摘　　要：目的:探讨贫血患者红细胞体积分布宽度的变化及其临床意义。方法:应用sysm ex F-820血细胞分析仪测定164例贫血患者红细胞体积分布宽度变异系数(RDW-CV)。结果:M CV↓RDW↑缺铁性贫血、M CV↑RDW↑巨幼红细胞性贫血、M CV和RDW异常,急性再生障碍性贫血、M CV↑RDW,慢性再生障碍性贫血、M CV↑RDW↑溶血性贫血、M CV、RDW↑铁粒幼细胞性贫血、M CV↓RDW,单纯小细胞性贫血。结论:RDW指标的改变对贫血的分类及缺铁性贫血的诊断有较好的敏感性和特异性。Objective：To explore the changes and clinic significance of red blood cell volume distribution width in anemic patients. Methods： We determined coefficient of variation of red blood cell volume distribution width（CDW--CU） in 164 anemic patients with Sysmex F-820 blood cell analyzer device. Results：In iron deficiency anemia,MCV ↓, and RDW↑ ;in megaloblastic anemia,MCV ↑and RDW ↑, ;in acute aplastic anemia, the normality of MCV and RDW; in chronic aplastic anemia, MCV↑ and the normality of RDW;in hemolytic anemia, MCV↑and RDW↑ ;in sideroblastic anemia, the normality of MCV and RDW ↑ ;in simple small cellulars anemia,MCV↓, and the normality of RDW. Conclusion：The changes of RDW are sensitive and specificity in the classification of anemia and the diagnosis of iron deficiency anemia.
