Analysis on testing ability of blood testing laboratories in domestic blood establishments across China
Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 7
Abstract
Objective To analyze testing ability of blood testing laboratories in domestic blood establishments, and to comprehensively understand the resource allocation, workload and unqualified blood samples. Methods All blood testing laboratories reported the quarterly quality indicator data via their EQA system on the website of National Center for Clinical Laboratories (https: //srv.clinet.cn/qblood/report/add1.aspx). We collected related quality indicators throughout 2020, including resource indicators, number of sample detection, and number (rate) of unqualified samples. All the data were integrated by EQA system. Results 1) Throughout 2020, 324 blood testing laboratories reported that 13 529 778 donations were tested by immunoassays and 13 892 927 donations were tested by nucleic acid testing(NAT). Among them, 253 laboratories reported the data correctly throughout four quarters, and they tested 12 015 407 donations. 2) The number of equipment varied greatly among different laboratories, and a certain equipment was often overloaded in some laboratories. 3) The proportion of domestic ELISA reagents was 100% (322/322), while the proportion of imported NAT reagents was 75.33% (220/300). 4) The positive rate of HBsAg was closely related to geographical locations, as Sichuan (0.86%, 5 895/689 445), Guangdong (0.57%, 5 147/895 929), and Guangxi (0.53%, 3 021/573 216) provinces demonstrated higher positive rates than that of other provincial regions. Conclusions There are many blood stations across China, with great differences in scale and equipment. There are obvious differences in the positive rates of infectious indicators in different regions. Therefore, the laboratory should make horizontal comparison with the laboratories in the same region, to improve the detection quality of the laboratory in time and effectively.
