摘要
目的 了解β－地中海贫血患儿红细胞、血小板体积分布直方图对判断血小板计数结果所起的作用。 方法 采用Abott公司Cell－DYN 3500血细胞分析仪对51例β－地贫患儿及40例健康查体对照儿童进行血常规分析及人工血小板计数，同时涂片瑞氏染色后油镜检查。 结果 发现正常对照组血小板人工计数值与仪器计数值无显著性差异（P＞0．05），而β－地贫患儿组红细胞及血小板直方图均呈异常改变，出现RBC MORPH及URI报警。血小板仪器计数结果明显高于人工显微镜计数（P＜0．05）。 结论 由此说明对于β－地贫患儿，应通过对其红细胞、血小板直方图的观察，结合显微镜人工计数及涂片染色镜检，方能得出血小板的准确计数结果。
Objective To study the effect of RBC and platelet (PLT) histogram on judging the result of PLT count in children with β－thalassemia (β－thal)． Method Using CELL－DYN 3500 full automation hemology analyzer we examined routinely specimens from 51 β－thal and 40 healthy control children and counted the PLT manually． Simultaneously these specimens were made smear stained by Wright stain and examined under oil immersion microscopically Result The test showed that there was no significant difference (P＞0．05) between the PLT count by hand and that by analyzer in the control group while in the β－thal group the RBC and PLT histogram were abnormal in accompany with RBC MORPH and URI alarm the results of PLT count by analyzer were obviously higher than that by manual count (P＜0．05)． Conclusion These illustrate that for β－thal children only through observing the RBC and PLT hisogram combining manual PLT count with microscopic morphological examination we can obtain the accurate PLT count results．
