My first post, apologies if the answer has been amply covered before.
I started using the FreeStyle Libre 2 in October 2023. It's not perfect but I value the high and low glucose alarms at night.
After several mostly satisfactory months, my current sensor (since six nights ago) initially gave very erratic connection with my phone, including lengthy drop-outs.
After a few days the offline periods ended and the sensor is now recording the level steadily and continuously...but all the results are far below my finger-prick test results, even when there's no rise or fall hour by hour. Now, for instance, the Libre is reading 5.6 while the Accu-Chek Performa and Contour Plus are reading double that. Even my ancient Glucotrend (25 years old) still gives exactly the same results as brand new blood glucose testers, and they're all high above what the Libre sensor is saying.
As a result, if I keep my blood glucose between 5 and 8 according to the BG testers, the Libre records a perpetual hypo (it did for five hours last night). My time in range has dropped from 90s to low 80s in a couple of days.
I recognise that when levels are rising or falling, it takes the Libre time to 'catch up' with readings from blood glucose tests. That is not the problem in this instance - it's more like a calibration issue.
I was assured when being introduced to the Libre that if a sensor failed, I could apply to the manufacturer Abbott for a replacement.
Can anybody link me to the correct site to use to make that request?
Thanks for reading!
