My Minimed trainer instructed me to calibrate my sensor between 2-4 times daily and no more than that because it tends to throw off the numbers. A couple of different days I have accidentally calibrated 5 or 6 times (my darn thumb was too quick on the trigger), but in both cases my sensor numbers matched my meter BG’s much more closely. Has anyone else had this experience? Why would that be?
Yes the same thing has happened to me. The only thing you really have to watch is that your bs is not falling or rising quickly when you calibrate. If it is stable it just adjusts it enough to make it correct. This comes from my trainer and experience.
I update mine when I wake, before I eat and before bed and it works much better that way at least for me.
I tend to test before I put the food together on my plate so there is a delay of 5 to 15 min before I take insulin, Minimed told me it is best to calibrate 15 min before taking insulin and this has seemed to help. I am not sure why though I know some who calibrate 2 times a day and there readings are good also.
Be well and be loved
I’ve had my Minimed sensor for about three weeks and it is awesome!! My trainer told me to set the glucose meter up to manually input the readings, but after a few days, I changed it to automatic and still input it. I do not test whenever there are arrows. Sometimes it’s 20 numbers off from the sensor but sometimes it’s about 4 numbers off. It has certainly kept me from bottoming out at night. I hear the alarm and I just pop a glucose tablet or two and I’m good for the rest of the night, far different from before I started wearing the sensor and almost lost it.
Based on personal experience with my MM 522 CGM I do believe it’s possible to tweak the level of sensor glucose accuracy by inputing more BG callibrations so long as you’re certain, by monitoring your sensor glucose trendline, that glucose levels are close to flatline (stable) - and SG is relatively close to BG values.
