Do a good job of the "gatekeeper" of the new crown nucleic acid detection -the story behind Lanzhou nucleic acid detection

Gansu Daily Gansu Daily Newspaper Group All Media Interview Reporting Group reporter Xue Weimin Su Jiaying Zhang Yanru Ouyang Haijie Li Jing

Tens of thousands of nucleic acid sampling personnel fought at the streets and lanes of Lanzhou City and the residential courtyard. At the peak, the single -day nuclear acid sampling volume exceeded 3.4 million people ... Since the epidemic in this round, Lanzhou has conducted multiple large -scale regional nucleic acid tests. After nucleic acid samples, how to quickly and efficiently identify positive samples and control the source of communication as soon as possible, it becomes the top priority.

In the first time of the nucleic acid samples to the nucleic acid testing laboratory, the "virus hunter" scrambled to "poison".

The indoor scene of nucleic acid detection laboratory.

Whether it is "10 mixed 1", "5 mixed 1" or "single collection tube", after the nucleic acid sample arrives in the laboratory, a series of strict processes such as signing, enrollment, extraction, amplification, observation, etc. Only only The test report feedback to the citizens of the inspection.

"The guarantee of the quality of nucleic acid detection should start with the collection of samples." Wei Lianhua, director of the Gansu Provincial Clinical Inspection Center, told reporters that after the sample collection is completed, a special specimen transit box will be used to transfer. Whether the test tube is tightened, whether the barcode is clear, whether the sample box is disinfected, etc., and then the specimen transit box is sent to the test point by a special medical personnel.

The reporter followed the transfer car to the detection point. The specimen receiving group and the test personnel must first review the barcode and check the information. After ensuring that the specimen meets the testing requirements, the nucleic acid in the operating specification is strictly obtained. PCR detection methods put the original nucleic acid large, read the fluorescent curve through the instrument, and observe whether there is a nucleic acid sequence corresponding to the new coronal virus.

The nucleic acid testing laboratory staff is working nervously and orderly.

"Nucleic acid detection technology is an accurate but extremely sensitive molecular detection technology. The correct collection of specimens, the application scenarios of nucleic acid detection technology, the extraction of nucleic acid detection technology, the expansion of genes, the review of the test results, and the positive judgment. Related quality control should be done well in the aspects of false positive and false negatives, the review and reporting of data, and biological safety protection. "Wei Lianhua said.

After this round of epidemic, 53 nucleic acid testing laboratories in Lanzhou were put into the nucleic acid testing work for the first time. In this regard, the relevant departments of Lanzhou City have built 2 hard gas membrane laboratories and dispatched 16 mobile detection square cabins to meet the city's nucleic acid detection needs and improve nucleic acid detection capabilities.

According to statistics, the province has recently dispatched 6,455 sampling personnel, 563 nucleic acid testing personnel, 90 expansion instruments, 40 extracters, and actively strive for third -party testing capabilities in other provinces. The ability to quickly increase to 794,000 tubes.

Zhao Jing, director of the Gansu Working Group of the Gansu Working Group of the State Council ’s joint defense and control mechanism and the director of the Medical Management Service Guidance Center of the National Health and Health Commission, introduced that at present, nucleic acid testing is the most effective means of discovering the new crown virus infection. Cut off the virus transmission chain.

"Especially in the current situation, repeated testing is repeated, which can timely lock the risk areas and key groups in time. As soon as possible, the source of infection is found, the pathway of infection is blocked, and the susceptible people are protected." Zhao Jing said.

In order to efficiently respond to the aggregate epidemic of emergencies, the leadership group of the Provincial Federation of Defense and Control has previously decomposed regional nucleic acid detection tasks into 9 steps such as preparation, starting conditions, and detection frequency. , Matching inspection and matching, sample transfer, etc. 9 regional nucleic acid testing classes, optimize the strategy of nucleic acid detection and antigen detection, make full use of the detection resources, improve the detection efficiency, and complete the regional nucleic acid sample of regional nucleic acids in 6 hours, 24 hours of 24 hours The completion of the regional testing task has laid the foundation.

After this round of epidemic, the Provincial Health and Health Commission further strengthened the management of sections of mining, delivery, inspection, and newspapers, and guided the detection institutions to select the site selection, venue layout, sampling process, information system, environment, delivery and testing time limit, etc. Regularly regulate, keep an eye on key links such as information collection, on -site standardized sampling, specimen inspection, medical waste disposal, laboratory biological safety protection and other key links, and promote the rapid improvement of nucleic acid detection efficiency and detection quality synchronization.

Faced with the current situation of the epidemic situation in Linxia and Gannan Prefecture, our province according to the nearest strategy, from Longnan City to schedule 10,000 daily testing square cabin laboratories. Provincial hospitals have dispatched nearly a thousand nucleic acid samples and test personnel. At present, related cities such as Lanzhou, Gannan Prefecture, Linxia Prefecture and other related cities and states are conducting corresponding regional nucleic acid testing in an orderly manner.
