Accurate laboratory diagnosis is essential for effective patient care, but the rejection of specimens within laboratories can have serious consequences.
A retrospective cross-sectional study was conducted from September to November 2021 at the University of Gondar Comprehensive Specialized Hospital laboratory. Two years of laboratory data were collected from laboratory log books and analyzed to determine trends in specimen rejection rates and identify potential reasons for those rejections.
We analyzed 114,439 specimens, of which 786 (0.70%) were rejected. The hematology service exhibited the highest rejection rate, at 273 (0.2%). The main reasons for specimen rejection were specimens without requests or requests without specimens (40.2%), poor smear preparation (12.3%), clotted specimens (11.3%), and labeling problems (8.0%).
This study emphasized a significant incidence of specimen rejection, particularly in the hematology laboratory, underscoring the need for immediate implementation of corrective actions and preventive measures. Furthermore, conducting comprehensive larger-scale studies is recommended to deepen our understanding of and investigate the specific factors contributing to specimen rejection in greater detail.
准确的实验室诊断对于有效的患者护理至关重要，但实验室拒收标本可能会产生严重后果。
本研究为 2021 年 9 月至 11 月在贡德尔大学综合专科医院实验室进行的回顾性横断面研究。从实验室日志中收集了两年的实验室数据，以确定标本拒收率的趋势，并确定拒收的潜在原因。
我们分析了 114439 个标本，其中 786 个（0.70%）被拒收。血液科的拒收率最高，为 273 个（0.2%）。标本拒收的主要原因是无申请或无标本的标本（40.2%）、涂片准备不佳（12.3%）、凝血标本（11.3%）和标签问题（8.0%）。
本研究强调了标本拒收的发生率很高，特别是在血液科实验室，这表明需要立即采取纠正措施和预防措施。此外，建议进行全面的大规模研究，以更深入地了解和调查导致标本拒收的具体因素。
