I showed the Libre to my diabetic nurse yesterday and followed her advice for applying a new sensor (done while I was there). She admitted she'd never seen one, was very interested, and discussed it in the light of other cgms she had extensive experience of. She was not at all surprised about a few of the issues I've had and was totally adamant that finger pricking is still essential.
Her advice, based on a lot of experience with cgms was 1) put the sensor on my stomach as I have more fat there than on my arm and b) leave it in for 24hrs before activating it. Voila, this sensor is far more accurate than the previous 3. So far.
I am now a guinea pig for both abbott and the local NHS. She was not impressed by the lack of training Abbott are doing for either user or the NHS. In fact she was quite surprised Abbott are running a buy and try trial with no info going out to my local NHS diabetes teams.
Glad to have a sensor back on, particularly as I'm changing my insulin on her recommendations, trying to improve my overnights by reducing levemir.
I should be receiving a second reader shortly, I shall wait for this sensor to get to its last minutes and then see if I can activate it to the new reader. I half suspect that the sensor life is software controlled in the reader, maybe I'll get lucky and get an extra 14 days out of the sensor this way. Depends if the reader writes down to the sensor I guess.
