TABLE 1.

Targets for CGM Metrics

CGM Metric Target, %
TIR (70–180 mg/dL) >70
Time >180 mg/dL <25
Time >250 mg/dL <5
Time <70 mg/dL <4
Time <54 mg/dL <1

Targets may differ for 1) older adults with diabetes or those considered at high risk for hypoglycemia, for whom a lower target may be the goal, and 2) pregnant women with diabetes, for whom the target may be 70% of values between 63 and 140 mg/dL.
