I just got my new OneTouch Ultra yesterday. My old one is an
Accu-Check Advantage.
The OneTouch is consistently 20%-25% lower than the Accu-Check.
All readings were made at the same time. Both were properly
calibrated.
Confucius say "Man with one watch know what time it is, but
man with two watches never quite sure!" I can now identify
with this proverb.

How old was your Accu-chek? Mine matched lab readings for several
years--up through this past June. But recently I started to wonder about
it, and then, this past week, it suddenly started acting like a random
number generator.
I bought a cheap Walgreens meter, for comparison and the Accuchek was
all over the place--the new meter would read 125 and the accucheck would
read 170 one time, then they'd match at another time, then the Accuchek
would be 25% lower.
The people at the Accuchek regular customer service number sent me new
control solution last month, and it tested out okay. But I called a
different, replacement number at Roche that my health insurer gave me,
and the woman there told me that the Advantages tend to stop working
properly at about 2.5 year old. That just happens to be the age of this
one. (She didn't know that.)
They sent me an Aviva and it matches the Walgreen's meter very
closely--within a few mg/dl.
So it is possible your Advantage meter was getting old. TOO BAD that
Accuchek's general customer service number doesn't give out the same
information that their replacement line does!

Mine is about that old, maybe a little older. Does anyone know a way
to get a one-time check someplace, just for comparison with my new
OneTouch that I will take with me?

Could it be time to change the battery, even if the "low battery" warning
hasn't yet appeared?
