In response to the epidemic, another enterprise, Da An Gene Co., Ltd., under Sun Yat-sen University, quickly launched targeted research and development and announced the development of a novel coronavirus pneumonia nucleic acid detection kit on January 13. Da An Gene Co., Ltd became one of the first two manufacturers nationwide to develop and
release such kits, and the first in Guangdong, obtaining relevant certificates on January 28. The kits are now being used widely at medical institutions of all levels.
When questioned about the accuracy of nucleic acid detection, Zhang Bin, deputy general manager of Da An Gene Co., Ltd, told GRTradio:
"In general, because nucleic acid detection technology, which is what we refer to as fluorescent PCR technology, is very technical, the screening process requires the collection of samples, the processing of samples, and the addition of nucleic acid into testing machines. The entire process needs to be standardized to be effective. A problem at any stage would cause results to be less accurate”
Da An Gene Co., Ltd opened its normally sealed-off Yunkang Lab to GRTradio reporters to display how nucleic acid testing works. Samples retrieved from hospitals are tested daily in what are referred to as "specimen pre-processing" and "specimen processing" rooms.
For safety, when the sorted samples are sent to the 'specimen processing room' on the second floor, they are transported by a special elevator. They are isolated from workers who move upstairs. After preliminary work is conducted, results can be obtained after 3.5 hours in the specimen processing room."
Staff at the laboratory are working on a two-shift basis to make sure the lab continues to operate 24 hours a day.
