Abstract
Objective To evaluate the performance of leukocyte differential count with Sysmex XE-2100 automated hematology analyzer. Methods According to H20-A standard approved by National Committee for Clinical Laboratory Standards (NCCLS/CLSI),the performance of leucocyte differential count was evaluated from imprecision, comparability and clinical determination of sensitivity. Results The within-run, short-term and long-term imprecision of the instrument were between 0. 91 %～15. 53%. Compared with the manual microscopy classification, the correlation coefficient( r2 ) of neutrophil, lymphocyte, monocyte,eosinophil and basophil were 0. 956 4,0. 941 8,0. 700 7,0. 931 3 and 0. 811 1 respectively. The clinical determination of sensitivity to finding of abnormal samples were between 50%～100% in 200 clinical cases. Conclusion Sysmex XE-2100 automated hematology analyzer had good clinical determination of sensitivity,low imprecision and fine correlation with manual microscopy classification. It is suitable for the initial screening of clinical diseases.关键词
