I have to arrange a blood test for November. Our surgery does blood tests before 10 as that is when the lab collects! My question is :- my BG never reduces until mid to late morning will this make any difference to the lab results of my HB1AC????
The timing of the blood test won't make any difference at all. The HbA1c, roughly speaking, measures your average blood sugar over the last 2-3 months. It doesn't matter what time of day they take the blood.
