Trial Parameters
Brief Summary
The investigators will measure blood levels of 1,5-anhydroglucitol in children with type 1 diabetes and correlate them with parameters related to functional beta-cell mass in diabetic patients. The values will be compared to those obtained in healthy volunteers. Children with newly diagnosed diabetes as well as children with longstanding disease will be included. The aim of the study is to test the validity of 1,5-anhydroglucitol as a novel biomarker of beta-cell mass and function in type 1 diabetes.
