If you got the same unit that I got, the numbers are "plasma
calibrated," which means that even though the tested sample is whole
blood, the reading is adjusted to be what it would be if it had been
plasma, i.e., 12% higher. In that case, you don't have to do any
conversions yourself. If it's just an unconverted whole blood reading,
then to be comparable to what you'd get from your doctor's lab results,
you must add the 12%. My old glucometer didn't do the conversion, so
that's why I added points.
It's pretty standard practice to test FBG in the morning, because for
most people that's the only time of day when they've not eaten for any
length of time. But because of the dawn phenomenon, it might be somewhat
higher than it would be if you tested later. I'd say try a morning
reading and then, if you normally eat breakfast, try skipping lunch and
get a mid afternoon fasting test. Then check 2 hours after dinner. In
some ways, the 2 hour postprandial test is the most critical one, for
revealing insulin resistance. In a non-diabetic BG should be at or
close to fasting levels by two hours after a meal.
And my personal goal is to get FBG to 83 or lower, since that is
apparently what the pancreas thinks it should be. I am now occasionally
getting readings that low, but the average is (now) in the upper 80s.
Your average BG over a period of months indicates what your Hba1c would
be, but converted to the international scale, which is mmol/liter
instead of md/dl. You can do this conversion yourself by simply
dividing by 18.
