采用线性质控品评价Coulter LH780血液分析仪的线性

Evaluation of the linearity of Coulter hematology analyzer LH 780

目的:对Coulter LH 780全自动血液分析仪做线性评价。方法:采用原装配套试剂、校准品和室内质控品,以原装线性质控品为样本评价白细胞计数(WBC)、红细胞计数(RBC)、血红蛋白浓度(Hgb)以及血小板浓度(Plt)4项参数的线性范围。结果:4项参数的检测结果均呈良好线性关系,WBC、RBC、Hgb及Plt的线性范围分别为(0.03~363.5)×10~9/L、(0.00~7.92)×10^(12)/L、0.3~236.0 g/L以及(0.3~2511.0)×10~9/L。结论:LH 780血液分析仪的线性范围宽泛,能满足临床实验室的检测要求。

Objective：To evaluate the linearity of Coulter automated hematology analyzer LH 780. Methods：The linearity control used to be samples, the linear range of WBC, RBC, Hgb, Plt were evaluated with Coulter original reagents, calibrator and control. Results：The test results of the four parameters showed good linear relationship. The linear range of WBC, RBC, Hgb, Plt were （0.03~363.5）×109 /L, （0.00~7.92）×1012/L, 0.3~236.0 g/L and （0.3~2511.0）×109/L, respectively. Conclusion：For Coulter hematology analyzer LH 780, there is a wide linearity that can meet the demands of clinical laboratories.
