Blood Glucose Time in Range
Blood glucose time in range measures how much of the day glucose stays in healthy bounds—often more informative than a single fasting reading alone.
Blood glucose time in range is the percentage of day your glucose stays between healthy bounds—often roughly 70 to 140 mg/dL for many adults on CGM, though targets vary by clinician. Time in range captures variability and overnight stability better than one fasting reading.
Meals, sleep, stress, and movement all shift the curve.
