What is Time in Range and Why is it Important?

What does "Time in Range" mean?

Time in Range (TIR) indicates how long glucose levels remain within a defined target range, based on continuous glucose monitoring data.

In managing type 1 diabetes, looking at only a single glucose value or average glucose level may not reflect all the variations throughout the day.

The truck brings a different perspective to this picture.

What does the truck tell us?

Thanks to CGM data, glucose:

• Within the target range,

• Above the target range,

• Below the target range

The time spent can be evaluated.

This allows for a more detailed view of how daily glucose management is progressing.

What is the difference between HbA1c and [the other measurement]?

HbA1c provides information about the average glucose level over the long term.

However, an average value doesn't reflect all the ups and downs throughout the day. For example, two people who experience both high and low glucose levels during the day may have a similar average value.

TIR provides additional information on how long glucose levels remain within the target range throughout the day.

Why is time in range important?

TIR helps to see the course of diabetes management in daily life in more detail.

Specifically, evaluating CGM data over time:

• Detecting glucose changes,

• By examining specific periods throughout the day,

• Evaluation of treatment management,

• More comprehensive monitoring of diabetes is needed.

It can contribute.

Are the goals the same for every child?

No. Glucose targets are assessed individually based on the child's age, clinical condition, and treatment plan.

Therefore, it is important to consider TIR values in conjunction with the child's overall diabetes management, rather than interpreting them in isolation.
