摘要
目的：评价Beckman Coulter L H750检测系统的性能。方法根据CLSI EP9确定分析仪的真实度，根据CLSI EP5确定分析仪的精密度，通过六西格玛度量方法计算血细胞分析仪各项目的性能并进行评估。结果 L H750白细胞计数（WBC ）的六西格玛水平在5．5～11．1，红细胞计数（RBC）在5．5～9．4，血红蛋白含量（Hb）在6．0～14．6，血小板计数（PLT ）在4．1～10．0，红细胞压积（HCT）的六西格玛值低于了3．0。结论 Beckman Coulter LH750检测系统基本满足六西格玛的质量管理要求， HCT这个项目还需要进行质量改进。六西格玛质量理论可以反映检测过程的性能。
Objective To evaluate the performance of Beckman Coulter LH750 detection system .Methods The truth degree of the analyzer was detected according to the CLSI EP9 and the precision was determined according to the CLSI EP5 analyzer ,the per-formance of various items in the blood cell analyzer was calculated and evaluated by the Six Sigma metrics .Results The Six Sigma level of white blood cell （WBC） count in LH750 was 5 .5-11 .1 ,which of the red blood cell （RBC） count in 5 .5-9 .4 ,which of he-moglobin （Hb） in 6 .0-14 .6 and which of the platelet （PLT） count in 4 .1-10 .0 ,the Six Sigma value of hematocrit （HCT） was lower than 3 .0 .Conclusion The Beckman Coulter LH750 detection system basically meets the requirements of the Six Sigma quali-ty management ,the HCT item also needs to be improved in the quality .The Six Sigma quality theory can reflect the performance of the detection process .
