摘　　要：目的评价BC-5000五分类血细胞分析仪(BC-5000)的主要性能。方法对BC-5000的本底及空白值、携带污染率、精密度、准确度、正确度、线性范围及其检测结果与参比仪器(XE-2100)、人工分类的可比性进行评价。结果 BC-5000各参数的本底及空白值均合格,携带污染率均小于1%。所有参数均具有较好的批内和批间精密度,准确度及正确度验证合格。WBC、RBC、HGB、PLT具有良好的线性(r>0.990)。与XE-2100及人工分类结果进行对比,只有嗜碱性粒细胞百分比(Bas%)的相关性略差(r=0.744,P>0.05)。结论 BC-5000具有良好的性能,是一款理想的小型五分类血细胞分析仪。Objective To evaluate the performance of BC-5000 five categories hematology analyzer（BC-5000）.Methods The background and blank values,carryover rate,precision,accuracy,trueness,and linear range were evaluated,as well as the comparability of its results with reference instrument（XE-2100）detection and artificial classification of leukocytes.Results The background and blank values were both qualified.The carryover rates of all the detection items were less than 1%.The intra-and interprecision of all the detection items were good,and the accuracy and trueness were verified eligibility.The linearity of WBC,RBC,HGB,and PLT were good（r〉0.990）.Comparing with XE-2100 and artificial classification,Bas% was the only one item with poor correlation coefficient（r=0.744,P〉0.05）.Conclusion BC-5000 has good performance in hematology detection,and it is an ideal small five categories hematology analyzer.
