血细胞形态及血常规指标MCV、MCH、MCHC、RDW对婴幼儿缺铁性贫血的诊断价值

摘要

目的 探讨血细胞形态检测及血常规指标MCV、MCH、MCHC、RDW对婴幼儿缺铁性贫血的诊断价值.方法 分别根据血细胞形态及血常规指标MCV、MCH、MCHC、RDW判定为小细胞低色素性贫血病例并收集,同时检测所有病例的血清铁蛋白和血清铁.分别分析两种方法所判定的小细胞低色素性贫血中缺铁性贫血的阳性率;再联合两种方法,观察它们在诊断缺铁性贫血中的价值.结果 根据血细胞形态所判定为小细胞低色素性贫血中最后确诊为缺铁性贫血的占70.5％;由血常规指标MCV、MCH、MCHC、RDW判定为小细胞低色素性贫血中最后确诊为缺铁性贫血的占83.8％;联合血细胞形态及血常规指标MCV、MCH、MCHC、RDW判定为小细胞低色素性贫血中最后确诊为缺铁性贫血的占94.9％.结论 分别检测血细胞形态及血常规指标MCV、MCH、MCHC、RDW对缺铁性贫血诊断具有一定的价值,若联合检测可显著提高缺铁性贫血的检出率.%Objective To study the value of blood cell morphology and blood routine indexes,MCV,MCH,MCHC,and RDW,for diagnosing iron deficiency anemia (IDA) in infants.Methods According to the blood cell morphology and blood routine indexes,MCV,MCH,MCHC,and RDW,the microcytic anemia cases would be collected respectively;at the same time,all the cases' serum ferritin and iron were detected.The positive rates of iron deficiency anemia in the cases diagnosed with small cell hypochromic anemia by these two methods were analyzed;and the value of the combination of these two methods in the diagnosis of IDA was observed.Results The positive rate of iron deficiency anemia in the cases diagnosed with small cell hypochromic anemia by blood cell morphology was 70.5％,that by blood routine indexes,MCV,MCH,MCHC,and RDW,was 83.8％,and that by the combination of these two methods was 94.9％.Conclusions Blood cell morphology and blood routine indexes,MCV,MCH,MCHC,and RDW have certain value in the diagnosis of IDA.And the combination of these two methods can significantly improve the detection rate of IDA.
