HbA1c testing plays an important role in diabetes screening, diagnosis, and long-term glycemic management. Unlike a blood glucose test, which provides a snapshot of glucose concentration at a specific point in time, HbA1c reflects the body's exposure to glucose over a longer period. High-Performance Liquid Chromatography (HPLC) is one of the established analytical technologies used for HbA1c measurement. By separating different hemoglobin fractions before quantification, HPLC can provide both a numerical HbA1c result and a chromatographic profile of hemoglobin components. In this article, we explain the principle, testing workflow, chromatogram, calculation, advantages, and limitations of HPLC HbA1c testing.

Hemoglobinopathies (including β-thalassemia and structural hemoglobin variants) and diabetes mellitus are two major global health burdens that frequently coexist in high-prevalence regions. This coexistence presents significant analytical challenges for glycated hemoglobin (HbA1c) measurement and interpretation. High-Performance Liquid Chromatography (HPLC) has emerged as a robust analytical platform capable of simultaneously supporting HbA1c quantification and hemoglobin variant detection.

Hemoglobin A1c (HbA1c) testing plays a critical role in the diagnosis and long-term management of diabetes. As clinical decisions increasingly rely on precise and standardized results, the choice of testing methodology becomes more important than ever. Among the most widely used technologies, Immunoassay, Boronate Affinity, and High-Performance Liquid Chromatography (HPLC) each offer distinct advantages and limitations. Understanding these differences is essential for laboratories aiming to balance efficiency, accuracy, and clinical reliability.

The A1C test—also known as HbA1c, glycated hemoglobin, or glycosylated hemoglobin—is a simple blood test that reflects your average blood glucose level over the past three months. It is one of the most important tools for screening, diagnosing, and monitoring diabetes and prediabetes. Our range of analyzers offers multiple technologies for HbA1c testing: 1️⃣ FiCA Immunofluorescence Analyzer – enabling rapid HbA1c testing in point-of-care settings. 2️⃣ UClia POCT CLIA Analyzer – combining high sensitivity and convenience for on-site HbA1c analysis. 3️⃣ M3 HPLC HbA1c Analyzer – providing gold-standard precision for laboratory-level HbA1c measurement. 显示译文
