Unreliable Libre2s

Over the last 8 sensors I've had 3 that were uncannily accurate, 1 that was close but not that close, 3 that have died and the most recent one that I'm confident will be dead by the morning, it's been reading between 2.8 and 3 since application and is currently reading 3 while the finger prick said 7.6.

This is more than useless. Do those of you using 2+s have better results? As I'm getting such useless and possibly damaging info I'm seriously thinking of just giving up on them.

I guess because it's been discussed a lot. See https://forum.diabetes.org.uk/boards/threads/cgm-limitations-and-precautions.108188/ for a general thread.

Some people find they get on better with Dexcom One+ (if Libre 2 Plus doesn't work well) and some people find the opposite. Some people find they get a string of sensors that fail (perhaps because a batch has some fault, or perhaps just coincidence). I think most of us get a sensor now and again that doesn't work right (usually just sticking at some low values).

Report to abbot and replace them. Or go back to fingerpricking or a different sensor if preferred. It’s all personal to you, other people’s accuracy experiences on libre make no difference to your experience because accuracy is individual to the person and details of their body
 
I have used the original Libre, Libre 2, 2+ and now 3. I have had faulty and inaccurate sensors with all of them. I find the first 24 hours are often very inaccurate and for this reason, I apply my new sensor the day before my current one runs out to give it a day to 'settle in'. This seems to have helped with a lot of the problems I was having before. I did have a run of bad sensors, I don't know if it was a faulty batch or just coincidence but my pharmacist said that they had heard lots of people were struggling with them at that point (this was a few years ago). Do contact Abbott, either by phone or using their online form to report the sensors and they will send you replacements.

If your sensor is consistently reading low, when you remove the sensor check whether it has actually gone under the skin properly. If it's kinked or folded then it didn't go in properly. I had a lot of problems with this with Libre 2 and 2+ and found that it was best not to apply a new sensor after a bath or shower or when I was very warm, I don't know why but my skin seems to be less easy to break through! I also struggle to insert new cannulas or inject when my skin is too warm! I've never heard anyone else having this problem though so it might just be me.

There are other brands of sensors that you can try if you don't get on with Libre but there will always be a bit of error I think.
 
In 5 years of using all libres I hand maybe 2 inaccurate sensors, hence not commenting.

Around 3 that either didn't stick, or fell off, 1 that bent as it went on and a few that just didn't work, but all as soon as they went on or in a very quick period of time. I found them to be very good quality, every now and then there seems to be a bad batch but no product is perfect.

I had no issues until I moved onto the Ominpod 5 and then libre 2+ just wouldn't connect to the PDM, it connected with my phone app fine, only the PDM / Omnipod 5s it didn't like. I am not even sure this is the fault of the libre's.

I do know from my DSN that some peoples bodies just do not work with certain CGM's or with any at all.

I have had more issues with the Dexcom 6 in the 4-5 months than I had in nearly 5 years if libre.

The 24 hours is a thing for some users, wasn't for me.

Report the faults, abbot are good at replacing.

Ask your team / GP if you can try another.
 
Mine are usually extremely accurate and I have been using them since shortly after they came out (i.e. Libre 1). I think I've probably had more duff 2+ ones than previous ones. I'm now on Libre 3+ since 1 May and in that time have had one that just wouldn't start, but on the whole they've been very good.
 
One of the reasons I used xDrip+ rather than LibreLink app was because I was able to calibrate the sensors to my body.
They were consistently out if I didn't.
I have not used Libre 2+ so do not know if they have improved.
