My current sensor is going properly haywire. I usually do a BG test in the morning just to check it, and so far it had always been within 0.5 of the scan unless things were really changing quickly.
Yesterday morning the sensor was reading 1.5 lower than BG. I know being dehydrated can mess with it, so I drank plenty of water - by lunchtime it was only 1 off, but then by the evening it was reading 2 points lower. This morning it's 4 points lower and thinks I was hypo all night - I don't believe it.
I want to call Abbott but I'm not sure which number to use, or whether they will be working over Christmas?
