Scientific question - what constitutes a prolonged period of exposure to high BG levels? You could say that a Hba1c of 6.1% represents a consistently low, almost normal BG level with some prolonged periods of exposure to high BG levels which you would expect in a diabetic.
So what kind of exposure to high BG levels would cause glycated haemoglobin? 2 hours? 6 hours?
I am coming from this at a completely ignorant angle so genuinely have no idea. Let's say my Hba1c was running nicely at 6.0% and three days before the blood test I had high bloods, struggling to keep them under 8. I've got 8 weeks worth of "good" red blood cells in there but what impact would 3 days "bad" cells have? 6.2%? 6.6%? Or virtually none at all?
Interesting.
