  • 1.  LIBRE 2

    I am having trouble with these. The last three I have used it has been necessary to ring Abbott and report faults. Not the first time in the years I have used them as having to report faults at least every two months. The last three in a row has got me upset. While Abbott replace the faulty sensors, it is not a simple process. Many minutes on phone and often it is difficult to understand the person dealing with my issue (usually average english).

    Has anyone got some advice as whether Libre 2 or Dexcom system is better and how reliable is the Dexcom system.

    David, I also had problems with three L2's recently, so I think they had a bad batch.  But my last two sensors since then have been accurate and reliable.

    The first bad sensor had a bias, but that was manageable and I didn't seek replacement.  I had two sensors replaced because one was far too inaccurate and the other expired after a couple of days.  

    For each, I crossed-checked results with finger-prick tests via a very old Freedom Lite (15+ years ?) and a modern Libre 2 reader.  The two finger-prick devices agreed very well, which I thought was impressive.  I use a timer on my phone to delay the L2 scan to accommodate the delay between finger-prick and interstitial readings.

    The two sensors were quickly replaced at my request but, yes, I had to provide my test data and serial numbers of the finger-prick devices etc.  They only wanted three test readings, which I think is insufficient, but that's their problem.   I also needed to upload the error data to Abbott.    Because my Freedom Lite was a far beyond support, they also replaced that , which I didn't request.  I had to return the bad sensors and apparently they're checked in Sydney, but I can't imagine Abbott spending time to check all the devices that are returned on a global basis.

    Call centre people in most areas these days are based overseas, but I've never had a problem understanding Abbot's people.  My last person seemed to be well informed and was based in Malaysia.

    As a monitor/control device I don't expect them to always agree with finger-prick readings but we should cross-check periodically.  Both finger-prick and interstitial devices are just an estimate of the true BG and I'm very grateful to have them both - much better than the old urine test-tap which I used for many years.  But I'm looking forward to the Libre 3.

    It will be interesting to hear about the experience with other brands, because I've only ever used Libre.

    Hi !

    I have had very good results with the Libre 2. One or two failed but were replace quickly.

    The main issue I have is that Abbot does not let the user know why the device failed. This means that if the problem is caused by the user there is no feedback to allow  me to modify what I am doing.

    Abbot really needs to modify this process !

    Paul, I agree about feedback. 

    Once, I complained about the lack of feedback and was given a code to put on the returned box which calls for feedback, but no feedback arrived.

    Hi David 

    I'm still at the dinosaur stage using multiple injections in combination with checking blood before meals and a CGM.  Check out the article below. 
    The multinationals are fully aware that their devices are not exact, in fact up to a 20 percent discrepancy! My endocrinologist mentions testing 5 fingers may get five different results which is most probably similar to the CGM testing.  
    An article in Beyond type 1 states  "Every FDA-approved BGM and CGM technology in the United States must be within 15 percent of the true laboratory value at least 95 percent of the time. It also needs to be within 20 percent of the true laboratory value at least 99 percent of the time."


    Would it be too much to expect from a huge multinational, the Libre3 already on sale internationally yet for some unknown reason not in Australia, with its improved technology? Abbotts state that it has huge improvements and is even smaller than the libre 2. 

    I always have a spare CGM in the cupboard just in case mine stuffs up, falls off etc etc   I find Abbotts help centre helpful and swaps duds readily as they most probably don't want consumer complaints.  It appears that their lack of information to Diabetes Australia and members on this forum about new models such as the Libre 3  is a reflection of their attitude.

    Hi David

    i have used L2 in past and currently wear Dexcom G6, I prefer the accuracy of the G6, overall it is very helpful to managing bglz. I wear it on the back of upper arm for best results, out of sight (well almost) and out of mind. The readings i can go with, i still have hypo awareness so i am aware of changes to my nervous system e.g. eyesight, balance etc., so i think the g6 is very good. The cross check with bgl monitor is usualy good but if a big difference there is a need to investigate a bit further, do a 2nd prick.

    call in support is 24/7 & cannot fault it, replacing a sensor no problem there also, really keen to get my hands in updated cgms.

    i give a big tick to AMSL, very helpful.

    cheers Timf

    Have not been on the forum for a while but have been following discussions. With regard to the Libre, I am afraid I have a very low tolerance threshold for fails and veery high expectation for support. Given these parameters, I swapped to Dexcom around the time L2 came out and would never go back. The level of support is too amazing  (24/7/365 and all from Australia) to go to any alternative. Just a few basic questions, no need for data etc etc or returns (unless it is the transmitter). For the last 6 months have been using the G6 with and Tandem TSlim pump. I joined the Loan to Buy tSlim program in October while I wait for my private health insurance upgrade qualifying period to come into effect next year.  Great initiative from AMSL. Rarely have a problem with sensors but always resolved almost instantly even in the wee small hours when my initial trial pump from my CDE had a hissy fit on a weekend. I was stressed out but the support was truly amazing and fixed over the phone in almost no time. The G6 with the pump seems to be even more accurate than with a reader (I dont use a phone) as well.

    With so many fails I'd be changing my CGM. Should not have to go through so many hoops just to replace a sensor. I got a replacement for a sensor because I had a scan scheduled the day after it was due to be changed. Apparently AMSL has a policy of replacing when the sensor has to be changed for a medical procedure. I had only asked advice from the tech team about whether devices had to be removed for the procedure and they offered the replacement.

    Can't speak too highly of their support and service. which is something we should be entitled to for all devices, and we should not be so surprised when we get it . 

    Good luck with future sensors.
