I’ve been told the libre has inconsistent readings. Has anyone else seen this issue?
Yes I have returned my last captor to Abbott for a replacement. After 3 days the readings were between 25 and 40 percent higher than my Next USB. I have used Libre for almost a year but this is only the second one I have returned. I accept 10 to 15 percent différence as a price to pay for ease of use but always keep my NEXT ready to check. I live in France where Libre is now available free under the healthcare system.
In the same way blood glucose finger prick tests can vary, at least with the libre you don't have to wash your hands, or drop a pot of strips on the floor or not put enough blood on the strip........or.......
Yes you can get dodgy sensors (as with strips) and sometimes it can come unstuck/dislodge - Abbott are very good at replacing faulty sensors.
I generally notice a discrepancy of c10% either way and only find this to be a slight issue when bloods are on the low side tending toward hypo.
I've only had one dodgy sensor when the adhesive failed and Abbot replaced sensor immediately.
I've been using the sensors for 7 months now and use the freestyle libre as my main meter.
Yes - big time!
I’ve had several sensors, and with all but one it has generally been about 50% out (it shrieks most of the time that I have low BS, displaying ‘LO’ whilst fingerprick using the same machine and their test strips says 5.6 or so.
Almost unknown for less than a 40% difference, but I do seem to be a minority.
Seems to be a personal physiology thing going on - I’ve actually about to start taking magnesium, as low magnesium prevents the glucose going from your blood into your cells. And I’m going to wear a Libre while I do it to see if I’ve figured out my issue!
I'm timing it so that I apply my sensor before I shall be doing a day of physical work outdoors on monday. so much better than having to prick fingers etc when I am not indoors. I could only afford to buy one sensor as got the money as a christmas gift, I have used them before but it takes a while to save up for them. Ultimately, I need to test my basals without getting sore fingers!
Constantly at least 15% higher than actual blood glucose measured using 2 different meters that are with each other.
I do wonder about the accuracy of these sensors compared with a meter
I have only been on the Freestyle for 7 weeks and absolutely love it. I feel it gives lower readings than on my glucometer but each glucometer gives a slightly different reading anyway. I have 2 different ones and have now decided to trust the Freesyle and go from there.
Bought 3 Libres at the end of August (can’t afford to use all the time) 1 to use immediately, one in case I got a chest infection and needed steroids, and one for general educational purposes.
Just gone to put on the second one, only to discover it expired in October.
Gutted! Not least, because it means I can never have an emergency one in stock again for my asthma management, not with a 2 month expiry.
Oh well, there a hundred quid I won’t see again!
Did you put on the expired sensor to see if it worked? You never know!
2 months seems an awful short time, I wonder if they sent you older stock. (I hasten to add that I don't use the Libre.)
An out of date sensor will still work, it's accuracy might be a bit suspect - but then again it might be perfectly spot on.
Abbott did go through a spell of having short expiry dates - mainly due to stock level issues, but that appears to be fixed now and expiry dates are pretty much 6 months at least now.
