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 .
