I think were the confusion is arising , is that Hba1c is expressed as a figure in mmol/mol.
If you wish you can equate it to an average glucose reading that would be in mmol/L this is a higher figure, and would be the equivalent of what a blood meter would read, if you did a test.
They are not the same reading, a Hba1c should be expressed in mmol/mol,
Hope I make sense
That is exactly what I was saying, so I don't understand why you are saying an HbA1c of 42mmol/mol is 6mmol/l. It isn't. It is 7mmol/l.
If anyone wishes to compare their HbA1c to what their meters are saying, they need to convert it to mmol/l, which will always be a higher reading than the old HbA1c percentage figure.
HbA1c 5.7% DCCT is 39mmol/mol in new money, which converts to 6.5mmol/L as per our meters.
HbA1c 5.9% is 41mmol/mol which converts to 6.8mmol/l as per our meters.
Nearly there ....then ... I don't convert my hba1c to a third number ...just for example 5.9% to 41 mol for hba1c reading I except those ...
Or rather I understand those results ....
