Message: <blockquote data-quote="Gork" data-source="post: 2104340" data-attributes="member: 470595">I am now on my 36th sensor.  Aside from a few failures which were replaced, I have found the sensor readings to be off, on an average, by more then 30%.  Only on rare occasions will the sensor be consistent with the test strip.Yes, I know all about the time delay and the trend indicators but if I were to rely on the sensor to tell me how much to inject then my A1c would be consistently higher.  My trend indicators are overwhelmingly shown as "-" or not changing.   So, NEVER trust the sensor reading. Use it only as a reference.  More often than not, when my blood sugar is on target, the meter is reading LO.  I am back now up to 6 test strip readings a day. Two years ago, I developed a program that logs my statistics.  Within six months (two A1c readings) I went from 9.3 to 6.1.  I now am tracking the % error given between sensor readings and test strip readings and writing a program for a correction factor.  I figure a few more months of programming and Ishould be able to get the sensor to behave the way the company implies that it should.So, yes, expect variance from 10% to 90%, mostly 40%.  This is in my documentation. If you call Libre, they will consistently down play the amount error you should be experiencing.</blockquote>
