The Ambulatory Glucose Profile (AGP) Report shows data measured by continuous glucose monitoring (CGM) in a standardised and visual format, providing a comprehensive overview of the glucose profile for a person with diabetes. 1-3 This gives people with diabetes and their healthcare professionals a better understanding of glucose levels and acts as a tool to support shared decision making. 1-3

Dr. Richard Bergenstal, International Diabetes Center, Minneapolis, explains how to use the AGP to get a quick overview of a person’s glycaemic variability and pinpoint areas for improvement.

The one-page AGP Report is based on glucose levels measured over the course of each day and night.1 The report displayed combines the daily data to show glucose levels over several days or weeks displayed in the context of a typical 24-hour day. Fourteen days of CGM data are generally sufficient to generate a reliable AGP Report.1 Where there is large glucose variability, a longer period of measurement may be useful.

The standardised report has been welcomed by the diabetes community2 and is recommended by the American Diabetes Association (ADA) in the 2021 Standards of Medical Care in Diabetes.4

Example of a one-page AGP Report showing 14-days of CGM data.2

The AGP Report displays core CGM metrics and targets, as well as glucose fluctuations and daily glucose profiles.1,3 Time in Range (TIR), Time Above Range (TAR; the percentage of time spent above 180 mg/dL) and Time Below Range (TBR; the percentage of time spent below 70 mg/dL) are presented as a stacked, colour coded bar chart:

  • TIR is represented in green. According to clinical guidance, most people* with diabetes should spend at least 70% of the day (around 17 hours), in the target glycaemic range of 70 to 180 mg/dL (3.9 to 10 mmol/L).2
  • TBR, indicating hypoglycaemia, is represented in red (low) and dark red (very low). Most people with diabetes* should spend less than 4% of their day (one hour)** below range.2
  • TAR, indicating hyperglycaemia, is represented in yellow (high) and orange (very high). Most people with diabetes* should spend less than 25% of their day (six hours) above range.2

*For older and/or high-risk people with diabetes, the TIR target is lowered to >50% and TBR reduced to <1% at <70 mg/dL (<3.9 mmol/L).2
 **<1% of this time should be spent in the “very low” TBR of <54 mg/dL (3.0 mmol/L).2
<5% of this time should be spent in the “very high” TAR of >250 mg/dL (13.9 mmol/L).2
