ACL-TOP700全自动血凝分析仪性能验证与评价

摘要

Objective To verify the performances and evaluate the reliability of ACL-TOP700 automatic coagulation analyzer. Methods The analyzer had its precision, accuracy, carryover, linear range, reference interval and etc analyzed and verified according to the requirements of Clinical and Laboratory Standards Institute (CLSI) for PT, APTT, FIB, TT, DDHS, FDP and etc. Results The within-and between-array precision was both lower than 5%, which met the requirements of medical laboratory ISO 15189 requirements;the accuracy satisfied the requirements of external quality assessment by Beijing Center for Clinical Laboratory; linear analysis found high linearity (r≥0.975 or r2>0.95) in FIB, DDHS; the carryovers of FIB and DDHS were-0.34%and-0.10%respectively;more than 90%test results were restrained in the reference interval according to normal distribution principle. Conclusion ACL-TOP700 automatic coagulation analyzer has high performances and reliable results, and thus is worthy promoting clinically.%目的:对ACL-TOP700全自动血凝分析仪的性能进行验证,评价其检测的可靠性.方法:根据美国临床和实验室标准化协会(Clinical and Laboratory Standards Institute,CLSI)要求,对该分析仪检测凝血酶原时间(PT)、活化部分凝血酶时间(APTT)、纤维蛋白原(FIB)、凝血酶时间(TT)、D-二聚体(DDHS)、纤维蛋白降解产物(FDP)等项目的精密度、准确度、携带污染率、线性范围以及参考区间等进行分析验证.结果:该分析仪检测6个项目批内、批间精密度均小于5%,符合医学实验室ISO 15189血液专业要求;准确度达到北京市临检中心的室间质评要求;以FIB、DDHS为代表的线性分析中r≥0.975或r2>0.95,线性良好;FIB及DDHS携带污染率分别为-0.34%、-0.10%;按正态分布原则,≥90%的个体检测结果在参考区间内.结论:ACL-TOP700全自动血凝分析仪多项综合性能验证指标合格,能够保证检测结果的正确可靠,可以投入临床使用.
