I too use up time, energy and strips seeking an accuracy that is just not on offer. This morning fasting I got 5.6. Not happy, so I instantly re-tested from the same drop of blood and got a nice 4.8. I considered using a 3rd strip, but then wondered what the point would be. Would I believe the 1st, 2nd, 3rd or an average of all 3?
The one time I tried a Libre sensor I also liked the arrows, but the Libre seemed to read much lower than my strips, which in turn read lower than my A1c
I think none of these readings are to be taken too much to heart. They do motivate me to try hard. As long as I'm not injecting insulin or taking insulin-producing meds, false lows should not alarm me too much. I'm not at all convinced that I can keep from being upset by false highs, though.
