Understanding Sensor Readings - App
Note: The glucose graph in the App will scale to 400 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.

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 tap the
symbol for more information and set a reminder to check your glucose.
- If you are not sure about a message or reading, contact your health care professional before you do anything.

If LO appears, your reading is lower than 40 mg/dL.
If HI appears, your reading is higher than 400 mg/dL.
You can tap the symbol for more information. Check your blood glucose on your finger with a test strip. If you get a second LO or HI result after doing a blood glucose test, contact your health care professional immediately.
