摘要:
目的 分析直接抗人球蛋白试验(DAT)阳性患者的血型血清学特征,为临床输血安全提供保障。方法 对51例DAT阳性患者的DAT阳性强度、DAT分型及自身抗体和同种抗体的鉴定结果进行回顾性分析。结果 51例中,W+(弱凝集)者16例(31.4%),1+者15例(29.4%),2+者19例(37.3%),3+者1例(1.9%)。单IgG者15例(29.4%),单C3d者10例(19.6%),IgG+C3d者26例(51.0%)。不规则抗体筛查试验阳性42例,阴性9例。经16系谱细胞进行抗体鉴定,在盐水介质下检测抗体阳性22例,其中无特异性18例,有特异性4例;用间接抗人球蛋白试验检测抗体阳性31例,其中无特异性16例,有特异性15例。结论 DAT阳性患者应进行DAT分型试验和同种抗体鉴定试验,根据试验结果选择适合的血液,以保障临床输血的及时性、安全性和有效性。
Abstract:
Objective To provide a guarantee for clinical transfusion safety by analyzing the serological characteristics of blood type of patients with positive direct antiglobulin test (DAT).Methods The results of DAT positive intensity,DAT typing,the identification of autoantibody and isoantibody in 51 patients with positive DAT were analyzed retrospectively.Results The DAT positive intensity of the 51 cases included W+(weak agglutination) in 16 cases(31.4%),1+ in 15 cases(29.4%),2+ in 19 cases(37.3%) and 3+ in 1 case.The DAT types of the 51 cases included IgG in 15 cases(29.4%),C3d in 10 cases(19.6%) and IgG+C3d in 26 cases(51.0%).Among the 51 cases,the irregular antibody screening test was positive in 42 cases,and it was negative in 9 cases.The 16 pedigree cell antibody identification results showed that the antibody was positive in 22 cases,including 18 cases without specificity and 4 cases with specificity in saline medium.The indirect anti globulin test was positive in 31 cases,including 16 cases without specificity and 15 cases with specificity.Conclusion DAT typing test and isoantibody identification in the patients with positive DAT are necessary.The matching blood can be chosen according to the test results,which can ensure the timeliness,safety and effectiveness of clinical blood transfusion.
