患者输血前初、复检血型不符和不规则抗体筛查结果调查

The clinical application of preliminary and re-examination of blood types and irregular antibody screening before blood transfusion

目的探讨输血前对患者进行血型初、复检和不规则抗体筛查的临床应用价值。方法 2009年1月-2014年6月,对7 751名患者采用试管法进行输血前血型初检,微柱凝胶技术进行血型复检、不规则抗体筛选和鉴定。结果 7 751名患者中,共检出血型初、复检不符21例,其中初检错误15例(占71.4%),复检错误6例(占28.6%);不规则抗体阳性19例(检出率为0.25%)。结论输血前血型初、复检和不规则抗体筛查,有利于保障临床输血的安全、及时和有效。

Objective To investigate the clinical value of preliminary testing and re-examination of blood types and irregular antibody screening before blood transfusion. Methods Anticoagulated blood samples from 7751 patients underwent preliminary testing by tube agglutination assay,and were re-examined by micro-column gel immunoassay for blood-typing.Meantime,irregular antibody screening and identification were also performed by micro-column gel immunoassay. Results Twenty one cases were examined for incompatibility with preliminary testing and re-examination on blood types of 7751 patients. Among the 21 cases,15 cases(71. 4%) were inaccurate in preliminary examination and 6 cases(28. 6%) were inaccurate in re-examination. Besides,19 patients with irregular antibody were detected at a rate of 0. 25%. Conclusion Preliminary testing and re-examination of blood types and irregular antibody screening before blood transfusion are necessary and significant tools to guarantee the safety,effectiveness and timeliness of transfusion.
