China News Service, January 18th. The website of the National Health and Medical Commission released on the 17th the interpretation of the "Technical Specifications for 20-in-1 Mixed Collection and Detection of New Coronavirus Nucleic Acids", saying that in order to further improve the nucleic acid detection of new coronaviruses and gain valuable time for epidemic prevention and control, On the basis of the current 5-in-1 and 10-in-1 mixed detection, the Medical Rescue Team of the Joint Prevention and Control Mechanism of the State Council has actively organized professional institutions and experts to demonstrate and research and propose technical methods to further improve the efficiency of nucleic acid detection.

After carrying out the verification of clinical real samples, on the basis of ensuring the quality of nucleic acid detection, it was decided to steadily implement the 20-in-1 mixed-sampling detection technology, and organized the formulation of the "Technical Specification for 20-in-1 Mixed Collection Detection of New Coronavirus Nucleic Acid" (hereinafter referred to as the "Specification"). ).

  The 20-in-1 mixed-collection detection can greatly improve the detection efficiency, and is more suitable for large-scale population nucleic acid screening.

Compared with the 10-in-1 mixed sampling detection technology, the adjustment is mainly made in the sampling tube.

  The "Specification" is divided into 10 parts, mainly including: sample collection consumables specifications, collection site requirements, collection process, specimen submission, laboratory reception, specimen testing and quality control, test result processing, post-test sample processing, technicians Basic requirements, biosafety protection, etc.
