Reading your Glucose

FreeStyle Libre Sensor
& Reader

  • The Sensor Glucose Readings screen appears after you scan your sensor.

  • Your reading includes your current glucose, a glucose trend arrow indicating which way your glucose is going, and a graph of your current and stored glucose readings.


The sensor is continuously measuring your glucose. You get more information than from a Fingerprick test1, which is only a single point in time.

Use all pieces of information—current glucose reading, trend arrow, and glucose history graph—before deciding what to do.

Daily Patterns

  • The graph shows the variability of glucose levels over multiple days to give a quick snapshot of glycemic control.

  • The graph shows the variability of glucose levels over multiple days to give a quick snapshot of glycemic control.

  • The thick black line shows the midpoint of your glucose readings. (Daily Patterns needs at least 5 days of glucose data.)


Time in Target

(Time in Range)

Time in Range or Time in Target, is the percentage of the time that the person spends with his / her glucose levels in the target glucose range.

The graph shows how much percentage of time sensor readings were above, below and within the Target Glucose Range.


Low Glucose Events

The graph shows information about the number of low glucose events measured by your sensor. Low glucose events are recorded when glucose readings are lower than 70mg/dL for longer than 15 minutes.

1. A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycemia or impending hypoglycemia is reported by the system or when symptoms do not match the system readings. For a complete glycemic picture, scan once every 8 hours.
