“…46,47 Whereas some authors interpret data as indicating minimal biologic variation in HbA1c between individuals, 4 others have found evidence for more marked differences resulting from poorly understood genetic factors. 48,49 After the elucidation of the nature of nonenzymatic glycation, 50,51 glycation rates have been shown to be subject to variation between individuals by factors that are independent of glucose concentration, including pH, 32 inorganic phosphate, 52 oxidative stress, 53 deglycation, 43,54 and Schiff base inhibitors. 55 These techniques used here, in combination with frequent blood glucose sampling, could evaluate the importance of these factors.…”
