The operation of uncultured infectious substances should be carried out in the second-level biosafety laboratory, and the third-level biosafety laboratory should take personal protection; The operation of inactivated materials should be carried out in the biosafety level II laboratory; Molecular cloning and other operations without pathogenic live viruses can be carried out in biosafety laboratories.
Novel coronavirus Laboratory Biosafety Guidelines (2nd Edition), COVID-19 nucleic acid testing should be carried out in the second-level biosafety laboratory, and the third-level biosafety laboratory should take personal protection.
Please ask local health and wellness committees to take the initiative to dock the biosafety laboratories undertaking nucleic acid detection in COVID-19, do a good job in filing management, strengthen technical guidance and active services, and provide a strong guarantee for improving the nucleic acid detection ability in COVID-19 within their jurisdiction; All localities should guide biosafety laboratories to standardize the operation procedures of COVID-19 sample detection, actively organize and carry out training in experimental operation techniques, personal protection and sample disposal, enhance the biosafety awareness of nucleic acid detection personnel, and ensure the safety of detection personnel and the surrounding environment.
