HbA1c Converter

This is just to remind you that the HbA1c measurements have changed. Well, they were supposed to change everywhere but predictably this doesn't appear to be the case. Some people and some articles are still using the old measurements so it is important that we are aware of both.

Here is a table showing the current DCCT measurements, the proposed new IFCC measurements, and the average blood glucose measurements you can expect to be associated with each particular level of HbA1c
