BACKGROUND Most continuous glucose monitoring (CGM) devices measure a current, proportional to the interstitial glucose (IG) concentration, which is converted into a glucose level by a standard device calibration step that exploits some blood glucose (BG) references. However, data show that deterioration of sensor gain may occur, which can affect CGM output by a systematic and possibly large (e.g., up to 15/20 mg/dL) error. Enhanced calibration algorithms for improving the accuracy of CGM are… CONTINUE READING
