The a1c has been the bell-weather of control since it became available.
The bottom line is this: Most of us know when we're doing something to make the situation better or worse. I don't need a meter to tell me that the hot dog I just ate on that sweet, white bun is going to cause a big jump in my BG for a couple of hours.
Further, my fasting BG is going to be dependent on how I treated myself yesterday.
I am not arguing against the HbA1C test by any means. I am simply stating a truth - that the A1C can be fooled, just like any other test, including plasma glucose tests.
I am also questioning the motivation for the change in test standard, as well as any modification to the range of numbers that are considered to be diabetic. That’s not a refutation of the science.
I will retract my criticism of the HbA1C test just as soon as someone can prove it isn’t possible to foll it (which necessarily includes re-diagnosing the issue I am dealing with now, along with my doctors). Until someone can refute the truth, my criticism stands.
As do my questions regarding motivation.
