I've used all three generations of the Freestyle Libre CGM (blood sugar monitor) over the years. applying the sensors to the back of my arms per the instructions. With all of them, I've noticed that sensors applied to my left arm seem to read 20-40 mg/dL higher than sensors applied to my right arm. Given my CHF, low EF, and low blood pressure, does this sound normal?

When I do lab bloodwork, the sensor on my left arm at the sample time seems to be in line with what the lab reports show (granted they use completely different testing methods).

The reason why I'm asking is because I've been jarred awake for the past few nights from OCD psycho dog pawings to the head because he hears the low glucose alerts. I'm pretty sure that they are false alarms, but don't want to disable them or lower the threshold any further in case it is actually low.....
