Core Tip

Core Tip: This is the first systematic review and meta-analysis investigating the utility of glycated albumin (GA) for the diagnosis of diabetes mellitus (DM). Three studies regarding gestational diabetes mellitus (GDM) were included in the systematic review, and another 16 studies on non-GDM were included in the meta-analysis. This study found that the average cut-off values of GA reported for GDM diagnosis were much lower than those for non-GDM. The GA cut-off value of 14.0% exhibited a moderate diagnostic accuracy in non-GDM. GA, as the sole DM diagnostic test, should be interpreted with caution to assure the correct classification of diabetic individuals.
