How Does Freestyle Libre 2 Measure Glucose

The Freestyle Libre2 CGM estimates your sugar levels and sends this info wirelessly to a program on your phone or insulin pump. This program figures out how much insulin your body needs. When your sugar levels get too high, the pump delivers the insulin to bring them back within your target does work freestyle libre 2 ashcroftpharmacy .uk
When you put the Freestyle Libre 2 sensor, a tiny filament goes under your skin to measure glucose levels. The sensor tracks glucose levels in the interstitial fluid (ISF), a fluid surrounding the cells beneath your skin. It focuses on ISF glucose rather than blood glucose.


  • Trend Clues: The trend arrow shows you where your glucose levels are heading.

  • Be Patient: Allow a little time for glucose to shift from blood to the ISF (interstitial fluid).

  • Time Difference: Sensor readings are typically around 2 minutes behind blood glucose readings.

  • Substitute with Confidence: For many decisions, Freestyle Libre 2 system sensor readings can replace routine finger-prick tests.

Stay empowered with these insights for smoother glucose monitoring!
