Abstract

Objective: To evaluate the major causes of preanalytical errors in medical laboratory of a tertiary care hospital.

Methods: It was a retrospective study in which we analyzed the sample rejection data of hematology and chemical pathology sections from January to December 2018. Number of rejected samples, reason for rejection and type of test ordered on monthly basis were recorded on a platform.

Results: A total of 113,817 samples were received during the study period. Preanalytical errors were found in 1,688 samples, which constitute approximately 1.48% of the total number of samples received.

Conclusion: Our study highlights the magnitude of preanalytical errors in our setup. Preanalytical errors can lead to loss of patient trust in diagnostic services, can dent the laboratory's reputation, and lead to an increase in the overall operating expenses, both for laboratories as well as the hospitals. Compliance with good laboratory practices can significantly reduce the frequency of pre analytical errors.

检验医学分析前阶段的挑战:某三级医院血液样本不合格率。

目的:探讨三级医院医学实验室分析前差错的主要原因。方法:采用回顾性研究方法，分析2018年1 - 12月血液学和化学病理切片的拒收数据。每月在平台上记录拒收样品的数量、拒收原因和订购的测试类型。结果:研究期间共收到样本113817份。在1,688个样品中发现了分析前错误，约占收到样品总数的1.48%。结论:我们的研究突出了我们设置中的分析前误差的大小。分析前错误可能导致患者失去对诊断服务的信任，可能损害实验室的声誉，并导致实验室和医院的总体运营费用增加。遵守良好实验室规范可以显著减少分析前错误的频率。
