The new version of the nucleic acid testing guidelines is announced. What are the highlights?

On March 22, the National Health and Health Commission announced the "Regional Implementation Guidelines for Novel Coronavirus Nucleic Acid Testing Organizations (Third Edition)", which revised the "full staff" in the second version of the guidelines to "regional", and the size of the region depends on the needs of epidemic prevention and control.
Decision; Emphasizes that nucleic acid testing should be clear and targeted, and cannot be "one size fits all"; clearly promote the monitoring model of "antigen screening, nucleic acid diagnosis".

What are the highlights of the new version of the guide? Why revise and publish the third edition of the guide? Recently, the situation of epidemic prevention and control in China is severe and complicated.
The Omicron variant has the characteristics of fast transmission, strong infectivity, and hidden transmission, which has put forward new and higher requirements for organizations to carry out nucleic acid screening
.
At the same time, in order to summarize the useful experience in promoting nucleic acid screening in the early stage, and guide local governments to solve problems encountered in practice, the third edition of the guidelines was revised and formed
.
What are the major revisions? The main revisions are as follows: First, it emphasizes scientific precision and conducts nucleic acid detection in delineated areas
.
The "full staff" in the second edition of the guide is changed to "area", and the size of the area is determined by the needs of epidemic prevention and control
.
The second is to further clarify the time limit for completion
.
Nucleic acid testing with a defined scope should be completed within 24 hours
.
The third is to add a number of special work classes
.
According to the various links and departments involved in the regional nucleic acid testing, the local government was instructed to set up 9 special classes for data statistics, special classes for collection and inspection matching, and the responsibilities of the special classes were specified
.
The fourth is to provide the basis for measuring the strength of detection
.
The number of sampling personnel and nucleic acid detection capabilities required to complete nucleic acid testing in various regions within 24 hours has been given clear calculation guidance
.
Fifth, simplify the technical requirements for testing
.
Combined with the scope of application of the third edition of the guideline and the actual operation requirements, the existing requirements in technical documents such as the "Work Manual for Novel Coronavirus Nucleic Acid Detection in Medical Institutions (for Trial Implementation)" are not expressed in the text, but are related to the organization, transport, detection, and sampling of samples.
Management requirements such as result disposal are further highlighted and clarified
.
What exactly does "area" refer to? "Area" includes closed area, control area, prevention area
.
The area may be as small as a building or as large as the whole city.
The specific area should be determined by the local epidemic prevention and control headquarters on the basis of scientific research and judgment, and adjusted dynamically according to the actual needs of epidemic prevention and control
.
What are the considerations that emphasize the precise delineation of the detection range? Will there be large-scale full-scale testing in the future? Improving the level of scientific and precise prevention and control is crucial for nucleic acid testing
.
Nucleic acid testing should be targeted and targeted, and there should be no "one size fits all" approach, and valuable nucleic acid testing resources should be effectively utilized
.
Therefore, the third edition of the guide emphasizes the need for accurate and rapid flow investigation and strict community control.
After scientific research and judgment, the scope of testing needs to be delineated
.
The scope of nucleic acid testing is directly related to whether the source of risk is clear, and it is also related to multiple factors, such as whether the traceability of the epidemic is accurate, whether the infected persons are widely distributed, and whether the isolation control measures are implemented
.
Whether large-scale nucleic acid testing of all staff is required depends on scientific research and judgment, and serves the needs of epidemic prevention and control
.
What are the key points worth noting in carrying out regional nucleic acid testing? Carrying out regional nucleic acid testing first requires local party committees and governments to have strong organizational mobilization, deployment and implementation capabilities, and efficient coordination and cooperation between various departments.
Therefore, key requirements are placed on the "organization management" part
.
In addition to organizational management, the local area must fully understand and prepare for nucleic acid detection capabilities in the region, the organization of community sampling, the information management of sampling and testing, the accuracy of sampling operations, and the avoidance of possible cross-infection during sampling.
Matching, the accuracy of nucleic acid testing, and the scientific judgment after each round of testing are all key links that must be paid attention to
.
Will antigen testing be used in the process of testing organizations in various places? In the third edition of the guidelines, antigen testing was mentioned with regard to testing strategies
.
All localities can promote the monitoring mode of "antigen screening and nucleic acid diagnosis" in combination with the relevant requirements of new coronavirus antigen detection, increase antigen detection as a supplementary means of regional nucleic acid detection, and organize implementation after researching and refining the implementation plan
