Blood Glucose Monitoring and Time in Range1 

In 2021, Diabetes Canada updated their Clinical Practice Guidelines on blood glucose monitoring to include Time in Range (TIR). In response to the rapid uptake of these technologies among people with diabetes, these guidelines provide recommendations for healthcare professionals who want to use continuous glucose monitoring (CGM) in their practice.

For most adults with type 1 and type 2 diabetes, Diabetes Canada includes CGM metrics and targets that are mirrored in the International Consensus Report. See the full Clinical Practice Guidelines chapter, linked below, for recommended targets for children, adolescents, older adults, high-risk groups, and pregnancy.
