A1c conversion to percentage

[weecee]

Evening all. I am currently reading The Johns Hopkins Guide to Diabetes book and it is very interesting. They refer to the A1c readings in percentages. Does anyone know if there is a formula to convert from number to percentage, just to make things easier. Cheers

To make it easier for you guys, I convert all my readings to the UK format..... mg/dL to mmol/L is easy, just divide or multiply by 18..... for HbA1c I use http://www.diabetes.co.uk/hba1c-units-converter.html

I've never been told about the 90 minutes after meals target, I wonder why?

Yes, I've always been told 2 hours afterwards. I think though that it's a slight misquote/omission on the DUK site as the NICE guidelines state 'glucose level of 5-9 mmol/l at least 90 minutes after eating.'

Here it is in full from the NICE guidelines (NG17) for Type 1 in adults 2015:

Blood glucose targets
1.6.13 Advise adults with type 1 diabetes to aim for:

• a fasting plasma glucose level of 5–7 mmol/litre on waking and
  
  
• a plasma glucose level of 4–7 mmol/litre before meals at other times of the day. [new 2015]

1.6.14 Advise adults with type 1 diabetes who choose to test after meals to aim for a plasma glucose level of 5–9 mmol/litre at least 90 minutes after eating. (This timing may be different in pregnancy – for guidance on plasma glucose targets in pregnancy, see the NICE guideline on diabetes in pregnancy.) [new 2015]

1.6.15 Agree bedtime target plasma glucose levels with each adult with type 1 diabetes that take into account timing of the last meal and its related insulin dose, and are consistent with the recommended fasting level on waking (see recommendation 1.6.13). [new 2015]
