摘要
目的:评价XS-800i血细胞分析仪全血细胞计数(CBC)和白细胞分类(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)。白细胞分类:中性粒细胞(Neut)、淋巴细胞(Lym)、单核细胞(Mon)、嗜酸性粒细胞(Eos)和嗜碱性中粒细胞(Baso)的重复性好;WBC形态正常的样本,仪器与人工显微镜的结果比较,Neut、Lym和Eos相关性较好(r值分别为0.9816、0.9795、0.9629);Mon次之(r值为0.8283),Baso的相关性欠佳(r值为0.5874)。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WBC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 Sysmex XS-800i hematology analyzer on CBC and DC. Methods The indexes including precision, total reproducibility, carry-over, linearity （dilution effect） and comparability were examined according to the relevant standard and compares with manual classification. Results The CBC of precision, carry-over rate and total reproducibility was meet the request. The instrument was better than XE-2100 in correlation （r〉0.99）. Leukocyte differential count： Neut, Lym, Mon, Eos and Baso has good reproducibility. Among the comparisons of normal samples and microscopic effect, the Neut, Lym and Eos first place（r=0.9816, 0.9795 and 0.9629）, the Mort second（r=0.828 3）, the Baso comes last （r=0.587 4）. Conclusion The analyzer can be used to test blood cell parameters accurately and reliably. Its main performance index meets the experimental requirements. It must be approved by the microscope for abnormal example of WBC before report.[Chinese Medical Equipment Joumal, 2008,29 （12） ： 86-88]
