Ambulatory Glucose Profile (AGP) | Read more on TIRhub.com »

The Ambulatory Glucose Profile (AGP) Report shows data measured by continuous glucose monitoring (CGM) in a standardized 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 glycemic 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 standardized report has been welcomed by the diabetes community and is recommended by the International Consensus on Time in Range.²

Example one-page AGP Report

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 10 mmol/L) and Time Below Range (TBR; the percentage of time spent below 3.9 mmol/L) 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 glycemic range of 3.9 to 10 mmol/L.²
TBR, indicating hypoglycemia, 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 hyperglycemia, 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 <3.9 mmol/L.²
† <1% of this time should be spent in the “very low” TBR of <3.0 mmol/L.²
‡ <5% of this time should be spent in the “very high” TAR of >13.9 mmol/L.²
