Abstract

Quality control (QC) and quality assurance (QA) are critical components in maintaining the accuracy, reliability, and timeliness of results in medical laboratories. Inaccuracies in laboratory diagnostics can have significant clinical repercussions, affecting patient treatment and outcomes. This paper delves into the fundamental principles of QC and QA, their methodologies, and the implementation of standardized processes to optimize laboratory performance. Furthermore, it highlights the importance of international standards such as ISO 15189 and the necessity for continuous improvement strategies in laboratory practices. This study also discusses how advancements in technology, automation, and artificial intelligence are shaping the future of laboratory quality management.
