Hefei Nucleic Acid Testing Laboratory

Read Time:2 Minute, 15 Second

On the evening of February 9, the Hefei Baohe District Disease Control Center sent a batch of test specimens to the Hefei Qianmai Medical Test Laboratory in Baohe Economic Development Zone for nucleic acid detection and screening. . The laboratory was previously verified by the Anhui Provincial Clinical Inspection Center and confirmed by the Office of the Provincial Epidemic Prevention and Emergency Comprehensive Command. It became the first batch of third-party testing institutions in Anhui Province that can carry out the detection of new-type coronavirus nucleic acids.

It is understood that due to the high level of biological safety and the many testing procedures, nucleic acid testing laboratories (PCR laboratories) have strict requirements on airflow control and negative pressure environment. In this laboratory, the internal partitioning is strict, and the aseptic operations do not interfere with each other. The disinfection and protection of the inspectors entering the laboratory is strict and orderly. Part of the processing is completed by the inspectors wearing a full set of protective equipment with the help of an isolation cabinet to ensure the safety of the test

“Generally speaking, when we receive the test specimen in a closed container, we will send it to the laboratory through a special channel. This process is absolutely to prevent leakage.” According to the person in charge of the laboratory, after the specimen enters the PCR laboratory, it will be put into a device together with the sealed container for inactivation. “At the end of the inactivation, the inspectors take it out of the sealed tank , run it on the machine for centrifugation, and then carry out nucleic acid extraction after centrifugation. At the end of the nucleic acid extraction, the amplification apparatus is used to analyze the virus in the sample, and the final result obtained. ”

The official said frankly that in the laboratory, inspectors were “racing” every day with samples of possible viruses. “Each round of sample operation is completed by 3-5 laboratory personnels. The epidemic situation is fierce, requiring us to take a professional and rigorous attitude and responsibility for each specimen and step of inspection to ensure the accuracy of the test results. To ensure that the testing process has both speed and quality, and to gain more valuable time to fight the epidemic. “

It is reported that the laboratory has received new coronavirus specimens from disease control centers in multiple urban areas in Hefei, Anqing and Fuyang . It takes about 6 hours to test a single sample from receiving it to the final test result. At the same time, according to laboratory testing capabilities, about 1,000 nucleic acid samples can be tested every day.
