背景:铁缺乏症在幼儿期常见,且与发育延迟有关。目前还不知道铁缺乏的指标在确定真正的铁缺乏和评价口服铁剂治疗效果方面的可信度有多高。方法:研究对象为Millennium儿童研究组织的儿童。笔者采集13个月儿童的静脉血样本,测定其平均红细胞容积(MCV)、血红蛋白、红细胞平均血红蛋白含量(MCH)、铁蛋白和锌原卟啉(ZPP)。测量结果异常的儿童将接受口服铁剂 Background: Iron deficiency is common in early childhood and is associated with delayed development. It is unknown at this time how high the credibility of iron-deficiency indicators is in determining true iron deficiency and evaluating the efficacy of oral iron therapy. Methods: Children of the Millennium Children’s Research Group were studied. The author collected 13-month-old children’s venous blood samples, measured the average volume of red blood cells (MCV), hemoglobin, erythrocyte mean hemoglobin content (MCH), ferritin and zinc protoporphyrin (ZPP). Children with abnormal measurements will receive oral iron
