开展血液病毒核酸集中化检测的效果分析

Analysis on effect of launching blood virus nucleic acid centralized test

目的对血液病毒核酸检测(NAT)集中化在重庆市血液中心开展的效果进行分析。方法 2016年1-6月,对重庆市14家基层血站送往重庆市血液中心的32 137份集中化检测标本的运输、检测、信息系统建设方面等各个环节和关键控制点进行分析。结果在2016年1-6月的32 137份重庆市集中化标本中,对55份标本进行了不同原因的拒收,基层血站标本的NAT单反应性率为5.1‰(164/32 137),同期重庆市血液中心为2.3‰(129/55 859),鉴别检出率基层血站为1.8‰(57/32 137),重庆市血液中心为0.6‰(35/55 859)。结论重庆市血液中心开展病毒核酸集中化检测的效果已逐步显现,基层血站检测实验室与血液中心血筛实验室在检测能力和水平上存在一定的差距,逐步提高集中化检测程度,有助于血液检测效率和血液安全的全面提升。

Objective To annalyze the effect of launching blood virus nucleic acid test（NAT） centralization in Chongqing Municipal Blood Center. Methods The various links and key control points in the aspects of the transportation,detection and information system of 32 137 centralized test specimens submitted from 14 basic level local blood stations in Chongqing counties from January 2016 to June 2016 were analyzed. Results Among 32 137 centralized specimens from January to June 2016,55 specimens were rejected for various reasons, the NAT single reactive rate was 5. 1‰（164/32 137）, which in the Chongqing Municipal Blood Center was 2. 3‰（129/55 859）during the same period. The identification detection rate in the basic level blood station was 1. 8‰（57/ 32 137） , while which in Chongqing Municipal Blood Center was only 0. 6‰（35/55 859）. Conclusion The effects of launching centralized NAT have already gradually emerged in Chongqing Municipal Blood Center. The detection ability and level have differences between the laboratory of basic level blood station and blood screening laboratory of blood center. Gradually increasing the centralized test degree conduces to comprehensive improvement of blood detection efficiency and blood saftey.
