        abstract = {Quality control (QC) is a cornerstone of reliable laboratory diagnostics, directly influencing patient care, clinical decision-making, and healthcare outcomes. Despite advances in automation and standardization, clinical laboratories continue to face quality control errors that compromise test accuracy and reliability. These errors may arise during pre-analytical, analytical, or post-analytical phases and can result from human factors, instrument malfunction, reagent variability, environmental conditions, or inadequate quality management systems. This review provides a comprehensive analysis of quality control errors in clinical laboratories, including their classification, root causes, and clinical impact. Current quality control practices, statistical tools, and regulatory guidelines are discussed, along with emerging approaches such as risk-based QC, sigma metrics, automation, and digital quality management systems. Strategies for error prevention and continuous quality improvement are highlighted to enhance laboratory performance and patient safety.},
