摘　　要：目的:评价ABX MICROS CRP血细胞分析仪的全血细胞计数(CBC)和白细胞分群(DC)的性能。方法:按照有关文件规定对该仪器CBC的性能指标进行评价,并与人工分类进行比较。结果:该仪器CBC的精密度、携带污染率和总重复性均符合要求;在正常及常见的病理范围线性良好;与XE-2100的结果比较,相关性好(r>0.99)。DC:中性粒细胞(GRAN)、淋巴细胞(LYM)和中间细胞(MID)的重复性好;WBC比例及形态正常的样本,仪器与人工DC的结果比较,GRAN和LYM相关性较好(r>0.98);较高比例的幼稚细胞可在WBC直方图显示。结论:该仪器检测的结果准确、可靠,主要性能指标符合实验要求;对怀疑分类异常的标本,仪器DC结果必须经显微镜复核后才能报告。Objective To evaluate the performance of ABX MICROS CRP hematology analyzer. Methods The indexes including precision, total reproducibility, carry-over, linearity （dilution effect） and comparability were examined according to published evaluation standard. At the same time, the differential count （DC） produced by the analyzer was compared with that produced by manual methods. Resuslts Precision, carryover and total reproducibility in counting of leucocytes, erythrocyte, platelets and examming of hemoglobin on the analyzer were showed in the prescriptive range. There were also good linearity in normal and pathological range and the results correlated well with those obtained on Sysmex XE-2100 （ r〉 0. 99）. DC ： reproducibility was good for granulocytes, middle cell and lymphocytes. Comparison of the results by instrument with manual for normal samples in cellular ratio and morphology, the correlation was good for granulocytes and lymphocytes （r〉0.98）; immature cells would display in the WBC histogram when in higher proportion. Conclusions The analyzer can be used to test blood cell parameters accurately and reliably. Its main performance indices accorded with the experimental requirements; The results were credible. It is necessary to checked with microscopy for DC before reported.
