摘要
目的:了解济南市临床输血相容性检测室间质量评价情况,规范临床输血检验质量管理,提高我市整体输血相容性实验的检测水平。方法:对2016—2019年济南市临床输血检测实验室每年进行2次输血相容性室间质量评价。输血相容性检测室间质评的项目包括:红细胞ABO血型(正定型和反定型)、RhD血型、不规则抗体筛选、交叉配血。质控品设计实现了双盲检测,实验结果进行网络直报。结果:室间质评活动参加单位数量由2016年的42家,2017—2018年的49家,2019年增加到58家。2016—2017年有1家单位未开展不规则抗体筛选项目,2018—2019年输血相容性检测项目参加单位均已开展;室间质评扣分项共计132个:交叉配血错误37个、样本漏报27个、不规则抗体筛选(抗筛)错误24个、项目未开展20个、笔误9个、理解及表述不准确错误6个、血型错误8个、方法选择错误1个。不规则抗体筛选及交叉配血的实验方法学统计显示微柱凝集法比凝聚胺法合格率高,差异有统计学意义(P<0.05)。结论:室间质评活动参加单位数量逐年增加;各参加质评单位输血相容性检测项目逐年完善和规范;检测的实验方法逐渐规范;室间质评项目合格率逐年上升,经过这几年的室间质评活动各实验室的技术状态、整体检测能力和工作人员能力水平都有所提升。
Objective:To understand the external quality evaluation of clinical blood transfusion compatibility test in Jinan,standardize the quality management of clinical blood transfusion test,and improve the detection level of the whole blood transfusion compatibility test in our city.Methods:The quality of compatibility of blood transfusion was evaluated twice a year in Jinan clinical blood transfusion testing laboratory from 2016 to 2019.The items of external quality assessment for blood transfusion compatibility testing included ABO(positive and negative stereotyping)blood types of erythrocytes,RhD blood type,irregular antibody screening and cross matching.Double blind detection was realized in the design of quality control product,and the experimental results were directly reported on the network.Results:The number of participants increased from 42 in 2016,49 in 2017-2018 and 58 in 2019.From 2016 to 2017,one unit did not carry out irregular antibody screening project,and all participating units of blood transfusion compatibility test project had carried out from 2018 to 2019.There were 132 deduction items in the external quality assessment,including 37 cross matching errors,27 missing samples,24 irregular antibody screening(anti screening)errors,20 projects not carried out,9 written errors,6 inaccurate understanding and expression errors,8 blood type errors and 1 error in method selection.Statistical analysis of irregular antibody screening and cross matching showed that the qualified rate of microcolumn agglutination method was higher than that of polyamine method,and the difference was statistically significant(P<0.05).Conclusion:The number of participating units in the activity of external quality assessment was increasing year by year;the items of blood transfusion compatibility testing of each participating quality assessment unit were improved and standardized year by year.The experimental methods of testing were gradually standardized.The qualified rate of the items of external quality assessment was increasing year by year.After the activities of external quality assessment in recent years,the technical status,overall detection ability and staff ability level of each laboratory had been improved.
