STA-R Evolution和STA-Compact血凝仪实验性能评价

Performance evaluation of STAGO Compact and STA-R Evolution automatic coagulation analyzers

目的对法国思塔高STA-R Evolution和STA-Compact全自动血凝仪进行性能评价。方法在STA-R Evolution和STA-Compact血凝仪上进行精密度、准确度、生物参考区间验证、线性、携带污染率及比对分析,验证指标为凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、纤维蛋白原(FIB)。结果 2台仪器所验证指标的变异系数均达到CLIA′88的要求。结论2台仪器性能优良,检测结果具有可比性。

Objective To evaluate the performance of STAGO Compact and STA-R Evolution automatic coagulation analyzers. Methods To analyze precision,accuracy,reference interval,linearity,carryover and the comparison test on STAGO Compact and STA-R Evolution automatic coagulation analyzers by determining prothrombin time （PT）,activated partial thromboplastin time （APTT）and fibrinogen（FIB）.Results The CVs of all the tests performance on these two machines could fulfill the requirements of CLIA′88.Conclusion Two machines possess excellent performance,and their results have good comparability.
