Libre - Findings and queries

[berryr99]

I am having a very positive experience with Libre - on week 6 now.
Having been worried about the sensor sticking, the opposite is true - they stick too well !
Now I can see what is going on my time in range is increasing and I have stopped snacking "just in case" and have become braver with the amount of insulin taken
Query: the range is set at 3.8 to 10. Does anyone know why these figures are used - I'm guessing they may be "libre" range and not BS range - as Libre and BS don't measure the same substance.
I know to fingerstick for "odd" Libre readings but have got into the bad (?) habit of cross checking every Libre reading. How to get away from this ?

From my records I know that Libre is always over to a fingerstick test but not hugely so unless readings are very high or very low so probably need a bit of guidance on how to go forwards

Getting excellent GP support from the practice nurse who seems very switched on to Libre.

3.9 to 10.0 is the accepted thing to use. (And while Libre isn't measuring blood glucose, the numbers it's reporting are for blood glucose.)

Hi Robert. Glad your finding it a positive experience and hope that as your confidence in it grows, you'll need to finger prick less. I hardly ever finger orick now, only when my low glucose alarm goes off or I'm getting strange readings from a new sensor as sometimes a new sensor can give a false alarm when first applied. Comparative readings can be almost the same or a bit different as sensor measures interstitial fluid rather than blood so can lag behind a wee bit, but not enough to worry about. That's what ,I've found anyway. At first I was checking it all the time as it was quite a learning curve and it helped me to see what different foods did to BG. I love my sensor and can't imagine how people managed before. I'm much more relaxed now and don't watch it all the time. Good luck with it all .
