we have developed an error grid analysis ( ega ) , which describes the clinical accuracy of smbg systems over the entire range of blood glucose values , taking into account 1 ) the absolute value of the system-generated glucose value , 2 ) the absolute value of the reference blood glucose value , 3 ) the relative difference between these two values , and 4 ) the clinical significance of this difference .
