I'm not quite sure what you mean?
There is 2 ways of measuring hba1c, the one you have stated and a mmol/mol which yours would be 7.5% in the "older" way, it equates to an average BG of around 9.3mmol via finger prick
This isn't borderline though, this is high, as a Type 2 your targets should be 4-7mmol via finger prick before meals and under 8.5mmol at least 90 minutes after a meal
