红细胞体积分布宽度在缺铁性贫血和轻型地中海贫血诊断中的应用

Application of RDW in Diagnosing IDA and Thalassemia

目的分析采用红细胞体积分布宽度(RDW)筛检缺铁性贫血和轻型地中海贫血的临床价值。方法从东华医院微机中随机抽取近期血常规检测结果,其中缺铁性贫血52例、轻型地中海贫血36例(轻型-β-地贫28例、轻型-α-地贫8例)和正常人330例,分析血常规中RDW检测值与贫血的关系。结果正常人RDW10.5%～14.5%,缺铁性贫血RDW>14.5%,符合率为100%;轻型地中海贫血RDW<14.5%,β-地中海贫血符合率为89%,α-地中海贫血符合率为75%。结论RDW在筛查缺铁性贫血和轻型地中海贫血中有重要意义。

[Objective] To analyze the clinical value of red blood cell volume distribution width (RDW) in screening iron deficiency anemia (IDA) and thalassemia. [Methods] The blood samples of 52 cases of IDA, 36 cases of thalassemia and 330 healthy people were collected; the correlation between RDW value and anemia was analyzed. [Results] RDW of the healthy people was 10.5% to 14.5%; that of the IDA (100%) was over14.5%; that of the thalassemia (89% of β- thalassemia,89% of α- thalassemia) was under 14.5%. [Conclusion] RDW has a significant value in screening IDA and thalassemia.
