She's reading still high but I am now interested in this "error of margin" thing that could be happening but wonder if its common for higher numbers?
for example I got 292, then tested right after and got 359, and 348? Am I going to have to test 3 times now and go with the one I got the best number with or is the difference in 292 to 350 something not the same as say if she tested 75 and then 120? I thought I read somewhere that the readings in the higher numbers have more error than the ones in the lower numbers and having one read 50 or so points off isn't as concerning as one that is that far off when the numbers are below 100.. hope that made sense, its hard to put into words (also my brain is tired today)
Don’t retest unless you get a wacky number that doesn’t fit in. Don’t worry about meter variance. And yes, the meter variance will be much larger when numbers are high.
Example:
400 x 0.8 = 320 so a difference of 80 vs 100 x 0.8 = 80 so a difference of 20.
If you have a 50 mg/dL difference, than the BG is high enough that you will not have to worry about whether you should be giving an increase or not. In other words, if she’s at 220 and you retest and get 176, and that’s her only blue number, she needs an increase. Again, don’t retest to find out what the meter variance number is.
No, they don’t. And I don’t know where you are talking about on Dr. Lisa’s chart. You’ll have to be more specific. I don’t really understand the question.
