Diabetes mellitus control can be monitored by measuring blood levels of Glucose HbA1C Fructosamine Goals for glycemic control are Preprandial blood glucose between 80 and 130 mg / dL (4.4 and 7.2 mmol / L) Peak postprandial (1 to 2 hours after beginning of the meal) blood glucose < 180 mg / dL (< 10 mmol / L) With continuous glucose monitoring (CGM), 14-day time in range (TIR) > 70% (target blood glucose range 70 to 180 mg / mL [3.9 to 9.9 mmol / L]) HbA1C levels < 7% Glucose levels are typically determined by home monitoring of capillary blood glucose (eg, from a fingerstick) or continuous glucose monitoring, as well as maintenance of HbA1C levels < 7%.
