[QUOTE="CherryAA, post: 1336536, member: 327005"] I have had three of these so far, The first one gave me readings that pretty much accorded with the Codefree fingerstick tests I had been doing. The second gave me readings far lower than I expected 4's andf 5's instead of 6's and 7's , though they did agree to the Abbott stick test. I did also check those against a couple of codefree and they showed maybe 0.5 -1.0 under-reporting ie my daily averages were probably closer to 6.1-6.5 compared to the reported 5.4 - 6.1 The third one gave me much higher readings than either of the first 2 and started reporting 10's and 11's that I have not seen in a while using the codefree, Abbott's its own internal blood stick tests were coming out much lower - 2-2.5 mols and the daily averages suddenly became 7+ compared to 5.4 a day earlier. Abbott are sending me a replacement for this one It is now clear to me by day 3 of each of the three units that the numbers were going to be very different for each monitor. It is very disappointing as clearly it doesn't really help me control anything much if its figures are just random. Abbott itself said it was ok if the numbers were as much as 30% different between fingerstick and sensor tests - which seems ridiculously high to me. On that basis 7.8 could show as anything from 5.5 to 10.1 , though the guy did also say that if they were obivously more than 2 mmol out it would be replace - ie 5.8-9.8 a slightly narrower range - however as one of those is fine and the other panic I am not too sure what the point of these monitors are now I have tried them. I am aware that other people have been using them for a while now, It would be useful to know if those who are a lot more familiar with them have also seen this phenomenon - i.e. have your monitors been internally consistent from sensor to sensor or do you know within a couple of days if that particular monitor is reading heavy or light and then make mental adjustments?
