into the sample extraction tube.
4. Gently rotate the extraction tube, let it stand for 1 minute, then remove the swab, ensuring that the liquid remains inside the tube.
5. Vertically dispense the liquid from the extraction tube into the sample well of the test cartridge, then wait 10–25 minutes to read the result.
To ensure accuracy of the test results, it is recommended to visit a reputable medical facility and perform the test under the guidance of a qualified healthcare professional. If the test result is positive, promptly consult a medical professional for further diagnosis and treatment.
