    Hey,

    I just wanted to share an experience I've had with the freestyle libre this morning which has left me really shaken.

    I woke up at 7:20am as normal, checked my BG through the libre and it said I was 7.7 and steady. Happy days!

    I got out of bed to have a shower and whilst in the shower I started to feel a bit strange. I got out the shower, checked my BG through the libre again and it said I was 7.4, but something still didn't feel right, I thought to check my BG via my finger pricker... 27.9!!! That's a difference of 20 mmol.

    Obviously I injected right away and my levels are now in target range, I've not been very well which explains the high BG. What concerns me is that should I have trusted my libre, I'd have continued my day not knowing how high I was, I would've had breakfast and not injected to correct my high level... I don't want to imagine what could have happened!

    Even now my libre is 5mmol out of range. I was going to take it out but I'm comparing it to my finger pricker each time now to see the differences. I've emailed Abbott and am waiting to hear back.

    Has anyone else had an experience like this?

    I've been using libres on and off for a few months and have found their accuracy to be OK, not great, but this has really damaged my trust in the product!

    Not a Libre user but from reading it does seem it doesn't perform too well at the extreme low and high end of the scale.....

    But that error you had seems like it could be faulty though.....and I expect Abbott will replace it for you.....

    Hi there, call up Abbott and report this, it's faulty so will need replacing, you can generally allow for a small mmol/l difference but this is wildly inaccurate and needs replacing, they will do this.
