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 Ambulatory Glucose Profile (AGP) is an internationally recognised way of summarising and visualising large amounts of glycaemic data in a clinically meaningful format.1 It 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.
Each of these elements tells a clear story about your patients’ glucose control and variability over a selected time period.
The median line traces the mid-point glucose reading as a measure of average glucose at each point in the modal day and shows whether the average glucose is within the target glucose range and how much it oscillates during the day.2 The goal for the Median Line is for it to be as flat as possible over the entire 24 hours period and within the target glucose range.
The 25th to 75th Percentile band illustrates when glucose variation is common from one day to the next. The band represents 50% of all glucose readings for the patient at each time point. The goal is reduce the more-common day-to-day glucose variability by reducing the width of the 25th to 75th Percentile above and below the median line.
The visible part of the 5th to 95th percentile includes the readings that reflect less common departures from the daily average glucose. Large excursions above or below the Median Line may indicate poor control for a variety of reasons, but if the 5th to 95th percentile band is wide it means that occasionally your patient's glucose control has varied quite a lot from day to day. The goal is to understand if more extreme glucose readings can be linked to occasional activities that a patient can plan for.
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
✓ Detect daily glucose variabilities that can not be displayed by HbA1c.
✓ Assessing a patient's glucose levels versus target range.
✓ Understanding extent and causes of high glucose variability.
✓ Assessing suitability of treatment.
✓ Assessing whether there is a need to adapt insulin doses.
✓ Is useful for helping patients understand their glycaemic control.
✓ Is useful for helping a patient's overall understanding of their diabetes.
