FAQs about antigen self-testing for COVID-19

How to conduct the self-testing?

The COVID-19 antigen self-testing generally uses nasal swab samples. Read and follow the instructions for use. Here is a quick guide.

- Before taking the test, you should wash your hands with water or sanitizer. Read the instructions. Check the expiration date of the kit and whether any part of the kit is missing or damaged. Ensure the environment is suitable for performing the test.

- Blow your nose with tissue before collecting the samples. Take the nasal swab out from its container and avoid touching the tip of the swab with your hands. Insert the swab about 1-1.5 centimeters into one nostril while keeping your head slightly tilted. Rotate the swab inside the wall of the nostril at least four times and no less than 15 seconds. Repeat the same process in the other nostril. People aged 14 or older can collect their own nasal samples. For children aged 2-14, the sample collection should be done by adults.

- Test the swab samples and wait for the results according to instructions.
