Faulty Libre 2 Plus sensors?

[Davidden]

I have been using Libre 2 Plus sensors for some time now, with very few problems. About 6 months ago I had to get one replaced as the "probe" bent on application, but other than that they have worked well. Yes, I get frustrated when I get unexpected spikes, but on the whole it has made me a bit more careful with my food intake, and I know what to avoid (or take in moderation!). About a month ago my new sensor started showing extremely low readings - my averages plummeted and I had several "hypos", which I did not believe, and which fingerpricks showed were false readings! I felt fine throughout so put it down to a faulty sensor. The next one fell off the first night! Never had that before, but contacted Abbot for a replacement, and popped on my spare (I get 2 at a time from my pharmacy). That also didn't stick very well so I ordered a pack of adhesive patches from Amazon, and used a sticking plaster till they arrived.
This sensor has been given abnormally high readings! I have hardly been in range since starting it, when I am usually well over 90% in range with out of range readings occasionally after food, and last night it went over 12 shortly after midnight (4 hours since food, which was a pear!) and stayed up there, rising to 14.7 before breakfast! Again, I feel fine, so put this down to another faulty sensor. So wondered what others here have experienced like this? We are supposed to monitor our blood sugars and alter our food intake (and for some of us our insulin intake!) based on these dubious readings. (I have had to resort to using my old fingerprick monitor as the new Contour one has given up the ghost, as well - replaced the batteries and it has remained dead, so am waiting for a replacement for that, too!)
I have my next review this coming Friday, so hopefully the nurse can shed some light on this, but at the moment I have no faith in the Libre 2 Plus!

Hi
Old type 1 here and have had issues with the sensors.
I check my sensor reading ( with a finger prick test) once a day for peace of mind because of the lack of accuracy.
I only do this when i have no fast acting insulin on board and not eaten recently or been on the move physically.
If in doubt always test with a finger prick (assuming you have one).
I was diagnozed in the 1970s when all we could do was test our urine so i don't get phased much but the Libre can test even my patience as when its working properly its magnificent.

I wish you well
Tony

Hello, same here lots of false readings with Libra2 , just a few weeks ago I was bieng woken and alarms in the daytime teling me Bm was as low as 2 but feeling high? and yes Libra 2 was saying 2, 2.5, 3 etc but actual BM was above 10. so i replaced it and then get one that actualy never managed to give anything except the " wait 10 mins then try again message". As you say tony, its still better than the old testube, tablet and urin test! and when its working properly its magnificent. Good luck with your review Davidden. 42YearsLater

Whenever I get a really unusual reading I do test with a fingerprick, and it is usually between 4 and 6 units higher than the CGM (which I have been told is "normal"!), though sometimes a bit lower on really high readings. I woke with the CGM reading 3.2 a few weeks ago, and a fingerprick said 10.7, which I also felt was a bit high after 10 hours since food! As long as I feel OK (well at 73, with arthritis, and after surgery - last time in April this year - for cancer, as well as can be expected, but always happy with my lot!) I never worry too much. A positive attitude is better than any medicine - well, almost!

Here Here, one day soon glucose responsive insulin will be available, although back in 1979 i was told there will proberbly be a cure within 10 years,Im still waiting, but I am sure it is a realistic hope now, keep up the fight!
