Self-monitoring of blood glucose (SMBG) is one of the two primary techniques available for health providers and patients to assess the effectiveness of the management plan on glycemic control in diabetes. SMBG is typically carried out in the form of frequent fingerstick capillary glucose testing. Another more recent technology available is continuous glucose monitoring (CGM) carried out through a sensor that measures interstitial glucose concentration which correlates well with plasma glucose and capillary glucose levels. The second glycemic control technique is measurement of hemoglobin A1C (Hb A1C). 

Because measurement of Hb A1C is primary, the most accurate glycemic control tool available, it is important to correlate Hb A1C results with ones obtained using SMBG for long-term metabolic control and management of diabetes. Recently, the international multicenter A1C-Derived Average Glucose (ADAG) trial successfully completed and results determined that the correlation between Hb A1C results and eAG (the new term used to combine both CGM and fingerstick capillary glucose testing) is strong enough to justify reporting of both an Hb A1c results and eAG result
