I disagree. The hbA1c measures the glucose molecules that stick to
hemoglobin. This is a non-linear process, it is not simply an
average of highs and lows. A few highs that last awhile cause a lot
of damage as opposed to a few short peaks. The lows don't really do
much at all.
A simple formula converts the hbA1c to the sort-of-average your
you will find that this is quite a bit higher than the average you
see on your meter. That is because of the sticky effect of the
glucose molecule. Basically it is a measure of the glucose stuck to
the red blood cells that are alive in your body. Since they are
replaced completely about every 90 days, this gives an overall
indication of the level of control.
Don't mistake my point, I am not advocating big swings in bg. Simply
that the HbA1c is a more sophisticated measure of control than simply
looking at your bg's even if you test a lot.
