检验科血液标本出现误差的原因分析及应对措施

Analysis of the causes and response measures of blood sample errors in inspection department

目的探讨检验科血液标本检测中的常见误差原因及相应的改善措施。方法选取该院2013年1月至2014年12月存在误差的血液标本98例,对误差类型及原因进行调查分析,并提出应对措施。结果所有误差的血液标本中,凝血标本发生率最高,溶血、血液标本量不准者次之;而标本检验误差原因中送检因素占43.9%,为最高,显著高于其他因素,差异有统计学意义(P<0.05),采集因素次之,占34.7%;送检因素造成的误差中,由于送检时间过长引起的误差发生率最高。结论临床血液标本出现误差较为常见,且引起误差的因素是多种多样,因此需在各个环节加以重视,提高操作者临床技能及责任心的同时,加强送检工作,同时严格规范标本检验操作,以提高临床检验质量。

Objective To investigate the common cause of errors and the corresponding improved measures in the examination of blood samples from the clinical laboratory.Methods 98 cases of blood samples were selected from our hospital during January 2013 to December 2014 and put forward countermeasures after analysing the error types and causes.Results In all blood samples with error,the incidence of coagulation was highest,while incidence of hemolysis and blood sample with volume errors were behind it.And in the causes of sample error,inspection factors accounted for 43.9%,which was higher than the other factors（P〈0.05）,that had significant difference.While the acquisition factors was the second which accounted for 34.7%,and in the errors of inspection factors,the incidence of inspection process lesds was highest.Conclusion Errors are common in the clinical blood specimens and the causes of error factor are varied,therefore,we should pay attention to all aspects and improve clinical skills and sense of responsibility at the same time.In addition,the operator should strengthen the inspection work and regulate the specimen inspection operation strictly.
