[QUOTE="Fleegle, post: 1505486, member: 402985"] Hi - I have had the Libre since May. My experience has been as others have said - in the first couple of days readings lower than truth and in general a little lower. In saying that who knows what is telling the absolute truth given blood meters compared back to back do not say the same thing. I find mine is never more than .5mmol out well within the 15% meters need to be accurate to. And I find the increase and decrease to be very accurate and very helpful with food spikes particularly with telling you peek time and value. Make sure you record food on the meter just before you eat it and then when you download into the software you get a marker which tells you at what time and what value your peek was. You miss that with the one and two hour meter test. The lag is between 5&10 mins. The fluids in the skin respond later. It is interesting when you download the figures because the graph seems to correct time somewhat and the asterix's of BG test are nearly on the curve (providing you use the inbuilt BG meter). I try to not scan so often now because the one time scan can be a little misleading where the 15min graph line seems more like an average in that 15min so you get a far better feel of the trends. Ok you might miss an absolute peek in that 15mins - but if it is high leading up to and following it all comes out in the average anyway. Really interesting also to see stress, tiredness and physical activity. I try and put my sensor on two days before I activate it for best results. However, warning - one early morning I scanned the wrong one and then accepted the start new sensor :) Now that was the worse of both worlds - ended a sensor two days early and had no warm up on the other one :) [/QUOTE]
