Study population: Pediatric and young adult subjects aged 4-30 years with type 1 or type 2 diabetes, who require daily blood glucose monitoring to manage their diabetes. Approximately 35% of the study population will be age 4-12 years of age, and approximately 30% of the study population will be age 18-30 years of age.

Brief summary: This is a prospective, multi-center, non-randomized, single-arm study intended to characterize the safety of the FreeStyle Libre 2 Flash Glucose Monitoring System when used to manage diabetes in pediatric and young adult patient populations.

Detailed description: Approximately 550 pediatric and young adult subjects aged 4-30 years with type 1 or type 2 diabetes, who require daily blood glucose monitoring to manage their diabetes will be enrolled in the study. Subjects and/or their caregivers will utilize he FreeStyle Libre 2 Flash Glucose Monitoring System for managing diabetes for 6 months. Subjects and/or their caregivers will maintain a diary/log book of Adverse Events experienced during the duration of the study. Assessment of Adverse Events will occur via self reporting at each monthly visit and/or phone call.
