No I don't think he does.
I only just learned of this myself, will read the article later, as I have to go to get my son from school shortly.
But it does make sense what I have read of it already.
My fasting glucose was slightly out of the normal range, but the avg over 3 months was in the normal range, this he could not explain. But my insulin.
Normal fasting >10, and after eating it can be up to 30, mine was 150 the first test, and because I asked if it was a mistake since it was so high, he repeated it, and it was 127
