目的:制备游离血红蛋白(FHb)室内质控物,并对其性能进行评价。方法①选取5份已知血红蛋白(Hb)浓度的正常人类全血,用蒸馏水分别以1∶500,1∶1000,1∶2000,1∶4000的比例进行稀释,充分混匀后配制成20份 FHb 溶液,检测其 FHb 浓度,并与其理论浓度进行比较。②选择高值、低值溶液各1份,作为日常室内质控物,混匀分装-20℃保存,常规条件下连续检测20天,计算两组的珚x,s 和 CV 值,绘制 Levey-Jennings 质控图;之后每周测定一次,将数据依次标记在质控图上,直至更换试剂批号;计算高值、低值两种质控物整个检测周期内的总体珚x,s 和 CV 值。结果①该20份标本的 FHb 浓度理论值和实测值(-x±s)分别为125.44±93.04 mg/L 和125.22±93.08 mg/L,差异无统计学意义(t=0.706,P >0.05)。②高值、低值质控物连续20天检测结果(-x±s)分别为303.55±3.70 mg/L 和69.29±1.88 mg/L,CV 值分别为1.22%和2.68%;高值、低值质控物整个检测周期内结果均未失控,总体(-x ±s)分别为302.56±3.99 mg/L 和69.04±1.88 mg/L,CV 值分别为1.32%和2.71%。结论FHb 室内质控物制备过程简单,质量可靠,稳定性好,适合在血站和临床实验室中应用和推广。

Objective To prepare an internal quality control substance of free hemoglobin (FHb),and evaluate its perform-ance.Methods ① 5 normal whole human blood samples with known hemoglobin (Hb)concentration was selected and dilu-ted with distilled water in the ratio of 1∶500,1∶1 000,1∶2 000,1∶4 000 respectively.After 20 FHb solutions was fully mixed,the concentration of FHb solutions was tested and compared with its theoretical data.②One of the highest value and the lowest value solutions were chosen as qualitye control substance,packed and stored in -20℃ fridge.Each group was an-alyzed 20 days continuously in the routine conditions,where average (-x )of the groups,standards deviation (s )and coeffi-cients of variation (CV)were calculated and Levey-Jennings control chart was conducted.Then,the test was repeated every week,and the data on the chart was updated accordingly until (CV)of the reagents were changed.The average (-x)of the-groups,standards deviation (s)and coefficients of variation uality control material was calculated during the whole test peri-od.Results ①The theoretical value (-x ±s)of the concentration of free hemoglobin was 125.44±93.04 mg/L,and the actu-al value was 125.22±93.08 mg/L,there was no statistic significance (t value was 0.706,P >0.05).② During 20 continu-ously daystest,the detected values (-x ±s)of the highest quality control material was 303.55±3.70 mg/L;the values of the lowest quality control material was 69.29 ± 1.88 mg/L.The coefficients were 1.22% and 2.68% respectively.Both the highest and the lowest quality control material were under control during the whole detecting period.The (-x ±s )values of the highest was 302.56±3.99 mg/L,the CV value of it was 1.32%;The (-x ±s)values of the lowest was 69.04±1.88 mg/L,the CV value of it was 2.71%.Conclusion The preparation method of internal quality control substance of free hemoglo-bin is convenient and stable,and was applicable in blood station’s and clinical laboratory.
