目的分析影响部队团体献血ABO血型初筛检测错误的原因,提出改进措施,提高准确性。方法采用回顾性调查的方法,对本血站2006年1月-2015年12月部队团体献血482批次68 074人次ABO血型初筛错误进行统计,采用SPSS统计软件对相关因素进行分析。结果 10年ABO血型初筛检测错误272人次(0.40%),与不同批次采血人数分级比较无差异(P>0.05);夏季ABO血型初筛的错误率(0.54%)高于其它季节(P<0.05);B抗原漏检所致误判率(34.95%)高于其它原因。结论部队团体献血人数的增加与ABO血型初筛错误率无关,影响因素主要为试剂效价、环境温度及人为因素。组织团体献血应合理安排工作流程,严格操作规范、加强人员责任心,最大限度的降低血型初筛错误率。
Objective To analyze the causes of ABO blood group screening error that affect the blood donation of military units and propose the improvement measures to improve the accuracy. Methods A retrospective survey method was used to count 68 074 ABO blood typing errors in 482 batches of blood donations from January 2006 to December 2015 in our blood station. SPSS statistical software was used to analyze the relevant factors. Results There were no significant differences in the number of ABO blood samples (272 cases) (0.40%) at 10 years, and there was no difference (P> 0.05) <0.05). The misjudgment rate (34.95%) caused by missed B antigen was higher than other reasons. Conclusion The increase of blood donation in army group is not related to the error rate of ABO blood type preliminary screening. The main influencing factors are reagent potency, ambient temperature and human factor. Organizational blood donation should organize the work flow, strictly regulate the operation, strengthen the sense of responsibility of personnel, and minimize the error rate of blood type screening.
