    Anyone else experiencing a bit of issues when it comes to hypos with the libre 2?
    I get false alarms sometimes where it will alarm, I’ll scan and it’ll say my sugar is 4.4 when my alarm barrier is set to 4.2. then once I’ve treated a hypo the sensor will instantly lose signal for half hour or so or continue to send low alarms although a quick finger prick will say the hypos been treated. Even with the delay taken into consideration. Anyone else experiencing similar issues when it comes to hypos? It’s great any other time.. not sure if perhaps it’s an issue with the sensor itself.

    Hi,

    I do find the Libre 2 (like the 1.) slow to reflect a rise from a low with any graph interpretation on whateverr app I use.
    Now dropping, I find the Libre 2 will alarm on the Diabox app I'm currently using a good 5 minutes before I feel low?
    The first time I thought when the already kicked off "am I hell.?" Then after a few minutes, "hello?"
    I've set a snooze time of half an hour after I've treated, but it can still kick off after the meter confirmed how I feel..
    Once the Libre2 falls back in line with me, I find it reasonably stable.

    So I wouldn't disagree with your experience using the set up you have...

    Oops edited to add; seeing as the sensor interprets BGs through measuring interstitial fluid? Possibly it the last thing to respond from a low while the brain takes a priority.. I know my brain & eyes waves the white flag first whilst the BGs sink..

    I find that when the alarm goes off (either high or low) I’m usually 1 mmol the right side of it’s reading. Saturday I was getting low alarms at 4 but was actually 5 so I just waited 15 mins to see which way I went.

    I only really trust finger pricks for correcting lows & highs, using the sensor for all the times in between.
