Today (March 15) afternoon, the State Council Joint Prevention and Control Mechanism held a press conference. At the meeting, Li Jinming, deputy director of the National Health Commission’s Clinical Laboratory Center, introduced that if antigen detection is compared with nucleic acid detection, its specificity is different.
The specificity of antigen detection can reach 99%, but the specificity of nucleic acid detection method is 100%, that is, the nucleic acid detection method has no false positives. Therefore, nucleic acid testing has always been the basis for determining new crown infection, and it is the “gold standard”. Therefore, antigen detection cannot replace nucleic acid detection. When the antigen test is positive, the nucleic acid test must be used for confirmation. However, if the nucleic acid test is positive, regardless of whether the antigen test is negative or positive, the subject must be treated as a new crown infection or a confirmed patient to take measures.
