[QUOTE="domoboy, post: 2639172, member: 533931"] Thanks everyone, I've been a T1 Diabetic since the age of 7, so when I went onto Libre about 30 months ago I was blown away. The main benefit being able to see the direction of travel simply by scanning after 5/1/15 minutes (I don't trust the arrows). What I will also say is that I get incredibly good warning signs for both low and high blood sugar, and this weekend was the first time I've ever had a low on the libre and not actually felt low! Hence why I finger pricked in that instance. Yes I agree it's a shame thats the guidance I got! I shall calibrate (by this I mean, test my finger prick versus my Libre) a lot more often going forwards now. Especially for high and low readings, and probably at least once or twice a day anyway just for a comparison to ensure it's working semi-correctly. I do however, still think there is an issue. Whenever I have calibrated in the past (which prior to the last few days, was probably only a couple of times a week) it's always been within -05, usually within 0.2 tbf, unless I've been going through a period of transition, in which case 10 minutes later the Libre has been within 0.5 still accounting for the delay. My hbac1 has also been the same as my sensor prediction for each one which makes me think it did used to be more accurate previously? As you can see from the numbers, the difference between the finger prick and the Libre readings are showing fairly significant differences. I understand the MARD should be under or around 10% regardless of first day wear or not? I've also been seeing a ton of complaints on reddit since the Libre 2 updated to a CGM, with a lot of people reporting inaccurate glucose readings and sensors failing. Someone's diabetic midwife on there has apparently also noticed a theme in the last few weeks and is raising it with Abbott due to their hospitals concerns with the sensors. I've returned the two faulty sensors to Abbott for them to look at on their end. Thanks again, [/QUOTE]
