采用线性质控品评价Coulter LH780血液分析仪的线性

摘要

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)×109/L、(0.00～7.92)×1012/L、0.3～236.0 g/L 以及(0.3～2511.0)×109/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.
