+/- 15% as it happens, and that's from a sample tested against a very specific test. Then of course you have the values when glucose levels are below 4 mmol/l where that variance is subject to a slightly different comparison.place of manufacture must conform to a tolerance of accuracy of no more than +/- 10%

On that note, does anyone know if Libre works with iPhones yet?
Over 17 years t1.. mylowest hba1c has been 72. Libre started on it it January this year... the libre estimated 56 then 54 then 62..my results were 53 50 and 60. The best it's ever been. I'm on my 16th sensor.. 1 failed after 6 days. 1 never started 1 I knocked off.. I just keep showing hypo... 1 call to Abbott's.. replaced without question within 3 days. I finger prick every now and again.. always within 1 or 2 of the blood meter.. on the odd time it's more than 2 out.. it's always with an arrow pointing straight up or down.. which indicates it's rapid change.. . So you can see...whats happening.. . For me thankfully.. it sticks like...well you know what ! It's the best... a real game changer... brilliant device.Not using control test solution? Quite frankly I find the concept of taking insulin or glucose on the basis of what an uncalibrated meter tells me to be ill advised at best and just plain bonkers at worst.
I would ask you the same question I pose to all Libre users. Please do not however feel compelled in any way to reply. What is the difference between your most recent HbA1c result from your doctor or DSN and your predicted A1c reading from your Libre? If it is within 5 points hats off to you too. I think you will find you will be in a distinct minority.

And notice @Diabeticliberty, for low bgs below 5.6mmol/L it simply states that it should be within the fixed range of ± 0.83 mmol/L of laboratory results. So for very low bgs the uncertainty can become a very high percentage, even near the absolute value you read on the meter. As I described above, you cant really trust any mobile meter when measuring low bg levels, down to the level of digits you showed on your screenshot.I have managed to confuse myself. Having gone away and checked this I am coming up with +/-20% for concentrations of 5.6mmols or more. I have always been under the impression it was only 10% for concentrations of 4.2mmols. I will take advice on this one
I wish I did have £100 a month to spare. I do not eat out, drink beer etc. Like most people I just get by every month.Cost - probably the elephant in the room for most, but really, I think most people can find £100 a month, whether it means less meals out, less beer, less etc, I'm sure most of us can find £25/week if we really want to.
I see what Libre does not show about the sensor which is that it includes a relatively long sharp (needle) in your arm that stays in your arm until replaced in 2 weeks
Hi,
While I grumble at paying £100/month for sensors, credit where it's due.
It's a game changer for me, the challenge for me is finger pricking, I just can't do it during my work hours, because I'm in a lot of meetings, I know this is a poor excuse, but you just look like a pleb if you're busy drawing blood and etc during meetings with senior stakeholders and etc.
Also I can't be bothered to prick as often as I really should.
Accuracy - it's super accurate for me, matches my One Touch Verio which has been my go to meter for a few years now.
Easy of use - if you have a NFC smartphone no need for their silly reader, no need to carry an additional device. The software is pretty sweet.
Application - I've had no issues with mine, I've stupidly stuck it in my tricep, and done a work out that involved chest and triceps and no weird pains or etc. There is a slight sensation as it's living inside my tricep, but nothing too concerning.
Cost - probably the elephant in the room for most, but really, I think most people can find £100 a month, whether it means less meals out, less beer, less etc, I'm sure most of us can find £25/week if we really want to.
Blood sugars - I was soaring all over the place, and truth is I stopped testing my sugars consistently years ago...but not anymore, within 3 days I'm getting closer to the 5-7mmol range. I've only finger pricked around 5 times since to validate my trust in the Libre sensor. I've got good hypo awareness so generally have a feel for where I am...
If anything, and if there are any Abbott reps on here, perhaps you could look into a discount code or something for those of us who fund it personally. I know there's a code floating around for free delivery, but even a 10% code or similar would really help...

For calibration above, you have the calibration chip from Roche you have to use when starting a new batch of strips. Or it wont even allow you to read. That is the only 'calibration' if you will possible of your meter. If you start to consider using calibration liquids on top because you feel the need to double check that it works, then you are out on thin ice already if you don't trust yourself or the equipment you use. E.g. you would then need to measure with calibration liquid before every single test you do. And can you trust the calibration liquid is still good? The questions quickly start to pile up.
I think you expect scientific precision, but there is none not even close. You get a good indication about your bg from your meter. That is it.
I am sorry DL, I forgot I moved through many Roche meters through the years, think the last ones were Roche AccuCheck 'Compact' and then the last being the 'Mobile'. So yes, you have a control test solution. But it has nothing to do with calibrating the device. As you cant calibrate them.The AccuChek Mobile device does not use strips. It uses a cassette. Nor does it utilise a calibration chip. It uses control test solution. If you are happy to implicitly trust your Libre then I hope it brings you much happiness. For my own part I remain sceptical regarding its accuracy or lack of. My own Libre suggests that I have low blood sugars when I clearly do not. This is backed up by my AccuChek Mobile. My AccuChek Mobile is backed up by another AccuChek Mobile. Both are backed up by control test solution. I feel it appropriate to leave it at that.
