Antigen testing refers to the new coronavirus antigen test, which is generally useful for asymptomatic.
Antigen test is one of the tests to detect Neocoronavirus, infection with Neocoronavirus has a high viral load, even if it is asymptomatic, the antigen test result suggests that it is usually positive, i.e., the antigen test can be detected in asymptomatic infected people.
For antigen test, it is a new crown test proposed after nucleic acid test, but its accuracy is not as high as nucleic acid test. Compared with nucleic acid test, antigen test is faster and easier to operate. Its scope of application is wider, such as quarantine observers, close and sub-closeted persons, and self-testing by residents.
The antigen test can expand the scope of screening in a short period of time, and its detection time is shorter, usually within 30 minutes, so that the virus can be detected in a timely manner, reducing the speed of transmission of the virus, and facilitating the prevention and control of epidemics.
In summary, antigen detection can also detect asymptomatic infected people, and it is recommended to promote the use of antigen detection test strips in large quantities to improve the efficiency of epidemic prevention and control, and to a certain extent, ease the work pressure of prevention and control workers.
