应用NCCLS指南文件Ep5-A对新仪器精密度性能的评价

Evaluate the Degree of Precision of the New Apparatus by Applying NCCLS Standards Ep5-A

目的 对新购进仪器精密度性能进行评价。方法 按照NCCLS指南文件Ep5 A的要求进行。 结果 除Cr高浓度异常值总变异系数为 2 6 3%外 ,项目ALT ,UA ,CHO的总变异系数均大于 5 %。结论 仪器精密度性能不够理想。

Objective To evaluate the degree of precision of the new apparatus. Methods All tests were done according to NCCLS standard Ep5-A. Results The general CV of ALT, UA, CHO and Cr are all above 5%. Except that the general CV of the high unusual Cr was 2.63%. Conclusion The degree of precision of the new apparatus is not satisfactory.
