摘要
目的探讨导致血常规检验结果出现误差的原因。方法120例接受血常规检验的受检者,采集其静脉血以及末梢血作为研究所用血液样本,然后对已有样本进行冷藏以及常温存放处理。分析血常规检验结果出现误差的原因,并比较不同存放时间的血液样本的检测结果。结果120份血液样本当中,有29份血液样本最终检测结果同患者的实际病情存在明显误差,误差率为24.2%。其中导致血液样本检测结果发生误差的原因主要有患者自身因素、血液样本采集时间不科学、血液样本存放不当、血液样本送检时间过长以及抗凝剂浓度不符合要求等。存放即刻、2 h、6 h、12 h的血液样本中白细胞、红细胞、血小板、血红蛋白水平比较,差异有统计学意义(P<0.05)。结论血常规检验期间,患者自身因素、血液样本采集时间不科学、血液样本存放不当、血液样本送检时间过长以及抗凝剂浓度不符合要求等多种因素均会对检验结果造成影响,进而出现一定的误差,因此需要对血常规检验过程中的各个环节加强监控,避免因各种素使检测结果出现误差,从而使检验结果准确性提升。
Objective To discuss the causes of errors in blood routine test results.Methods Venous blood and peripheral blood were collected from 120 subjects who underwent blood routine tests,and then the samples were refrigerated and stored at room temperature.The causes of errors in the results of blood routine tests were analyzed,and the test results of blood samples at different storage times were compared.Results Among the 120 blood samples,29 blood samples had significant errors between the final test results and the actual condition of the patients,with an error rate of 24.2%.The main causes of errors in blood sample test results include patients’own factors,unscientific blood sample collection time,improper storage of blood samples,long delivery time of blood samples and non-compliance of anticoagulant concentration.The levels of white blood cells,red blood cells,platelets,and hemoglobin of blood samples stored immediately,2 h,6 h,and 12 h showed statistically significant differences(P<0.05).Conclusion During blood routine tests,various factors such as patients’own factors,unscientific blood sample collection time,improper storage of blood samples,long delivery time of blood samples and non-compliance of anticoagulant concentration can affect the test results and lead to certain errors.So it is necessary to strengthen the monitoring of various aspects of each link in the blood routine test process to avoid errors in the test results due to various factors,thereby improving the accuracy of the test results.
