RE: [IP] correlation between HbA1C and average BG



Having a difference between your ave and the predicted average is quite
likely.  As the HBA1C should suggest a real average and your testing average
is from discrete points.  If you happen to test on mostly high points in the
real curve then you will get a higher ave than reality from you sporadic
tests.

The more you test the closer you will be to the real ave.  If you only test
once you could be way off but you would still have a test ave.

The constants in the formulas are different for different lab 
standards.
