Hi all,
My wife's LibreFree just notified her of low sugar after waking up from a nap (last meal intake over 2 h ago). I tested and returned 3.3mmol then after 5 min 3.1mmol. I found it unusual so I decided to do a finger test as we are at home. To my surprise, the finder reads 7.0mmol!!
The gap is really big and really brings doubts to me if I can really trust LibreFree. So far we have been using it as our main reference, and on some occasions where we have tested finger blood to check reliability, the difference has been ~15% between the two reads. However, a difference of almost 4mmol really worries me and it makes me think when she is 7mmol in the morning spike, is she really 7, or could be an 11mmol reported incorrectly?
I will start comparing with finger reads more often but I would like to know if anyone has had this experience before and also what was Libre support response (planning on contacting them)
To add, my wife is currently starting her period and I believe sugar reads always are more "extreme" and change drastically in such times (would also be great to get people opinions on this)
5 minutes after, Libre is reading 4.8mmol, now 5.5mmol, I find this very misleading and I find it hard to trust the device and the readings, please some help to understand such situation
Thank you,
Adrian
