Is COVID-19 self-test box accurate?

COVID-19 self-test box is a newly-launched test product. It can detect whether people are infected with COVID-19 virus, which is very helpful for epidemic prevention and control. Many people will use the COVID-19 self-test box. What is the principle of COVID-19 self-test box? Is COVID-19 self-test box accurate?

What is the principle of COVID-19 self-test box?

The principle of COVID-19 self-test box is antigen detection. Antigen detection is to directly detect the specific protein (antigen) in the virus, which can quickly detect whether there is virus in the human body during acute infection, provide direct evidence of virus infection, and is simple and fast to operate, and can be used for early triage and rapid management of suspected people.

According to China's "COVID-19 Antigen Detection Application Scheme (Trial)" published on March 6, 2022 1 1, in order to further optimize the COVID-19 detection strategy and meet the needs of epidemic prevention and control, the comprehensive group of the State Council Joint Prevention and Control Mechanism decided to promote the monitoring mode of "antigen screening+nucleic acid diagnosis" and add antigen detection as a supplement on the basis of nucleic acid detection.

Is COVID-19 self-test box accurate?

As long as the COVID-19 self-test box is used correctly, the test results are usually accurate, but its accuracy may be lower than that of nucleic acid detection.

The sensitivity and accuracy of novel coronavirus nucleic acid detection kit produced by different manufacturers are different, so the accuracy of COVID-19 detection kit is also different. However, compared with nucleic acid detection, the accuracy of COVID-19 test kit is slightly lower.

Everything has two sides. The sensitivity of antigen detection is slightly lower because it is not amplified, but once it is positive, it will be of great value. Antigen testing has always been used in Hong Kong's anti-epidemic, and organizations involved in anti-epidemic also recognize this testing method. Through antigen testing, it can directly announce whether COVID-19 is infected, and then take a series of measures.
