The Abbott FreeStyle Libre has come as an entirely new concept in glucose monitoring by providing much greater data than blood glucose testing whilst being more affordable Continuous Glucose Monitors(CGM).
How the FreeStyle Libre works
The FreeStyle Libre works by having a small round sensor applied to your arm. The sensor is a round disc, 5mm high and 35mm diameter. Its easy to operate .
Are glucose readings different between CGM and BGM?
Instead of taking glucose readings from your blood, CGM sensor glucose readings are taken from the interstitial fluid (ISF), a thin layer of fluid that surrounds the cells of the tissues below your skin. Blood glucose readings tend to be about 5 to 10 minutes ahead of interstitial glucose readings. For most treatment decisions, sensor readings from the FreeStyle Libre 14 day system can replace fingerstick readings.*
* Fingersticks are required for treatment decisions when you see Check Blood Glucose symbol, when symptoms do not match system readings, when you suspect readings may be inaccurate, or when you experience symptoms that may be due to high or low blood glucose.
