Ambulatory Glucose Profile

Ambulatory Glucose Profile (AGP) can be used to review glycaemic control with each of your patients and can help you focus on aspects of their glycaemic control to support their daily diabetes management.

There are four key components of an AGP:

  • Median
  • 25th–75th Percentile
  • 5th–95th Percentile
  • Target Glucose Range

Each of these elements tells a clear story about your patients’ glucose control and variability over a selected time period.


The ‘average’ (middle) point of all glucose levels that shows ‘what usually happens’ during a day.2 Look at whether it is in the target glucose range and how much it swings up and down throughout the day.

INNER BLUE-SHADED BAND: 25th to 75th Percentile

This band indicates where glucose levels are ‘half the time’. Look at width of the band throughout the day. The wider this band is, the more variable the glucose levels are day-to-day.2

OUTER GREY-SHADED BAND: 5th to 95th Percentile

This band indicates more ‘occasional’ high or low glucose levels. Look at areas where the band is widest, this indicates more day-to-day variation at these times.2

TWO PARALLEL LINES: Target Glucose Range

This is the corridor where glucose levels should be as much as possible. According to international consensus, the target glucose range is usually 3.9 mmol/L–10 mmol/L for adults with type 1 and type 2 diabetes who are not pregnant, not older, or at risk.1

The benefits of reviewing AGP

The benefits of reviewing an AGP during a diabetes clinical review

✓ AGP is a visually impactful way to quickly identify times of greater risk of hypoglycaemia or unwanted glucose variability.2

✓ The visual format of the AGP allows the eye to quickly focus on areas that may need review and these can be assessed in terms of how significant they are by their timing, duration and how low glucose has fallen.2

✓ You can use the elements of the AGP in a systematic and straightforward way to help identify trends in glucose control. This includes not only the areas that may require remedial action, but also the parts of each day that reveal when glucose is in range and you are able to reinforce and encourage behaviour choices.2
