Targets for assessment of glycemic control: Type 1 / Type 2 and Older/High-Risk Individuals [74]

Diabetes Group	Time in Range (TIR)		Time Below Range (TBR)		Time Above Range (TAR)
Diabetes Group	Within Target Range	% of readings time/day	Below Target Level	% of readings time/day	Above Target Level	% of readings time/day
Type 1^* / Type 2	70–180 mg/dL 3.9–10 mmol/L	>70% >16hr, 48 min	<70 mg/dL <3.9 mmol/L	<4% <1 hr	>180 mg/dL >10 mmol/L	<25% <6 hr
Type 1^* / Type 2	70–180 mg/dL 3.9–10 mmol/L	>70% >16hr, 48 min	<54 mg/dL <3.0 mmol/L	<1% <15 min	>250 mg/dL >13.9 mmol/L	<5% <1 hr, 12 min

Older/High-Risk	70–180 mg/dL	>50%	<70 mg/dL	<1%	>250 mg/dL	<10%
Type 1 / Type 2	3.9–10 mmol/L	>12 hr	<3.9 mmol/L	<15 min	>13.9 mmol/L	<2 hr, 24 min

For age <25 yr., if the A1C goal is 7.5% then set TIR target to approximately 60%.
