Diabetes is a chronic metabolic disease, and blood glucose monitoring is crucial for its management. Glycated albumin (GA) is a product of non-enzymatic glycation of glucose with human serum albumin (HSA) in the blood and can reflect the average blood glucose levels over the past 2-3 weeks. It compensates for the limitations of glycated hemoglobin (HbA₁c) in short-term blood glucose monitoring and in special populations such as those with hemoglobin disorders. However, there are various methods for detecting GA, including chemical colorimetry, boronate affinity chromatography, immunoassays, enzymatic methods, and mass spectrometry. Traditional detection methods have been replaced by enzyme‑based kits on fully automated biochemical analyzers due to poor traceability and complex operation. Enzymatic methods have become the most widely used approach for clinical GA detection.However, the lack of standardized reference measurement procedures leads to significant variations in detection results among different enzymatic assay kits, making the standardization of GA detection particularly critical. This review summarizes the early detection methods, clinically common enzymatic assays, and standardized liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods to elaborate on the development of GA detection methods. Further analyzes the current status and existing challenges of GA detection standardization, aiming to improve the consistency of results among different detection methods and promote the advancement of GA detection standardization.
