Xinjiang ensures the accuracy and standardization of nucleic acid sampling from five aspects

Tianshan News (Reporter Su Luping reported) On the evening of September 27, the Press Office of the People's Government of the Autonomous Region held a press conference on epidemic prevention and control. At the meeting, Hu Zhichun, a member of the Party Group of the Health and Health Committee of the Autonomous Region, answered questions from reporters.

Sampling is one of the important parts of nucleic acid detection. The degree of specifications of sampling operations directly related to the accuracy and reliability of the detection results. At present, the most commonly used nucleic acid collection method is nasopharyngeal swab and oral pharyngeal swab. Sample personnel wipe back and forth slightly on both sides, and then wipe the mucosal epithelium cells up and down on the posterior wall of the pharynx.

This has certain requirements for the operation technology of sampling personnel. Therefore, in accordance with the relevant documents of the State Council's joint prevention and control mechanism, the staff engaged in the collection of new crown virus nucleic acid testing specimens shall be trained by the health and health department, proficient You can get in the post.

In order to ensure the accuracy and normality of nucleic acid sampling, the following aspects should be paid attention to:

First, the qualifications of sampling personnel are strictly reviewed. The district has always strictly strictly manage nucleic acid sampling personnel. In accordance with the principle of "not training or not, training is not qualified and not qualified", to ensure the operation and behavior of the sampling personnel. The health and health department standardized training, proficient in the collection method of nasopharyngeal and oral pharyngeal swabs and personal protection skills.

The second is the sampling process operation, the sampling table is reasonably equipped with personnel, strictly executed hand hygiene when collecting specimens, disinfected one by hand, strictly infected and controlled during the sampling process. , Strictly implement the requirements of a safe distance interval to prevent cross -infection.

The third is strict specimen preservation and transfer, reasonably determine the transfer time and frequency, place the collected specimens in a special sample transit box with ice row, and collect and transfer it every half an hour to 2 hours, and transfer to the experiment without more than 3 hours. The room is tested to achieve strict biological safety and specimen transshipment training assessment through strict biological safety and specimen transshipment training.

The fourth is to strengthen the quality control of nucleic acid sampling. The whole region has continuously strengthened the control of nucleic acid sampling quality. Each nucleic acid testing agency analyzes the internal reference data of the testing reagent to monitor whether the sample swab is collected to the epithelial cells, and timely feedback the sampling point in the jurisdiction to supervise the relevant information in time to urge Improve sampling quality.

Fifth, an unannounced inspection of the organizational sampling session. The district has set up a nucleic acid sampling unannounced visitor inspection expert group to conduct unannounced visits inspections on the sampling point from time to time. Inspection of medical waste disposal, and feedback the problems found to the territorial epidemic prevention and control headquarters, urge the implementation of rectification, and continuously improve the quality of nucleic acid samples.
