My kids are driving me crazy
“It all sounds so simple in the manual that came with your CGM. You calibrate your CGM the same way you feed squirrels in the park. Or maybe it’s ducks you are supposed to feed. I don’t know, I don’t spend much time in parks. The manuals tells us that all we need to do is enter a fingerstick reading into the monitor every now and then and press a couple of buttons to keep our sensor on course.
True. But not true. Because the devil is in the details.”
Fat Dex is always reading slightly lower than little Nano. Skinny Dex is always slightly higher than little Nano. But little Nano is being used to calibrate both girls, so what’s up with that? I’m not convinced that the Nano is as accurate as my iBG Star, but I don’t really have any evidence for that. Some of it may be I’m just feeling sorry for myself that I can’t use the iBG Star any more… so I might be focusing too much ire on the poor Nano.
But even if it is inaccurate, so long as it’s consistently inaccurate, the CGMs should track closer to each other. Right?
Now, I’ve noticed on a couple of startup cals, where I need to do two fingersticks, that the two Nano readings were quite a bit more off than they should be from each other. Bad luck or bad meter?
So I’ve resolved to do dual fingersticks on the Nano for a while, at least for every calibration stick, just to be sure the Dexs are getting the best possible guidance in their travels through the jungle of my blood sugar.
