缺铁性贫血(iron deficiency anemia, IDA)是由于体内储存铁缺乏而影响血红蛋白合成所引起的一种常见贫血。这种贫血特点是骨髓、肝、脾及其他组织中缺乏可染色铁,血清铁浓度和血清转铁蛋白饱和度均降低。典型病例贫血是属于小细胞低色素型。铁缺乏症根据体内缺铁的发展过程,分体内储存铁耗尽(iron depletion,ID)、缺铁性...
机体对铁的利用是极为有效和节省的,每日合成血红蛋白需要的铁(20-25mg),大部分来自衰老的红细胞破坏后释放的铁。 缺铁对细胞的分裂、增殖影响较小,故红细胞数量减少程度不如血红蛋白减少明显。 血清铁(serum iron,SI) 血清中的铁一部分与运铁蛋白结合,另一部分呈游离状态,检测后者的含量即为血清铁测定。受生理...
缺铁性贫血是指体内铁含量不足时发生的贫血。患贫血时,人的红细胞(RBC)数量比正常人低。 红细胞内的血红蛋白担负者向全身输送氧气的功能。铁是合成血红蛋白的重要原料。铁不足时,血红蛋白和红细胞生成减少,从而导致贫血。补铁治疗通常会使贫血好转。 体征和症状 初期,缺铁性贫血的儿童可能没有任何症状。如果未能及...
