My last hbAIc was 71. I tried to work out what that meant by looking at the Diabetes uk website and was emailed the result 11.2 mmol/L. That doesn't seem to tally with 78 equalling 9.3. I'd be grateful if someone could explain. Maths is not a strong point!
HbA1c used to be measured in DCCT units and given perents, e.g. 9.3%. Recently, this was changed and all BG are now to be reported in IFCC units, e.g. 71 mmol/mol. These are equivalent units
The tool on diabetes.co.uk "helpfully" lists another figure which is the average blood glucose level you'd expect to find in someone with with your HbA1c (e.g. If your HbA1c was 71 mmol/mol then you'd expect your average BG to be around 11.2 mmol/l). These units are not equivalent - it's a regression estimate.
I don't think that you'd ever need to know this last figure unless you wanted to predict your HbA1c based on your meter average or something along those lines.
