摘要
目的:评价Sysmex-CA7000全自动凝血仪的性能。方法:选择活化部分凝血活酶时间(APTT)、凝血酶时间(TT)、纤维蛋白原(FIB)、凝血酶原时间(PT)四个常用凝血检测项目分别从仪器检测准确性、精密度,抗干扰性及参考范围几方面对SysmexCA7000凝血仪进行性能验证。结果:四个项目准确性验证结果均符合厂家要求(CV%<5%),但低值样本PT(CV3.13%)和TT(CV3.36%)准确性不及其他几个项目;批内和批间精密度检测均满足厂家要求,且除PT外其余三个项目远低于厂家要求CV%;参考范围验证和抗干扰能力结果显示四个检测项目均较理想。结论:Sysmex CA7000凝血仪具有检测准确性好、精密度高、检测范围宽、抗干扰能力强等特点,值得临床推广应用。
Objective： To evaluate the performance of CA-7000 automatic coagulometer system. Methods： Items of prothrombin time （PT）, activatedpartial thromboplastintime （APTT）, thrombin time （TT） Fibrinogen （Fg）, were included to evaluate the CA-7000 automatic coagulometer system of accuracy, precision, interference and reference range. Results： The validate result of accuracy of the four indexes were in line with the requirements of manufacturers （CV%〈5%）, but accuracy of low value samples PT （CV3.13%） and TT （CV3.36%） were lower than other indexes; Detection of precision between within batch and inter batch both met the requirements of manufacturers, and the three indexes, except PT, were far below the requirements of manufacturers CV%; Reference range and ability of anti disturbance were ideal according to the four indexes. Conelusion： CA-1700 Coagulation analyzer has good characteristics of detection accuracy, high precision, wide detection range, strong anti-interference ability, it＇s worthy of clinical application.
