Abstract

Background: Clinical laboratories have a crucial role in the diagnosis, monitoring, and treatment of diseases. The total testing procedure is significantly affected by the preanalytical factors. In this study, we aimed to assess pre-analytical errors to ensure high-quality laboratory performance.

Methods: A one-year retrospective data analysis from the Laboratory Information System was conducted, focusing on the sample rejections for the year 2023 from the central laboratory of our hospital. The data is evaluated based on the samples sent from various departments and by the analytic groups studied from these samples.

Results: The total number of samples admitted to the central laboratory of the Ankara Bilkent City Hospital were 2,647,527 in year 2023. Out of this total number, 35,024 samples (1.32%) were rejected. Among these rejections, 29,699 samples (84.8%) were rejected due to preanalytical causes. The most encountered preanalytical rejection reasons were improper test request, inadequate sample volume, and incomplete/incorrect information in the test request. The biochemistry samples had the highest rejection rates in the main, cardiovascular, oncology, obstetrics & gynecology, and physical therapy & rehabilitation departments. The coagulation samples were mostly rejected in the neurology and orthopedics departments, and the hemogram samples had the highest rejection rates in the pediatrics department.

Conclusions: The preanalytical phase of the total testing procedure is the stage most vulnerable to errors. Therefore, it is crucial to focus on identifying preanalytical errors and implementing corrective actions, as this will enhance the accuracy and quality of the test results.

安卡拉比尔肯特市医院中心实验室分析前错误率。

背景：临床实验室在疾病的诊断、监测和治疗中起着至关重要的作用。总的测试过程受到分析前因素的显著影响。在本研究中，我们旨在评估分析前误差，以确保高质量的实验室性能。方法：回顾性分析实验室信息系统1年的数据，重点分析我院中心实验室2023年度的拒收样本。这些数据是根据来自各个部门的样本和分析小组对这些样本进行评估的。结果：2023年安卡拉比尔肯特市医院中心实验室收治的样本总数为2,647,527例。在总数中，35,024个样本（1.32%）被拒绝。其中，29699份（84.8%）样品因分析前原因被拒绝。最常见的分析前拒收原因是不适当的测试请求、样品量不足和测试请求中的信息不完整/不正确。生物化学样本排斥率最高的科室为内科、心血管科、肿瘤科、妇产科、理疗康复科。凝血标本拒绝率以神经内科和骨科居多，血象标本拒绝率以儿科最高。结论：整个检测程序的分析前阶段是最容易出错的阶段。因此，重点识别分析前错误并实施纠正措施是至关重要的，因为这将提高测试结果的准确性和质量。
