目的对17家采供血机构血液成分细菌检测室间质评结果分析。方法 2014年度共开展了2次细菌检测室间质评活动,每次质评包括6个阳性标本和4个阴性标本,采用冻干后常温运输的方式发放。参评实验室通过在线信息系统OASYS完成质评结果的上报。结果 2次质评活动均有17家采供血机构实验室参加。第1次室间质评阳性标本的检测符合率为94.1%(16/17);第2次室间质评,阳性标本的检测符合率为100%(17/17),阴性标本的检测符合率为76.5%(13/17)。结论通过参加细菌室间质评,可提高实验室检测水平,也可将其作为工作人员日常考核的一部分。
Objective To analyze the results of laboratory tests on blood components of 17 blood collection and delivery agencies. Methods In 2014, a total of 2 laboratory tests for bacterial detection were carried out. Each quality assessment included 6 positive samples and 4 negative samples, and was distributed by means of normal temperature after lyophilization. Participating laboratories through the online information system OASYS to complete the quality assessment results reported. Results of the second quality evaluation activities are 17 blood supply agencies to participate in laboratories. In the second interplastology assessment, the positive rate was 100% (17/17) in the positive detection of the first positive interlaboratory test, and the negative detection was in line with the negative rate The rate was 76.5% (13/17). Conclusions Laboratory bacteriological assessment can be enhanced by participation in bacterial inter-laboratory quality assessment and can also be used as part of daily staff assessment.
