5 things to avoid when using Covid-19 rapid test kit
(Baonghean.vn) - Below are 5 things experts advise to avoid if you want to get the most accurate results from using the Covid-19 rapid test kit.
Store the test kit at the wrong temperature
Covid-19 rapid test kits should be stored at 2 to 30 degrees Celsius for stability. Storing at high temperatures can cause the proteins in the test kit to denature. Do not freeze the kit as this can also damage the components of the SARS-CoV-2 antigen test kit.
Use the tool kit directly from the refrigerator
Buffer solutions (kit components) will not work well at cold temperatures. The test kit should be removed from cold storage for approximately 30 minutes before use.

Always check the expiry date on the kit.Covid-19 rapid testbefore use. Tests with expired test kits may contain inactive or denatured buffer solutions, causing erroneous results.
Covid-19 rapid test kit opened too soon
Do not open the test kit components until you are ready to start. Testing with the test kit components opened too early can result in a false positive result (you can test positive without actually having Covid).
Performing rapid testing too soon
According to a study, experts have shown that rapid Covid-19 test kits cannot detect SARS-CoV-2 (the virus that causes Covid-19) after two days of exposure. It takes an average of three days or more to detect a positive result when using rapid Covid-19 test kits.
