目的通过总结分析重庆市血液中心血液筛查实验室自2011~2014年多个项目参加多层级室间质评的结果,达到验证实验室能力和提高检测能力的目的。方法对2011年1月~2014年6月,分别参加的中国国际输血感染预防和控制(CITIC)、原国家卫生部临床检验中心及重庆市CDC病毒研究所等国际、国家、地区3个层次的各项检测质评数据进行统计,分析偏倚原因和提出改进措施。结果参加3个层级的质评活动(共计13个项目的检测),共出现假阳性2次,假阴性4次,2012年、2014年所有结果未出现不符合。结论通过参加多层级的室间质评活动,识别了实验室可能存在的隐患和问题,及时采取了纠正预防措施,观察了纠正措施的实施效果,做到了对实验室检测能力的持续监控,提高了血液筛查能力。
Objective To summarize and analyze the results of multi-level inter-laboratory qualitative assessment of multiple blood test centers in Chongqing Blood Center Blood Screening Laboratory from 2011 to 2014 to verify the laboratory capabilities and improve the detection ability. Methods From January 2011 to June 2014, three international, national and regional levels including China CITIC (International Center for Prevention and Control of Blood Transfusion Infection), the Clinical Laboratory of the Ministry of Health, and the CDC Institute of Chongqing The quality assessment data of various tests are statistically analyzed to analyze the causes of bias and propose improvement measures. Results Participate in three levels of quality assessment activities (a total of 13 items of testing), a total of two false positives, false negatives four times, 2012, 2014 all results did not appear non-compliance. Conclusions By participating in the multi-level inter-laboratory quality assessment activities, the potential hazards and problems in the laboratory can be identified, the corrective and preventive measures can be timely taken and the effectiveness of the corrective measures observed. The continuous monitoring and improvement of laboratory testing capability has been achieved Blood screening capabilities.
