目的:探讨网织红细胞血红蛋白当量(Ret-He)在诊断单采血小板女性献血者潜伏期铁缺乏中的应用价值.方法:选择2022年1月至2月在福建省血液中心进行血小板捐献的230例女性献血者,根据缺铁严重程度将其分为正常组、储铁缺乏(ID)组和缺铁性红细胞生成(IDE)组.采用Sysmex-XN全自动血液分析仪检测血红蛋白浓度(HGB)、平均红细胞体积(MCV)、平均红细胞血红蛋白含量(MCH)、红细胞分布宽度变异系数(RDW-CV)和Ret-He,通过化学发光法检测所有入选者的铁生化指标.运用受试者工作曲线(ROC)评价相关指标对女性献血者潜伏期铁缺乏的诊断价值.结果:ID组的Ret-He为32.55(31.15,33.10)pg,明显低于正常组[33.80(32.73,34.70)pg](P＜0.05),且明显高于 IDE 组[30.40(28.70,31.50)pg](P＜0.05).HGB、MCV、MCH、RDW-CV 和Ret-He诊断女性献血者IDE的ROC曲线下面积分别为0.892、0.843、0.909、0.890、0.931;其中当Ret-He的临界值为32.05 pg时,其灵敏度和特异度分别为85.90％和92.60％,各红细胞参数对ID的诊断价值均较差.结论:Ret-He 可作为单采血小板女性献血者潜伏期铁缺乏的良好指标,通过检测Ret-He能够将女性献血者铁缺乏的发现提前到IDE阶段.
The Diagnostic Value of Ret-He in Predicting Latent Iron Deficiency in Female Blood Donors
Objective:To explore the application value of reticulocyte hemoglobin equivalent(Ret-He)for diagnosing latent iron deficiency in female plateletpheresis donors.Methods:A total of 230 female plateletpheresis donors in Fujian Blood Center from January to February 2022 were selected as the research group and divided into three groups:normal group,iron depletion(ID)group and iron deficient erythropoiesis(IDE)group,according to the severity of iron deficiency.The level of hemoglobin(HGB),mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH),coefficient of variation of red cell distribution width(RDW-CV)and Ret-He were measured by using the Sysmex XN automated hematology analyzer.Chemiluminescence immunoassay was used to detect iron biochemical indexes.Receiver operating characteristic(ROC)curve analysis was performed to evaluate the diagnosic value of relevant indicators in female blood donors with latent iron deficiency.Results:Ret-He in ID group was 32.55(31.15,33.10)pg,which was significantly lower than that in the normal group[33.80(32.73,34.70)pg](P＜0.05),and significantly higher than that in IDE group[30.40(28.70,31.50)pg](P＜0.05).ROC analysis in diagnosis of IDE demonstrated that the area under the curves(AUCs)of HGB,MCV,MCH,RDW-CV and Ret-He were 0.892,0.843,0.909,0.890,0.931,respectively.When the critical value of Ret-He was 32.05 pg,its sensitivity and specificity were 85.90％and 92.60％,respectively.However,all red blood cell parameters had poor diagnostic value for ID.Conclusion:Ret-He is a perfect predictor for latent iron deficiency in female blood donors.Detection of Ret-He can advance the diagnosis of iron deficiency in female blood donors to the IDE stage.
