In order to further optimize the Novel Coronavirus detection strategy, the Joint Prevention and Control Mechanism Of The State Council recently decided to add antigen detection on the basis of nucleic acid detection as a supplement. The Novel Coronavirus Antigen Detection Application Protocol (Trial) has been formulated and issued.What is an antigen test?Whether virus invades human body, there are three main methods to detect at present: nucleic acid detection, antigen detection and antibody detection.Both are direct detection methods.Antigen tests can be faster and more convenient than nucleic acid tests, but they are less accurate and are generally used in the early stages of infection.Since the outbreak of the epidemic, while recognizing nucleic acid testing as the “gold standard” of novel Coronavirus testing, many countries have promoted antigen testing as an effective supplement.According to the Novel Coronavirus Antigen Detection Application Protocol (Trial), positive antigen results can be used for early triage and rapid management of suspected population, and the selected antigen detection reagents must be approved by the National Drug regulatory authorities.Sources: Xinhua News Agency, People’s Daily, CCTV News
