The Libre 3+ gets its info from interstitial fluid, not your blood. It is generally a little behind the finger stick reading. Just throw this into your dosing amounts. I usually go by what the Libre says but if very high or low I double check with a finger stick.

I have always had high readings since being diagnosed over 30 years ago. It just does not make sense that it is now running low constantly. That was why I initially posted it to see if this is normal. It almost seems like the readings will go down when I am sitting or in particular over night while I am sleeping. The alarm is very loud and seems almost useless since the readings are always 30-40 points higher. I figured out how to stop the alarms with the exception of when it goes under 60. My point being is that a 59 reading is really a 89-99 reading on a monitor. I was just trying to see if this is a normal thing and if there was any options to make it better. I am do to go for blood work this Friday and then get the results next Friday. I want to see if the results are in line with the CGM. According to it my A1C should be 6.1
