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).
The FreeStyle Libre provides ‘flash glucose monitoring’ with glucose readings provided by scanning a sensor rather than pricking your finger. You can order your FreeStyle Libre sensor now
Due to way the Libre works, there are a number of benefits:
Your sensor glucose (SG) readings are taken from your interstitial fluid, and not from your blood, like fingersticks. Interstitial fluid is the fluid that surrounds the cells of your tissue below your skin, and usually glucose moves from your blood vessels and capillaries first and then into your interstitial fluid. It’s helpful to think about it like a rollercoaster where the front car is the blood glucose (BG) and the car in the back is the sensor glucose (SG):

When on the rise, the BG value is greater than the SG that follows behind it. But when moving down the tracks, the BG in front is now less than the SG value.
A few points to remember when using CGM
Here’s A Tip: Knowing the direction and speed of your glucose changes will be more useful than focusing on individual BG or sensor readings. When using continuous glucose monitoring (CGM) trends are the key. In fact, seeing trends and patters in your glucose is likely one of the primary reasons you started using CGM therapy. Trends highlight the direction that your sensor glucose readings are moving and the speed at which they are changing. Fingerstick blood glucose readings and sensor glucose readings are only snapshots of your glucose at that very moment. Trends can tell you if your glucose has been rising, falling, or appears to have been stable over several minutes, hours, and even the day.
So it’s important not to focus too much on the individual sensor glucose numbers (as it is likely to be different from your BG meter reading) and more on trends and patterns in your glucose levels.
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

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.
