Explore the complexities of hemoglobin A1c (HbA1c) testing in this 27-minute webinar presented by Dr. Rongrong Huang, a board-certified clinical chemist and Assistant Professor at Baylor College of Medicine. Examine the critical role of HbA1c testing in diabetes diagnosis and glycemic control monitoring while understanding the challenges and opportunities present in both point-of-care and laboratory settings. Learn about various HbA1c measurement methodologies used in central laboratories and point-of-care environments, including their advantages and limitations. Discover how hemoglobin variants can impact analytical accuracy and clinical interpretation through real-life case studies that demonstrate discrepancies across different testing methods. Compare the clinical utility of laboratory-based versus point-of-care HbA1c testing, with particular focus on rapid turnaround times for diabetes screening and treatment management in outpatient settings. Understand the role of reflex algorithms, automated processes, and data analytics in enhancing testing accuracy and efficiency. Gain insights into the analytical and clinical limitations related to method types and hemoglobin variants, while exploring how pathophysiological and analytical factors can contribute to testing discrepancies. This presentation provides essential knowledge for laboratory professionals, clinicians, and healthcare providers involved in diabetes care and laboratory diagnostics, offering practical guidance for optimizing HbA1c testing strategies to improve patient outcomes and prevent diabetes complications.
