Preanalytical Errors in Clinical Biochemistry: A Focused Review of Current Challenges and Solutions

Dr. Mohamed Amri

Abstract: The preanalytical phase is a critical yet often overlooked component of clinical biochemistry diagnostics. Studies (1,2) indicate that 60% to 70% of laboratory errors occur before sample analysis. This review synthesizes findings from 29 publications published between 2020 and 2025, focusing on common sources of preanalytical errors such as sample collection, transport, storage, and identification. These errors can lead to misdiagnoses and inappropriate treatments, posing substantial risks to patient safety. Proposed solutions include standardized training, automation, and robust quality control systems. Integrating these measures is essential for improving laboratory reliability and ensuring accurate diagnostic outcomes.
