Surprisingly, I have not found this to be the case.  Claire's first meter, a 
Glucometer Elite read 4.1, lab said 4.2 at her very first specialist diabetes 
appointment (they were not pleased, as this was too low for a just turned 3 
year old).  But they were quite amazed at the meter's accuracy, I still have 
this 60 second meter.  At subsequent tests, results would be something like 
16.2 meter versus 16.3 lab.  Again only a one mmol difference, despite the 
grossly different glucose readings. 

Our current meter in use, an Ultra one touch, is exactly the same.  When 
tested is one mmol different from the lab, both at low blood sugars (4 range) 
and high blood sugars (16 range).  Kinda curious, as I also thought it would 
be a fixed percentage difference.
