摘要
目的评价并比较全自动血小板聚集分析仪LBY-NJ4A与手工血小板聚集分析仪Chrono-log700的主要性能指标。方法评价并比较LBY-NJ4A和Chrono-log700的精密度、通道一致性、参考范围、抗干扰能力以及携带污染率等主要性能,验证两种仪器的相关性。结果两种仪器的精密度、通道一致性、抗干扰能力、参考范围均符合要求,仪器间的相关性好。另外,LBY-NJ4A携带污染率符合标准,Chrono-log700不存在携带污染率,因为其为一次性加样。结论血小板聚集分析仪LBY-NJ4A与Chrono-log700的性能基本符合临床及实验室需要,但LBY-NJ4A抗干扰能力优于Chrono-log700,且自动化程度较高,人工需求较少,因此更有利于实验室大样本量工作的开展。
Objective To evaluate and compare the main performances of automatic light transmission aggregometry(LBY-NJ4A)and manual light transmission aggregometry(Chrono-log700).Methods The main performances of LBY-NJ4A and Chrono-log700 were evaluated,such as precision,channel consistency,reference range,anti-interference ability and carried pollution rate,and the correlation were verified.Results The precision,channel consistency,anti-interference ability and reference range of the two instruments met the requirements,and two instruments were well correlated.The pollution rate carried by LBY-NJ4A met the standard;Chrono-log700 didn′t have any contamination problem because it only needed disposable tips for loading samples.Conclusion Both LBY-NJ4A and Chrono-log700 are basically accorded with clinical and laboratory requirements.LBY-NJ4A has a better anti-interference quality than Chrono-log700.Additionally,it was highly automated and has less labor requirements,so it might be more favorable for laboratories with a large sample size.
