隐性缺铁性贫血是指机体储存铁已经减少,但贫血尚未发生的一种亚临床状态,发生率高于缺铁性贫血。儿科医师常根据血色素来评价儿童是否贫血,易忽略隐性缺铁性贫血(1DE)的存在。近年来有报道根据红细胞平均体积(MCV)下降和红细胞体积分布宽度(RDW)升高诊断缺铁性贫血。就此我们以骨髓可染铁明显减少作为铁缺乏的诊断依据,观察MCV下降、RDW升高与缺铁的相关性,报告如下: Recessive iron deficiency anemia refers to the body has reduced iron storage, but anemia has not yet occurred in a subclinical state, the incidence is higher than iron deficiency anemia. Pediatricians often based on hemoglobin to assess whether the children anemia, easy to overlook the existence of latent iron deficiency anemia (1DE). In recent years, it has been reported that the diagnosis of iron deficiency anemia is based on the decrease of the mean corpuscular volume (MCV) and the increase of the width of the red blood cell volume distribution (RDW). In this regard, we can significantly reduce bone marrow can be used as a diagnostic basis for iron deficiency, observed MCV decreased RDW increased iron deficiency, the report is as follows:
