目的:研究与分析生化标本临床检验异常的原因及检验前质量控制。方法:选取我院2014年7月-2016年6月检验科的生化标本3632份,采用全自动式生化分析仪及配套试剂对相关指标进行检测,并总结生化标本临床检验异常的原因,再据此制定合理的检验前质量控制措施。结果:3632份生化标本中,150份临床检验出现异常,不及格率为4.13%。其中标本量较少是导致临床检验异常的主要原因,占30.00%,与其他因素比较,差异有统计学意义(P<0.05);此外,标本溶血、餐后抽血以及标本放置时间过久等也是导致临床检验异常的常见因素,分别占16.00%、16.67%、17.33%。结论:患者准备不当,人员采集标本不规范,转运中时间把握不佳等均会使生化标志临床检验出现异常,因此采取有效的生化标本检验前质量控制措施对检验结果的准确性有较大影响,可提高标本质量,从而为临床诊断提供可靠依据。
Objective: To study and analyze the causes of abnormal clinical examination of biochemical specimens and the pre-test quality control. Methods: 3632 biochemical samples of our laboratory from July 2014 to June 2016 were selected, relevant indicators were detected by automatic biochemical analyzer and supporting reagents, and the reasons for abnormalities in biochemical samples were summarized. According to This formulates reasonable pre-test quality control measures. Results: Of 3632 biochemical samples, 150 were abnormal in clinical examination, with a failure rate of 4.13%. Among them, the amount of specimens was the main reason leading to abnormality in clinical examination, accounting for 30.00%, which was significantly different from other factors (P <0.05). In addition, hemolysis, postprandial blood sampling and specimen placement were too long It is also a common factor leading to abnormalities in clinical examination, accounting for 16.00%, 16.67% and 17.33% respectively. Conclusion: The improper preparation of patients, the non-standard samples collected by personnel and poor control of transit time will lead to the abnormal clinical signs of biochemical markers. Therefore, the quality control measures before the effective biochemical specimen tests have a great influence on the accuracy of the test results , Can improve the quality of specimens, so as to provide a reliable basis for clinical diagnosis.
