血液分析仪与外周血涂片镜检在恶性血液病诊断中作用的评价

目的:分析全自动血液分析仪及外周血涂片镜检两种检查手段在初诊恶性血液病诊断中的价值。方法:用日本东亚公司NS- 1500 型全自动血液分析仪及外周血涂片镜检作瑞氏染色检查外周血白细胞分类。结果:148 例恶性血液病中,用NS- 1500 型全自动血液分析仪及外周血涂片镜检幼稚细胞的检出率分别为:83-7 % (124/148) 、79-9 % (118/148) ,P> 0 .05 。外周血涂片镜检未检出幼稚细胞的病人中,有2 例M2 病人用NS- 1500 全自动血液分析仪做外周血白细胞计数和分类时仪器提示有异常。但用NS- 1500 型全自动血液分析仪检查各种不同类型幼稚细胞的鉴别有时会有误差。结论:全自动血液分析仪与外周血涂片镜检是两种各具特有功能的检查手段,在临床诊断中,只有互相结合,取长补短,才能使血液病诊断的准确率提高到一个新水平。

THE DIAGNOSTIC VALUE OF AUTOMATIC BLOOD ANALYSIS AND MICROSCOPIC EXAMINATION OF PERPHERAL BLOOD SMEAR IN PATIENTS WITH HEMOPOIETIC MALIGNANCE

Objectives:To analyse the diagnostic value of automatic blood analysis and microscopic examination of perpheral blood smear in patients with hemopoietic malignance on first visit.Methods:The Japanese Easthern Asra Corporation NS-1500 automatic blood analysis was used and microscopic examine the differantiated lount of WBC.Results:In 148 cases of hemopoietic malignance,the detective reats of blast by NS-1500 automatic blood analysis and microscopic examination of perpheral blood smear were 83.7% (124/148) and 78.3%(116/148) respectively (P>0.05).In cases of negative blast detection by microscopic examination of peripheral blood smeas.two leukamic patients (FAB M 2) showed abnormalty in differentiated count of WBC by automatic blood analysis.But NS-1500 automatic blood analysis has difficalty differenciating different kind of blast sometimes.Conclusions:Automatic blood analysis and microscopic examination of perpheral blood smear are two specific methods in clinical diagnosis,If we use both of them,the correct rate of diagnosis should be improved.
