摘要 目的探讨可溶性转铁蛋白受体/铁指数(sTfR-F)对慢性肾衰竭(CRF)所致缺铁性贫血(IDA)的诊断价值。方法对97例单纯IDA患者(IDA组)、60例未合并IDA的CRF患者(CRF组)及63例CRF所致慢性肾性贫血(CRA)患者(CRA组)进行血常规及血清铁蛋白(SF)、总铁结合率(IBCT)、转铁蛋白受体(TfR)和可溶性转铁蛋白受体(sTfR)检测,以公式sTfR/logSF计算sTfR-F,评估各项指标对疾病的诊断价值。结果 IDA组sTfR和sTfR-F水平高于CRF组和CRA组(P<0.05);sTfR和sTfR-F对IDA的诊断灵敏度分比为82.0%和88.7%,诊断特异度分别为88.3%和100.0%。结论 sTfR和sTfR-F对CRA具有较高的诊断特异度和灵敏度,可用于评估CRA患者铁缺乏程度。
