What is the principle of COVID-19 self-test box?
The principle of COVID-19 self-test box is antigen detection. Antigen detection is the direct detection of specific protein (antigen) in virus, which can quickly detect whether there is virus in human body during acute infection period and provide direct evidence of virus infection. The operation is simple and quick, and it can be used for early triage and rapid management of suspected population.
According to China's "COVID-19 Antigen Detection Application Scheme (Trial)" published in March, 2022 1 1, in order to further optimize 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 and 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 generally accurate, but its accuracy may be lower than that of nucleic acid detection.
The sensitivity and accuracy of novel coronavirus nucleic acid detection kit from 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 is of great value. Antigen testing has been adopted in Hong Kong's anti-epidemic, and organizations involved in anti-epidemic also recognize this testing method. Through antigen testing, we can directly announce whether COVID-19 is infected or not, and then take a series of measures.
COVID-19 self-test box is a newly-launched test product. It can detect whether people are infected with COVID-19, 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?
