AGP in daily clinical practice: a guide for use with the FreeStyle Libre flash glucose monitoring system
As real-time continuous glucose monitoring and flash glucose monitoring systems become more widely prescribed in the daily management of diabetes, it is important that the ambulatory glucose profile (AGP) methodology for reviewing and interpreting trends in glucose control is effectively applied. In this article we look at the essential features of the AGP and provide systematic and practical guidance on how the AGP can be interpreted in daily diabetes care with confidence. Using examples taken from glucose data captured by the FreeStyle Libre flash glucose monitoring system, we show how each aspect of the AGP can be used to understand daily patterns in glucose control for a person with diabetes, including the importance of time in range and adjunct use of individual daily logs. Using these elements collectively, we show how and why treatment adjustments can be made, with the goal of improving glycaemic control and diabetes outcomes.
