AGP

The Ambulatory Glucose Profile (AGP) is a licensed, standardized glucose report created by the International Diabetes Center (IDC). AGP provides a standard set of information and graphs relating to your diabetes management and is only one part of understanding your glucose patterns.

Learn more about the report at agpreport.org.

Average Glucose

The average of all the sensor glucose readings from the selected date range.

Coefficient of Variation

The Coefficient of Variation (%CV) is calculated by dividing the glucose Standard Deviation by the mean glucose. %CV is a standardized measure that assesses the magnitude of glucose variability. The larger the %CV, the larger the variability in CGM readings.

Daily Statistics

Daily statistics are calculated values for the individual day of the week over the date range selected. For example, if the date range is 14 days, all the sensor values collected on the two Mondays in that 14-day range are used in the Monday calculations.

Data Collection

It is possible to use both a smartphone and a receiver to provide sensor data.

The smartphone system sends data to the Dexcom server, where that data is made available for reports. To receive this data, the smartphone needs to be connected to the internet and have the Dexcom Mobile CGM app running.

The Dexcom receiver requires connection to a computer to upload the data periodically. If the patient uses a smartphone part of the time and a receiver part of the time, then Dexcom Clarity needs data from both to provide accurate statistics.

Please refer to Uploading Receivers for more details.

Glucose Management Indicator (GMI)

Glucose Management Indicator (GMI) is calculated using average sensor glucose data. GMI can be an indicator of how well glucose levels are managed. GMI will likely differ from A1C.

Hourly Statistics

Hourly statistics are calculated values for the individual hour of the day over the date range selected. For example, if the date range is 7 days, all sensor values collected for each individual hour for each of the 7 days would be used in the calculations.

Insulin Data

Dexcom Clarity displays insulin when you log insulin events on compatible Dexcom CGM apps and receivers, or with Dexcom compatible connected insulin devices. Only known insulin doses will display.

Dexcom Clarity insulin features may not be immediately available and may not be available in all countries.

• Insulin: Displays fast-acting and long-acting doses. Long-acting data may need to be configured in the connected device to display in Clarity.
• Fast-Acting: Average number of fast-acting units taken per day.
• Long-Acting: Average number of long-acting units taken per day.
• Average Total: Average number of fast-acting and long-acting units per day.
• Average Fast-Acting: The average number of fast-acting insulin doses per day in the selected date range.
• Delivery: If available, the types of insulin delivered during the selected date range.

Sensor Usage

Sensor Usage provides a high-level view of Dexcom sensor usage.

• Days with CGM data shows the number of days during the reporting period with at least 50% CGM readings.
• Avg. calibrations per day displays the average number of calibrations per day, entered by the patient, during the reporting period. Only days with at least 50% CGM readings are included. The Dexcom G6 system is approved for use without calibrations or optionally with calibrations, making it possible to have zero average daily calibrations.

Please refer to Data Collection for more details.

Standard Deviation

Shows how much sensor glucose readings rise and fall. This is also known as glycemic variability.

Time in Range

The percentage of time that glucose levels are in low, target, and high ranges. The following are recommended ranges from an international consensus. Dexcom Clarity ranges may be different than Dexcom CGM alerts. Changes made here apply only to Dexcom Clarity.

• Target Range: 70-180 mg/dL or 3.9-10.0 mmol/L
• Very High: Above 250 mg/dL or 13.9 mmol/L
• Very Low: Below 54 mg/dL or 3.0 mmol/L

Uploading Receivers

Dexcom receivers store a limited amount of sensor readings. It is important to regularly upload Dexcom data to Dexcom Clarity to ensure data is not lost. For touchscreen receivers, upload at least every 30 days. For all other receivers, at least every 180 days.

Very Low

Choose 50 mg/dL or 54 mg/dL (2.8 mmol/L or 3.0 mmol/L) as the limit for Very Low displays within Dexcom Clarity reports. Changing this setting does not change the Dexcom CGM settings.
