[QUOTE="Mungobean, post: 2472960, member: 545261"] I have found the readings can be way out at times (up to 6 Mmoll different). I was getting obsessed with the differences and my DN said to stop stressing about it and to just use the Libre readings; and then if you get a high or low reading, then double check with a blood prick. I find the Libre invaluable, especially for the trends, so long as you are aware that you need to check your lows especially. For me it is far better than getting sore fingers, as my BS fluctuates wildly, and so I was pricking many times per day. I have found that some sensors are better than others. If you keep a record of your readings and your finger pricks and they are consistently very different, you could have a duff sensor; I have had some duffers and if you contact Abbott and give them your readings, they are very good at replacing the sensors. I have also found that it helps to attach the sensor for 24 hours before activating it, and for me the readings tend to be more inaccurate at the very beginning and the very end of the sensor’s life. I have found peace with my sensor use, in recognising that the readings rarely match a finger prick, but they do seem good at recognising trends - so you can see if you are going high or low, which I guess is the most important thing.
