Time in Range Explained

Glucose targets for Type 1 Diabetes are moving away from A1c and toward how much time is spent between 70–180mg/dL.

This is called Time in Range (TIR) and is calculated from CGM or fingerstick blood glucose (if more than 4/day).


TIR gives a better picture of how often you have high and low glucose levels.

The American Diabetes Association (ADA) goals for most people with diabetes is a Time in Range of 70%, which correlates to an A1c of around 7. 


Try setting personal goals to increase your Time in Range, which can improve your lifelong health with diabetes!
