自身抗体引起的疑难配血分析

The difficulty with autoantibodies cause blood analysis

目的:分析自身抗体在血清学检测中的特性,以保证临床输血安全、及时、有效,以保障患者生命安全。方法:对送检患者的血清进行不规则抗体筛查,用盐水法、聚凝胺法、微柱凝胶卡式法进行交叉配血。结果:自身抗体和所有红细胞均出现凝集反应。结论:由于红细胞直抗阳性,在配合试验中主侧次侧均发生凝集现象时,主要考虑主侧配血,选择"最小不相容性"的同型洗涤红细胞进行输注。

Objective Analysis autoantibody in serology detection of characteristics, in order to ensure clinical transfusion safety, timely, effective, in order to ensure the patient life safety. Methods Patients with cleared the serum of irregular antibody screening, with brine method, polybrene method, micro column gel cassette method for cross matching. Results Autoantibody and all red blood cells all appear agglutination reaction. Conclusion Because of red blood cell direct resistance to positive, with test in the main side primary side occurs agglutination phenomenon, mainly consider the main side matching, choose “minimum incompatibility” of the same type washing red blood cells for infusion.
