A Must-Read Before Covid-19 Antigen Self-Test!

Doing antigen self-test is like preparing ingredients before cooking. Only when you are fully prepared can the results be reliable! According to official guidelines and doctor's advice, pay attention to these points before testing:

1. Environmental and personal preparation

‌Hand washing and disinfection‌: Clean your hands thoroughly with soap or hand sanitizer for more than 20 seconds before testing to avoid contaminating the sample‌.

‌Read the instructions‌: The operation of different brands of test kits may be different. First, carefully read the steps and precautions‌.

‌Check the reagents‌: Confirm that the reagents are within the shelf life, the packaging is not damaged, and the accessories such as nasal swabs and sample tubes are complete‌.

2. Test environment requirements

‌Temperature and humidity‌: It is best to operate at room temperature of 14-30℃. Too cold, too hot or too humid may affect the results‌.

‌Ventilation and cleaning‌: Choose a clean and ventilated place to avoid testing in dusty or humid places‌.

3. Details before sampling

‌Nasal cleaning‌: Blow your nose with a tissue first, but don't wipe your nasal cavity with disinfectant‌.

‌Avoid interference‌: Do not smoke, drink or chew gum 30 minutes before sampling, which may affect the results‌.

‌Posture preparation‌: When sampling, tilt your head back and open your mouth like when doing nucleic acid‌.

4. Other precautions

‌Best time for testing‌: Test within 3-7 days after the onset of symptoms, when the virus load is high and the results are more accurate‌.

‌Backup mask‌: Sampling may stimulate sneezing, so it is recommended to bring an extra mask as a backup‌.

Make these preparations, and your antigen self-test will go more smoothly! If the test result is positive, remember to report it in time and do nucleic acid confirmation‌.
