Recently, due to the relationship between the epidemic, many regions have launched several rounds of large-scale nucleic acid testing in accordance with the form of epidemic prevention and control, in order to effectively control the risk of epidemic transmission and effectively protect the life safety and physical health of the broad masses of the people.
A box of nucleic acid specimens after being collected, transferred to the medical units or third-party testing agencies and other PCR laboratories, one by one scanning code signing, after sorting, verification, numbering and other links, and finally the specimens are arranged in an orderly manner for testing, in the process of specimen scanning and receiving, sometimes you will find specimens with missing or incomplete information.
How do we address these issues? Is it like a regular blood test specimen, rejected according to the unqualified specimen? Like some testing agencies, can not scan the code directly rejected? If the relevant specimen to be tested is positive and refuses to be accepted, is it not another form of missed test?! Below I will exchange and discuss the treatment plan of my own department and your test colleagues, we will first conduct specimen testing of the new crown nucleic acid specimens with missing or incomplete information, and trace the source of the test results at the same time.
Specific implementation steps:
First, the specimen signing (specimen receiving personnel with 75% alcohol disinfection of the transfer box, take the dirt channel, the transmission window to the PCR laboratory specimen preparation area, open the transfer box in the biological safety cabinet, 75% alcohol disinfection at the moment of opening the box, take out the specimen for inventory and inspection, check and confirm with the inspection personnel. ）
