On March 22, the National Health Commission issued "on the issuance of regional new coronavirus nucleic acid test organization and implementation guidelines (third edition)". The notice is mainly revised for the rapid spread of Omicron mutant strains, highly infectious, insidious transmission and other characteristics, and put forward new new crown nucleic acid rapid test requirements.
1, the new crown nucleic acid rapid test into the situation, to the actual needs to carry out:
Due to the current epidemic situation across the country is not optimistic, everywhere are conducting large-scale rapid testing of new crown nucleic acid, rapid testing of new crown nucleic acid pressure has increased dramatically. In the "Notice", the state clearly requires that the new Nucleic acid rapid test can not be flooded, to be targeted, not to engage in "one size fits all", the need to effectively use the valuable Nucleic acid rapid test resources. The "notice" will be "full new Nucleic acid rapid test" to "regional new Nucleic acid rapid test", the area contains the sealing area, control area, prevention area, can be as small as a building can also be as large as the city-wide.
2, within 24 hours, all must be completed within the new crown nucleic acid rapid test.
In the third edition of the "Notice", clearly adjusted the requirements on the new crown nucleic acid rapid detection time limit: each district city does not distinguish between the size of the population, are in accordance with the city's new crown nucleic acid rapid detection within 24 hours to complete the target matching sampling and new crown nucleic acid rapid detection detection force. If necessary, can be safeguarded through intra-regional collaborative support; if necessary, can apply for national support, in principle, all sampling tasks need to be completed within 6 hours.
3, increase the new crown nucleic acid rapid test sampling method, reduce the new crown nucleic acid rapid test sampling workload.
In the latest version of the Notice, the elimination of 5 mixed 1, an increase of 20 mixed 1, further reducing the workload of sampling personnel. According to the centralized isolation point, the key population to implement a single check; sealing control area solid single check or 1 household 1 tube; control area can be implemented 10 mixed 1;
prevention area and other areas can be implemented 20 mixed 1; single pick single check object multiple rounds of new crown nucleic acid rapid test did not detect a positive, depending on the circumstances of the implementation of 10 mixed 1 mixed.
In addition to the above changes, "Notice" there are very many changes, and none of these changes are not the goal to improve the efficiency of the new crown nucleic acid rapid test and change.
In order to further improve the efficiency of the rapid detection of new crown nucleic acid, the promotion of technological innovation can not wait. Improving the scientific and technological power of the whole process of New Crown Nucleic Acid Rapid Test is the key to promote the speed up.
In the sampling process, we have introduced a cup handling system to reduce manual operation and risk; in the nucleic acid extraction process, we have introduced a dual-module, dual-cleavage extraction system to efficiently extract high-purity nucleic acid; in the amplification analysis process, we have further innovated the technology of real-time fluorescence quantification instrument to achieve precise temperature control and efficient amplification. All of these segments are inseparable from the iteration of technology.
New crown nucleic acid rapid test is a very big change, the introduction of two-step method, one-step method, to further improve the efficiency of rapid detection, so that complex nucleic acid detection experiments tend to POCT development.
