  RDW作为IDA(缺铁性贫血)的早期诊断指标,比贮存铁各项指标的测定简便快捷,特别适合于日程的诊治工作。当发现HGB和MCV正常,而有RDW增大时,即可对铁不足作出判断。此时应给予铁剂治疗以补足储备铁,使RDW恢复正常,避免发展为临床期贫血。

  干扰因素:冷凝集素,高血糖症,慢性淋巴细胞性白血病,死后红细胞输血。
  干扰因素:冷凝集素,高血糖症,慢性淋巴细胞性白血病,死后红细胞输血。红细胞分布直方图的基底宽度,细胞仪自动计算,可用MCV的SD表示,但必须结合MCV评价;故较常用MCV的变异系数(CV)值表示,即RDW(CV%)=SD%%sub MCV/%/MCV。

标本采集:除卧床病人外,一般采取坐位。成人一般从肘静脉取血,在采血前应静坐5min。使用止血带的时间不超过1min。EDTA-K2抗凝血(浓度为150-180g/L),静脉抽血2ml,立即颠倒混匀,防止凝固。\\
标本运送:试管上粘贴唯一标识号,该标识号可以是条形码,也可以是申请单的联号。如果是条形码包含患者姓名、检验目的、标本类型、标本采集日期等信息。如需将标本从原始采血管中转移到新的采血管时,新的采血管要有与原采血管信息一致的标识。\\
