I had an embarrassing surprise on a
diabetes forum lately when I questioned an HbA1c value of 49. The
person was from the United Kingdom and I admit that I was not
familiar with the change in values. There may be a few other
countries that have adopted this, but I have not encountered them as
of yet. Australia apparently has converted to the new system.
The InDependent Diabetes Trust (IDDT)
is the organization that developed the new system. This table is
from their newsletter.
| HbA1c (DCCT) Current measurement (%) |
HbA1c (IFCC) Measurement from October 2011 (mmol/mol) |
| 6 | 42 |
| 7 | 53 |
| 8 | 64 |
| 9 | 75 |
| 10 | 86 |
| 11 | 97 |
| 12 | 108 |
| 13 | 119 |
I need to thank Tom Ross for the
information he had in his November 12, 2015 blog. His
information starts at “More risk-assessment!” which is a ways down the
blog. Tom does give us a converter link and
this will help us convert to the new standards of HbA1c readings. I
would urge you to read Tom's blog.
This means that those of us in the
United States will now have another conversion to make to understand
when seeing information from some other countries.
