A1C of 70 I have not heard of, unless it is the new system use in UK, which would be in mmol/mol (IFCC)
Unless you meant 7.0 % ?
I found the UK new value system, scroll down to see the many charts in there.

Found another site to calculate conversion https://www.hba1cnet.com/hba1c-calculator/

By entering your 70 the results are below

HbA1c in mmol/mol (IFCC) 70
in % (DCCT/NGSP) 8.6
Average blood glucose in mg/dL 199.11
in mmol/L 11.05

Hope this helps.

70 A1C converts to 8.6 A1C and to an average daily reading of about 11 mmol or about 200 USA. Definitely not in control.

Do what you want with this information.

Yes it does absolutely thanks s lot & highly appreciated
