What time in range means
Time in range is the share of the day your glucose stays inside a target range.
| Zone | mg/dL (mmol/L) | Example | Many adults aim for |
|---|---|---|---|
| Very low | below 54 below 3.0 | 1% | less than 1% |
| Low | 54 to 69 3.0 to 3.8 | 3% | below 70 in total: less than 4% |
| In range | 70 to 180 3.9 to 10.0 | 72% | more than 70% |
| High | 181 to 250 10.1 to 13.9 | 19% | above 180 in total: less than 25% |
| Very high | above 250 above 13.9 | 5% | less than 5% |
How to read it
- A widely used range for adults is 70 to 180 mg/dL (3.9 to 10.0 mmol/L).
- The international consensus suggests, for many adults, more than 70% of the time in range, less than 4% below 70 and less than 25% above 180.
- Targets differ by person, age and pregnancy, so your care team sets yours.
What it cannot tell you
One number cannot show when the highs and lows happen. Look at the typical day next to it.
