  • Current reading of your glucose levels2,3

  • Glucose trend arrow that helps you see if your glucose levels are normal, on the rise, or dropping2

  • Graph showing 8 hours of glucose history2

Get insights about your glucose levels without fingersticks‡§

Trend arrows help you see the direction and the speed that your glucose levels are changing—giving you the opportunity to make more informed treatment decisions.

Continuous glucose monitoring (CGM) measures interstitial fluid glucose not blood glucose

CGM sensor readings are taken from interstitial fluid, a thin layer of fluid that surrounds the tissue cells below your skin. As carbohydrates are digested, glucose enters your bloodstream before it is absorbed into the interstitial fluid. This is why testing your blood glucose may result in a different reading than a scan of interstitial fluid. Eventually, sensor readings catch up to blood glucose readings giving you a more holistic look at your levels, rather than only capturing one moment in time.

and blood glucose

Removing and replacing your sensor

  • The sensor is designed to stay on for up to 14 days. Your appII¶# or reader will alert you when it’s time to remove. Pull up the adhesive edge that keeps the sensor attached to your skin, then slowly peel from your skin in a single motion.

  • When replacing your sensor remember to choose a different spot on the back of your upper arm to apply the new sensor. This will help avoid skin irritation.

  • Some products** that can be helpful for removal, but are optional:

    • Baby Oil: Soft moisturizer 
    • Remove™ Adhesive: Removes adhesive residue on the skin 
    • UNI-SOLVE™ Adhesive Remover: Formulated to reduce adhesive trauma to the skin by thoroughly dissolving dressing
