目的不同贫血红细胞体积的变化,使红细胞体积分布图发生变化。探讨不同贫血其红细胞直方图及其红细胞平均体积(MCV)、红细胞分布宽度(RDW)的不同变化,对鉴别贫血类型及疗效观察的临床应用。方法采用迈瑞BC-5380全自动血液细胞分析仪对50例正常对照者和150例我院住院贫血患者外周血进行血常规检测。结果不同贫血MCV、RDW的改变各有特征,红细胞直方图也可发生不同变化。结论红细胞直方图结合MCV、RDW对各类贫血的鉴别诊断具有较高的敏感性和特异性,对疗效观察有一定的临床意义。
The purpose of different anemia changes in the volume of red blood cells, so that changes in the volume distribution of red blood cells. To investigate the different changes of erythrocyte histogram, erythrocyte histogram and erythrocyte mean volume (MCV) and erythrocyte distribution width (RDW) in different anemia and its clinical application in identifying anemia type and curative effect. Methods The peripheral blood samples of 50 normal controls and 150 hospitalized patients with anemia in our hospital were detected by Mindray BC-5380 automatic hematology analyzer. Results Different anemia MCV, RDW changes have their own characteristics, red blood cell histogram may also have different changes. Conclusion The combination of erythrocyte histogram with MCV and RDW has high sensitivity and specificity for the differential diagnosis of various types of anemia and has some clinical significance for the observation of curative effect.
