Cool. How did you work this out? I was told at my last review in Nov that the HbA1c was changing but have forgotten how the new way is calculated?
Thanks, Anele Smile



If you CLICK HERE it will take you to the Diabetes UK HbA1c calculator............. Wink
Thanks very much Novorapidboi26. Very Happy
Will check it out .
Many thanks,
Anele.
There is also a graph that a member of diabetessupport.co.uk made up HERE

Knew that I could rely on you all to review.

We need accept the new units as in the future this is the way that all Path Labs - worldwide, will report.

Thank You whiskysmum and novarapidboi26 for your valued input.

Have a table.....when I can put my hand on it....that we can use as a reference

How do old and new relate?
The relationship between the new IFCC reference method and the current “DCCT aligned” assays has been stable over several years. When HbA1c results are expressed as % haemoglobin, the equation describing the relationship is:

IFCC-HbA1c (mmol/mol) = [DCCT-HbA1c (%) - 2.15] x 10.929 Cool

A guide to the new values expressed as mmol/mol is:

Current DCCT aligned HbA1c(%) New IFCC HbA1c (mmol/mol)
4.0 - 20
5.0 - 31
6.0 - 42
6.5 - 48
7.0 - 53
7.5 - 58
8.0 - 64
9.0 - 75
10.0 - 86
What are the targets in new units?
The equivalent of the current DCCT HbA1c targets of 6.5% and 7.5% are 48mmol/mol and 58mmol/mol in the new units, with the non-diabetic reference range of 4.0% to 6.0% being 20 mmol/mol to 42 mmol/mol.

Hope that registers with us all..........
It is just a straight forward conversion using some constants...........If you are anything like me.....Keep It Simple Stupid......the KISS principal for all Engineers...use the table!
I'm sure the gentleman in the know would be able to incorporate this formula for HbA1c conversion within the apps to enable showing either value in record keeping.

Best Wishes to us all for Christmas Very Happy
