Understanding your FreeStyle Libre systems data

Once you’ve connected your sensor to your reader, you’ll gain insights into what affects your glucose levels. Here’s some handy information that explains what you’ll see.

Use the data on your reader to see how you’re progressing over time. 

FreeStyle Libre 2 reader showing various different patterns

Monitor trends and patterns from 
your device to see how well you’ve been managing your glucose over time.

  • Glucose trend arrow

    The direction in which glucose is heading.

  • Current glucose reading

    Glucose level from your latest scan.

  • Glucose graph

    Shows how your glucose levels have changed over the last 8 hours.

  • Target range

    Easily identify when you are above or below your target range.

FreeStyle Libre 2 reader showing Time in Target

Track your progress over time to see how much time you’ve spent in or out of range.

  • Target Glucose Range 

    The more time you spend here, the better your A1c.

  • Above Target Glucose Range

    Shows when your glucose was too high so you can pinpoint what may have caused it to spike.

  • Below Target Glucose Range

    Shows when your glucose was too low so you can pinpoint what may have caused it to dip.

You may not always be within your target range, but knowing what it is can help you better understand how food, activities, and medications can impact your glucose.

Why don’t blood glucose and sensor glucose readings match?

Glucose enters the blood first, which is what finger pricks measure32. Then, it enters the interstitial fluid (ISF) found around cells beneath the skin – this is what sensors measure32. Both are accurate but at slightly different points in time.

Think of blood glucose as the engine of a train, and the interstitial fluid or sensor glucose as the caboose32.

Stable glucose levels

When glucose levels are stable, there’s little difference in measurements.

Climbing glucose levels

As glucose levels rise, like they can after a meal, sensor glucose lags behind blood glucose32.

Dropping glucose levels

After medication or exercise, glucose levels may fall with the sensor glucose again lagging behind32.
