Sysmex XS-800i全自动血细胞分析仪性能评价

目的评价Sysmex XS-800i全自动血细胞分析仪的性能。方法对Sysmex XS-800i的准确性、批内及批间精密度、携带污染率、稀释效果、总重复性、白细胞分类检测的重复性进行测定,并取20例健康体检和病人标本同时用SysmexXS-800i和Sysmex XT-1800i测定WBC、RBC、Hb、PLT、HCT五项指标并进行比对,并从中随机抽取5个健康体检标本的Sysmex XS-800i分类结果与手工分类结果进行比较。结果 Sysmex XS-800i的准确性、批内及批间精密度、携带污染率、稀释效果、总重复性均在允许范围内,Sysmex XS-800i和Sysmex XT-1800i对WBC、RBC、Hb、PLT、HCT的测定结果经统计学分析无显著性差异(P>0.90),Sysmex XS-800i分类结果与手工分类结果进行比较,相关性较好。结论 Sysmex XS-800i是一种较理想的全自动血细胞分析仪,性能良好,检测结果与显微镜目测有良好的一致性;检测快速、准确、重复性好,可用于医院实验室对批量全血标本血细胞分析进行有效的筛选。

Performance Evaluation of Sysmex XS-800i Automated Hematology Analyzer

Objective To evaluate the function of the Sysmex XS-800i automated hematology analyzer. Method The accuracy, within-batch and between-batch precision, carryover pollution rate, effect of dilution, overall precision and the reproducibility of white blood cell detection were analyzed. Blood samples from 22 healthy people or patients were tested by Sysmex XS-800i and the Sysmex XT-1800i respectively. Five indexes including WBC, RBC, Hb, PLT and HTC from two tests were compared. And the results of five healthy specimens which are selected randomly classified by the Sysmex XS-800i were compared with those by handwork. Result The accuracy, within-batch and between-batch precision, carryover pollution rate, effect of dilution and the overall precision of Sysmex XS-800i were all in the allowable range. The statistical results of WBC, RBC, Hb, PLT and HCT tested by Sysmex XS-800i showed no significant changes compared with those by Sysmex XT- 1800i （P 〉 0.90）. The results of Sysmex XS-800i showed excellent correlation with those by handwork. Conclusion The performance of the Sysmex XS-800i automated hematology analyzer is satisfying. The results are coincident with visual test by microscope. It can complete the test quickly, and the result is accurate and repeatable, so it can be used in hospital laboratory to screen effectively the analysis of batch of whole blood sample of the hemocyte.
