摘　　要：目的:讨论抗凝新鲜血在血液分析仪室间质量评价以及质量控制中的作用。方法:仪器校准后进行室间、室内质控物的检测,将当日采集制作的抗凝新鲜血分发至各实验室,来完成当天血液分析仪的比对。结果:不同的血液分析仪在各实验室经定值抗凝新鲜血比对校准后,各实验室之间调查抗凝新鲜血各项检测项目的CV显著减少,优秀率由85%提高到95%。结论:抗凝新鲜血的使用,提高各实验室血液分析仪的检测水平,分析结果能统一到同等水平,大大提高检验报告的可靠性和有效性,为临床诊断提高准确的指标。Objective： To study the effect of anti-coagulated fresh blood in external quality assessment and quality control of blood analyzers. Methods： Materials used in external quality assessment and internal quality control was detected after the blood analyzers were calibrated. Anti-coagulated fresh blood was distributed to the laboratories,and the results from the blood analyzers that day were compared with the reference values. Resuits ：After compared with the reference values of fresh blood, the coefficient of variance（CV） of all the indicators in external quality assessment was lower and the excellent rate was improved from 85% to 95 %. Conclusion： The application of anti-coagulated fresh blood improves the detection of blood analyzers in the laboratories. The unified results provides reliable and effective predictors for clinical diagnosis.
