Mine started working this morning, around 4 am, about 12 hours after I put it on. Clearly I should put the next one on the day before the current expires! So far results are it is spot on when the arrow say my BG is not changing, it is within 1 mmol/L when it is the slightly up or down arrow, and up to 3 out on the fast changing arrows. But today was exceptional as I had a croissant which will lead to very rapid changes. (Interestingly when my BG was raising fast it over read, which suggest the lag compensation is over egged in these circumstances as this is not what you would expect, the Libre said I was a 10 whereas my finger pricks never had me above 7) I can also report it works through 5 layers of clothing and with the meter, rather than the sensor, briefly in -15C. Overall very impressed, and now want to figure out how to get the minute by minute readings into something I can play with to analyse.
For me it typically take from 2-4 hours before the Libre results are spot on. It always starts out reporting in the low end. Most often like 2-3 mmol/dl too low, at times up to 4-5 mmol/dl too low. It then become more and more accurate within the following 2-4 hours. As noted by other posters, can only consider its because it has to accommodate to your 'skin temperature' (Have at times plugged a new sensor direct from e.g. a frozen car and that showed lowest and most off the scale of any I tried so far ;o). Likewise it also need to be getting nurtured in its new home for the next 14 days before it will get all the sugars etc floating freely around the sensor needle tip. It is a foreign subject we plunge into the arm, so potentially a minor rupture in supporting tissue has to be overcome before metabolism and fluid perfusion near and around the sensor is back to normal.
Been using it for more than 1 year now. Have not used a 'normal' finger prick + bg meter for last 9 months now, so fully reliant on- and trusting my life on this new gadget. ;o)
Diving, surfing, paragliding, skiing, weekly airplane flights, 4 continents, 25+ countries. High, low, warm, cold, dry or wet. It's been through the paces with me and shown to be working consistently well and deserve my trust. Had only two sensor going bad, and every time my own fault.
I gave the Libre a rest for about a year and had some spare cash so I bought 2 sensors to see if they had improved them and sadly "for my body" they have not :¬(
1st) I think they have changed the adhesive because the 1st new sensor I tried actually fell off before I managed to activate it - adhesive seemed very poor on it
2nd) after 24 hours bedding in I activated it and it read 2.3mmol finger prick read 5.5mmol - Sad Face but it got worse - the next morning I had a bad morning high 9.6mmol on waking and finger prick said 7.6mmol
This trend of 2mmol low when I'm low and 2mmol higher when I'm high is a fully blown trend of this sensor and I am realy disappointed in Abbott's device - I expected some improvements over the last year but no!
In my opinion they should not allow any numbers on their graphs as its all meaningless they should show only an axis less trend line - Or FIX the tech :¬(
I believe from reading some android apps allow the user to "Post" calibrate the Abbott's sensor readings using real blood prick readings and this should be the norm for Abbotts hardware reader
Anyways armed with that info I will buy a new galaxy note 7 and get said software reader and then this might be of some use
<semi-rant off> but I'm really disappointed
(my thread so I hope you don't mind the necro)
Abbot will be great about replacing they always have, but its weekend and they work mon/fri :¬) I willl phone 1st thing Monday :¬)I'm assuming you have contacted Abbott about these latest two sensors? What did they say?
Well I'm on my second sensor first one failed after two days saying it had ended. Most of the readings were within 0.2 mmol. So the second one I've put in 5 hours ago this one was 0.1 mmol deviation so happy days! I put my son to bed tidy around a bit sit down and check 4.3 Jeepers best sort that out! I have a low carb snack and check a few minutes later, I wait and check again same 4.3 going down so I check normally with my freestyle optimum 11.6 Whaaat?! Not a happy bunny two sensors in nearly as many days do I throw more money on duff sensors or give it up as a bad do?
I've had the same nightmares with the sensors and i've now ripped two off on doorframe!!!!! I'm really at the point of unsure whether to continue with them. I have another sensor on its way to me now, which was replaced by Abbott, and i'm really tempted to try putting it on my side or stomach to see if its safer from being ripped off. Not the miracle machine i first thought and forked out a lot of money for:-(Well I'm on my second sensor first one failed after two days saying it had ended.
