THE ROLE OF LABORATORY PROFESSIONALS IN IMPROVING DIAGNOSTIC ACCURACY

Abstract

Laboratory medicine plays a fundamental role in modern healthcare, with diagnostic testing influencing approximately 70% of medical decisions. Despite technological advancements, diagnostic errors continue to present significant challenges to patient safety and healthcare quality. This study examines the critical role of laboratory professionals in enhancing diagnostic accuracy across the total testing process (TTP), encompassing pre-analytical, analytical, and post-analytical phases. Laboratory professionals contribute specialized expertise in test selection, specimen handling, quality control, result interpretation, and collaborative communication with clinicians. The integration of innovative technologies such as automation, artificial intelligence, and molecular diagnostics has revolutionized laboratory operations, improving efficiency and reducing error rates. However, several challenges persist, including pre-analytical variability, test utilization issues, interpretation errors, and workforce shortages. Strategies to improve diagnostic accuracy include establishing diagnostic management teams, implementing quality indicators, utilizing decision support systems, and enhancing professional education. Through these efforts, laboratory professionals can significantly contribute to diagnostic excellence, ultimately improving patient outcomes and healthcare system performance.
