Libre 2 v Libre 1

As a T1 I am lucky enough to be prescribed the Libre FGM from Abbott. This has been truly life changing for me and I really can't imagine life without it now. Recently I've received notification that Abbott are discontinuing production of the Libre 1 sensor and have migrated onto Libre 2. However I am very disappointed with the Libre 2 because, on numerous occasions, it doesn't give me a reading, telling me to try again in 10 minutes. Sometimes this happens for over an hour before a reading reappears. Whilst this happened very occasionally with the Libre 1 system, the frequency with Libre 2 is becoming very frustrating and actually quite distressing. On a number of occasions I've had to return to finger prick testing which is truly a backwards step.
The time that this sensor failure occurs seems to coincide with times when my blood sugars are changing rapidly. Have other users experienced this and what have you done about it please? For me this is often when I'm playing sport which, from my point of view, is the most important time to understand your blood sugar levels.
Abbott have been pretty useless in responding to my questions. They say that, unless the sensor failure lasts for more than two hours, they wont replace it free of charge. Quite frankly I wasn't asking for a replacement and, by the way, where did this arbitrary two hour limit come from! For me, if I'm playing sport, I cannot afford to wait two hours to check my blood sugar levels, it's just too dangerous.
Have others experienced this issue and have you any suggestions as to what to do about it?
I do like the alarm capabilty offered by the Libre 2 but I'd rather not have this at the expense of the "uptime reliability" of the system!
Finally, I do know I'm very lucky to get the Libre system on prescription and am very grateful to the NHS team who have suported me here. It just seems so stupid that the manufacturer appears to have taken a backwards step when developing their second generation product.
 
Hi @wd1

I have also moved from Libre to Libre 2 recently, I use android (Samsung galaxy S8) to scan, and I have more scan errors using Libre 2.
Occasionally I get the 10 minute error, but often I get the failed to scan tone telling me to try again, and on the 4th or 5th error tone, the reading appears.
I find L2 is more accurate and I find the errors frustrating, but nonetheless I'm very grateful that I am provided this device.

I agree that the errors are usually when there is a rapid change in blood glucose readings.

I don't use the alarms on L2, as I use xDrip+ that hijacks the bluetooth signal, so it contually displays my blood glucose on my phone and watch, (I can set alarms on xDrip+). So when I can't scan the L2, I've still got a reading that is reasonably reliable from XDrip+, occasionally the accuracy wanders off, but you are able to calibrate it, which I do often.


Even though finger prick tests are annoying, I tend to not mind doing them, as I was doing 15+ a day, and for my work it gives me that extra reassurance that everything is going in the right direction.
 
This may mean that your Sensor tip may not be under your skin. Try to start your Sensor again. If Reader displays “Check Sensor” again, your Sensor was not applied properly. Apply and start a new Sensor.

I had the reading issue sometimes and found that the tip was not in my skin. That's the Q&A on Abbott web site, hope it could help.

If I am playing sport, I find the delay between ISR and BG is too great as my levels may fall too fast.
Bear in mind the main reason for the "try again in 10 minutes" message is that the predictive algorithm which makes up for the 10 to 15 minute delay is unable to compute because the trend is changing too fast or erratically.
Therefore, I will use finger pricks and not rely on any CGM during this time.

Hi,

I found this trouble shooting Abbott page that may possibly help? https://www.freestylelibre.com.au/trouble-shooting

Now I’m not sporty. But I am active. Depends on what kind of sport you where doing.
But I found hand cutting timber (sawing.) with a “Libre arm” in winter with a tight base layer long sleeve & maybe a jacket.
Can cause some scatty readings regarding the “CGM” set up I have with the L2. (3rd party app.)
Scanning with Librelink? Error of some sort.
There is a possibility with the activity & compression from clothing could be confusing how either the sensor is reading and interpreting interstitial fluid. Or the algorithm of the Libre trying to chop sense into it?

Purely conjecture on my part. Hope the link helps?
