Abstract:

Objective To investigate the status of quality management of new severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) nucleic acid determination laboratories constructed after January 2020 in Zhejiang. Methods A total of 179 SARS-CoV-2 nucleic acid determination laboratories,including 107 new laboratories and 72 laboratories constructed before January 2020(original laboratories),were enrolled randomly to on-site inspection and sample assessment. The statistical analysis of non-conforming terms and assessment results was performed. Results The non-conforming terms of new laboratories were more than original laboratories,and the problems from new laboratories and original laboratories were mainly internal quality control and performance verification. The determination system matching rate of new laboratories was 25.23%,and that of original laboratories was 75.00%. The false negative results of routine testing and rapid testing were all from new laboratories. Conclusions Internal quality control and performance verification are common problems to all the laboratories. It should strengthen the monitoring of weak positive internal quality control cycle threshold(Ct) values and implement proper performance verification protocols. There is a quality gap between new laboratories and original laboratories. It should strengthen the quality management of rapid testing and strengthen personnel skill training.
