new hba1c conversions

[ebony321]

Hey,

Can someone tell me how to convert the hba1c percentages into the new figures?

also when are they starting to use these in clinics and GP's?

i tried looking at google but it keeps throwing Mmol to Mg... argghhh.

Thanks

Here is one that Ken made a while ago. To get the in between numbers just add 1.2 to the right hand column numbers for each point in mmol/l. example: 4.2 mmol/l add 2.4 = 22.4 mmol/mol. Simples !

Most Lab's now put both figures (HbA1c and IFCC HbA1c) on the printout of your results so you should know both numbers now.

That's the quick reference chart......If you have a Calculator handy......then there is this conversion formula as well from the Diabetes Medication and Drugs Section which is a 'sticky.'

Now I am a stickler for accuracy and seeing some people asking what the new numbers for HbA1c meant I sorted out an easy conversion formula to work both ways.

So, if you want to quickly convert your present HbA1c numbers to the new IFCC HbA1c numbers here is the formula:
Present (HbA1c) - 2.15 x 10.929 = IFCC HbA1c
Example: 7.5% - 2.15 x 10.929 = 58.47 rounded down to 58.

To convert the opposite way.
IFCC HbA1c ÷ 10.929 + 2.15 = Present HbA1c %
Example: 48 ÷ 10.929 + 2.15 = 6.54 rounded down to 6.5%

Ebony,

I've got a calculator here. Only old to new values which is what you asked for. Not for the reverse calculation. Hope it works:
