Background: Clinical laboratories are essential healthcare facilities that play a vital role in diagnosing, treating, and managing patients. They provide valuable information to clinicians through laboratory tests on biological specimens. These tests are crucial for medical decisions, accounting for 60%-70% of such decisions. With advancements in laboratory medicine over the past few decades, laboratories can now measure substances at picomole concentrations and analyze genetic material. Automation and technological progress have transformed laboratory operations, requiring staff to be proficient in complex analytical methodologies and equipment. The preanalytical phase, analytical methodology, and pathophysiology knowledge are crucial for accurate testing and result interpretation. Objective: This review aims to assess the current role and impact of clinical laboratories within the healthcare system, identify challenges faced by these facilities, evaluate collaboration with other healthcare providers, explore strategies for improving efficiency, and emphasize the importance of supporting clinical laboratories. The significance of clinical laboratories lies in their contribution to medical diagnoses, treatment monitoring, patient safety, disease surveillance, and outbreak detection. Conclusion: Clinical laboratories face challenges such as increasing demand, resource constraints, regulatory requirements, and evolving technologies. The competence of laboratory staff, including technicians and diagnosticians, is crucial for delivering accurate and timely results. Errors in clinical laboratories can have serious consequences on patient care, highlighting the importance of quality control measures and continuous improvement efforts. Investing in and supporting clinical laboratories is vital for enhancing healthcare quality, improving patient outcomes, and ultimately saving lives.
