Triglyceride-Glucose Index Versus Glycated Albumin: Diagnostic Tools for Early Detection of Insulin Resistance and Pre-Diabetes

Year: 2025
Type: article
Study design: Observational Study
Abstract: Background: Early detection of insulin resistance is essential for preventing type 2 diabetes and cardiovascular disease. Conventional methods like HOMA-IR rely on insulin assays, which may not be readily available in all clinical settings. This study explores the diagnostic potential of the TriglycerideGlucose (TyG) Index and Glycated Albumin (GA) as accessible, non-insulinbased markers. Methods: A cross-sectional analysis was conducted on 120 adults aged 18–60 years. Anthropometric measurements and fasting blood samples were collected. Insulin resistance was determined using HOMA-IR, with a cut-off value >2.5. ROC analysis was performed to evaluate the predictive ability of TyG and GA, and multivariate regression was used to identify independent predictors. Results: Among the participants, 25% were classified as insulin resistant. The TyG Index showed a significant correlation with HOMA-IR (r = 0.26, p = 0.005), whereas GA did not (r = – 0.12, p = 0.196). ROC analysis revealed a moderate predictive value for TyG (AUC = 0.691), while GA showed poor discrimination (AUC = 0.588). Multivariate analysis identified BMI and TyG as significant independent predictors of insulin resistance, with Glycated albumin contributing minimally. Conclusion: The TyG Index demonstrates promise as a practical, non-insulin-dependent marker for identifying insulin resistance, particularly in resource-limited settings. While Glycated Albumin remains useful for glycemic assessment, it may not reliably indicate insulin resistance in this population.
