Average Daily Risk Range(ADRR)
Definition
A CGM-derived metric that predicts the risk of extreme glucose events by analyzing the daily minimum and maximum glucose values over a multi-day period. ADRR accounts for both hypoglycemic and hyperglycemic risk on a single scale: values below 20 indicate low risk, 20 to 40 indicate moderate risk, and values above 40 indicate high risk of dangerous glucose excursions. ADRR is clinically valuable because it captures the extremes of glucose behavior that averages and standard deviations may mask.
Why “Average Daily Risk Range” Matters for Glucose Monitoring
Understanding average daily risk range is essential for anyone using or evaluating a continuous glucose monitor. This concept directly affects how CGM devices are designed, how glucose data is interpreted, and how clinical decisions about blood sugar management are made. CGM metrics transform thousands of raw glucose readings into actionable numbers that clinicians use to assess glucose control, adjust medications, and set treatment goals.
This term applies broadly across all continuous glucose monitors and is foundational knowledge for interpreting CGM data, whether you are managing diabetes or using a sensor for metabolic wellness.
