HbA1c: Where are you now?

Published online: 
02 September 2011


On 3 October 2011, laboratories in New Zealand and internationally changed the way HbA1c results are reported.

The change makes it much easier to compare HbA1c results from different laboratories and research trials around the world.

What is the new HbA1c?

The measurement is in millimoles per mole (mmol/mol) instead of a percentage (%).

Please note that while the results of the units are different, the test stays the same.
