摘要: 目的 对住院患者进行不规则抗体筛查和抗体鉴定,并对结果及阳性率进行分析,探讨其特异性和临床意义,为临床安全输血提供帮助。方法 通过医院信息系统(HIS)和检验系统(LIS)收集患者基本信息、输血史、妊娠史、抗体的数量和特异性。收集了52 265例住院患者的临床资料,不规则抗体鉴定阳性195例,其中男61例,女134例;有输血史58例,无输血史137例;有妊娠史126例,无妊娠史8例。结果 住院患者不规则抗体阳性率为0.37%,Rh血型系统抗体、MNS血型系统抗体、Lewis血型系统抗体最为常见,其中抗E阳性45例(23.08%),抗Ec阳性12例(6.15%),抗D阳性7例(3.59%),抗M阳性47例(24.10%),抗Lea 23例(11.79%),混合抗体5例(2.56%),未确定特异性抗体41例(21.03%)。在女性患者中,Rh血型系统抗体占40.30%,高于对照组(P < 0.05);在有输血史中,Rh血型系统抗体56.90%,高于对照组(P < 0.05),无输血史中,MNS血型系统抗体31.39%、Lewis血型系统抗体17.52%,高于对照组(P < 0.05);在有妊娠史中,Rh血型系统抗体41.27%,MNS血型系统抗体21.43%,Lewis血型系统抗体11.90%,略高于对照组,但差异无统计学意义(P>0.05)。结论 对输血患者进行抗体筛查并对阳性的进一步鉴定,结合本区域抗体的特点改变实验流程和选择合适的试剂等,可以提高抗体检测水平、减少不良反应的发生,提高输血安全。同时可以避免对有生育潜力女性的致敏作用,达到优生优育目的。Abstract: Objective To investigate the specificity and clinical significance of irregular antibody screening and antibody identification in hospitalized patients, and analyze the results and positive rate, so as to provide help for clinical safe blood transfusion.Methods The basic information of patients, transfusion history, pregnancy history, antibody quantity and specificity were collected through hospital information system(HIS) and laboratory information system(LIS). The clinical data of 52 265 inpatients were collected. 195 cases were positive for irregular antibody, including 61 males and 134 females. 58 cases had transfusion history, 137 cases had no transfusion history. There were 126 cases with pregnancy history and 8 cases without pregnancy history.Results The positive rate of irregular antibody was 0.37%. Rh blood group system antibody, MNS blood group system antibody and Lewis blood group system antibody were the most common. Among them, 45 cases(23.08%) were anti-E positive, 12 cases(6.15%) were anti-Ec positive, 7 cases(3.59%) were anti-D positive, 47 cases(24.10%) were anti-M positive, 23 cases(11.79%) were anti-Lea positive, 5 cases(2.56%) were mixed antibody and 41 cases(21.03%) were undetermined specific antibody. In female patients, Rh blood group system antibodies accounted for 40.30%, which was higher than that of the control group(P < 0.05). In the patients with transfusion history, Rh blood group system antibody was 56.90% higher than that of the control group(P < 0.05). In the patients without transfusion history, MNS blood group system antibody was 31.39% and Lewis blood group system antibody was 17.52% higher than that of the control group(P < 0.05). In the pregnant group, Rh blood group antibody(41.27%), MNS blood group antibody(21.43%) and Lewis blood group antibody(11.90%) were higher than those in the control group, but there was no statistical significance(P>0.05).Conclusion Antibody screening for transfusion patients and further identification of positive results, changing the experimental process and selecting appropriate reagents according to the characteristics of antibodies in the region could improve the antibody detection level, reduce the occurrence of adverse reactions and improve blood transfusion safety. Meanwhile, the sensitization effect on females with fertility potential could be avoided, and the aim of eugenics and better rearing could achieved.
