Understanding Sensor Readings - App


Note: The glucose graph in the App will scale to 500 mg/dL to accommodate glucose readings above 350 mg/dL.

Note: The symbol may appear, indicating the smartphone's time was changed. Gaps in the graph may result or glucose readings may be hidden.



Note: Your current glucose value determines the background color on the My Glucose screen:

High glucose (above 240 mg/dL)

Between the Target Glucose Range and high or low glucose level

Within the Target Glucose Range

Low glucose (below 70 mg/dL)



The Glucose Trend Arrow gives an indication of the direction your glucose is going.

Note: The Glucose Trend Arrow may not always appear with your reading. When there is no Glucose Trend Arrow, you will see a symbol, telling you to do a blood glucose test before making treatment decisions.

Glucose is changing slowly (less than 1 mg/dL per minute)
Glucose is falling (between 1 and 2 mg/dL per minute)
Glucose is falling quickly (more than 2 mg/dL per minute)

If your glucose is projected to be higher than 240 mg/dL or lower than 70 mg/dL within 15 minutes, you will see a or a message on the screen. You can touch the symbol for more information and set a reminder to check your glucose.
