IL ACL 7000型全自动血凝分析系统的性能评价

目的对已在实验室使用两年的ILACL7000全自动血凝分析仪进行全面性能评价。方法运用国际血液学标准化委员会（ICSH）公布的专业技术方案，在仪器上检测新鲜血浆、混合血浆和定值参比血浆凝血酶原时间（Prothrombin Time，PT）、活化部分凝血活酶时间（Activated Partial Thromboplastin Time，APTT）、凝血酶时间（Thrombin Time，TT）和纤维蛋白原（Fibrinogen，Fib）等项目，进行精密度、准确度、线性范围和携带污染率等评价。结果PT（s）、APTT（s）、TT（s）和Fib（g／L）的批内精密度为0．69％～2．18％，批间精密度为0．86％～3．43％，相对偏倚（Bias％）为1．6％～3．0％，平均回收率为98．1％，携带污染率为0．4％～1．0％。结论ILACL7000血凝分析仪在使用两年后仍具有较高的精密度和准确度，也具有良好的线性范围，完全可为临床提供准确的检测结果。

Performance Evaluation of IL ACL 7000 Coagulation Analyzer System

Objective To conduct a comprehensive performance evaluation of IL ACL 7000 Fully Automated Coagulation Analyzer used for two years in the laboratory. Methods With professional and technical programs released by the International Council for Standardization in Haematology （ICSH）, fresh plasma, mixed plasma, plasma prothrombin time （PT）, activated partial thromboplastin time （APTT）, thrombin time （TT）, fibrinogen （Fib） and other projects were detected in the apparatus to evaluate the precision, accuracy, linear range and carrying stain rate, etc. Results The intra-inter-assay precisions ofPT （s）, APTT （s）, TT （s） and Fib （g / L） were 0.69% - 2.18%, 0. 86% - 3.43% respectively, relative bias （Bias%） was 1.6% - 3.0%, the average recovery was 98.1%, carrying stain rate was 0.4% - 1.0%. Conclusions IL ACL 7000 Coagulation Analyzer used for two years still has high precision and accuracy, and also has a good linear range, which may fully provide accurate detection results for clinic.
