A1C Calculator

Right, but don't most Dr.'s offices use the Glucose and not the Plasma one. I've never heard anyone say a 6.9% A1C is in the 160s - always in the 140s.

Probably.
Since Accu-Check used the plasma calc on the website, makes me question
what other meters are showing. The problem there is the meter is really such a small snapshot of the
big picture. So can't really put much weight in the value it gives you.

Either way, it's the same A1c using two different methods.

This is nice information to have just to check on things periodically.

Thanks for sharing.

From what I know... lab equipment uses plasma readings.

Home meters can only measure whole-blood levels, but they show the levels in equivalent plasma - they are just calibrated higher since we know the usual difference between plasma and whole blood.

So, we should use the plasma levels in order to draw correlation to the meter readings we see.
