【摘要】 目的 探讨影响血液细胞分析仪测定白细胞分类的因素，排除假性增高和假性降低情况，必要时必须血片复核，准确地为临床提供可靠的诊治依据。 方法 使用Sysmex KX-21血液细胞分析仪及目视显微镜，同时对150例标本进行检查，对比分析。结果 操作不顺利、标本采取后放置时间、温度及上机前标本混匀、振荡时间、力度等均可影响血液细胞分析仪正确对白细胞的分类。结论 血液细胞分析仪并不能完全代替目视显微镜进行白细胞分类，对出现疑有异常白细胞警告报警，应分析原因，目视显微镜下白细胞分类或重新采血。

    【Abstract】 Objective To discuss the factors that can effect the blood cells analyer to measure the classification of leukcyte and remove the situation of the pseudo increasing and decreasing and push a blood piece to examine and provide the clinical doctors with the reliable indentification of diagnosis and treatment accurately. Methods With the Sysmex KX-21 blood cell analyer and the visual microscope,150 blood specimens were examinecl and had the constrary analysis in one time.Results Being unsmooth on operation, setting aside the specimens for a long time after collecting, the temeprature and the mixture of specimens, the duration and power of osillation and so on are all effect the accurate classification of leukcyte in the blood cells analyer. Conclusions The blood cells analyer cannot compeletely replace the visual microscope to examine the classification of leakcyte. When appearing the doubts and warning reports on the unusual leakcyte, reasons should be analied and classification should be in the visual microscope or blood specimen should be collected again. ......
