Glycated albumin levels are higher relative to HbA1c levels in people with autoimmune acute-onset type 1 diabetes mellitus than in people with type 2 diabetes mellitus at the time of diagnosis.

Glycated albumin (GA) is a new glycemic control indicator. GA/HbA1c ratio in autoimmune acute-onset type 1 diabetes mellitus patients was significantly higher than in type 2 diabetes mellitus patients at the time of diagnosis. This difference might reflect speed of increase in plasma glucose after the onset of diabetes.
