血常规检测在鉴别缺铁性贫血和地中海贫血中的应用

The Application of Routine Hematological Examination in Differential Diagnosis between IDA and THAL

目的探讨血常规检测在缺铁性贫血与地中海贫血鉴别诊断中的价值。方法选择我院门诊与住院缺铁性贫血患者80例及地中海贫血患者30例,正常人50例,对所有对象进行血常规检测,对比其血常规检测项目差异。结果 IDA组RBC计数显著低于正常对照组及THAL组,但THAL组显著高于正常组(P<0.05);两疾病组Hb与正常对照组相比显著减低,且IDA组Hb显著低于THAL组(P<0.05);THAL组及IDA组的MCV与正常对照组相比均显著降低(P<0.05),IDA组与THAL组相比无显著差异(P>0.05),两疾病组RDW均显著高于正常组,THAL组显著低于IDA组(P<0.05)。结论 MCV是诊断小细胞低色素性贫血良好指标,RDW可作为缺铁性贫血与地中海贫血的鉴别诊断要点。

Objective To investigate the effect on differentiation between IDA and THAL in routine hematological examination.Methods Routine hemato logical examination was performed on 80 patients with IDA,30 patients with THAL and 50 health adult.Result RBC of IDA group was significantly lower than the control group and THAL group and RBC of THAL group was significantly higher than the control group（P〈0.05）;Hb of the two anaemic groups were significantly lower than the control group and Hb of IDA group was significantly lower than THAL group（P〈0.05）;MCV of the two anaemic groups were significantly lower than the control group,MCV of the two anaemic group had no significantly diffrernce（P〉0.05）;RDW of the two anaemic groups were significantly higher than the control group and RDW of THAL was Significantly lower than IDA group.Conclusion MCV is a good index in diagnosing small-cell anemia hypochromic,and RDW can be used as the point of differential diagnosis between iron-deficiency anemia and thalassemia.
