Abstract

A method for storing data at a continuous glucose monitor is presented. The method includes measuring the blood glucose level of the patient. The method also includes receiving a plurality of physical attributes related to the glucose level of the patient. The method further includes determining calibration data based on the measured blood glucose level and at least one of the plurality of physical attribute samples, the calibration data configured to allow the handheld diabetes managing device to determine the estimated glucose level of the patient based on the plurality of physical attribute samples. Finally, the method includes transmitting the calibration data from the handheld diabetes managing device to the continuous glucose monitor for storage at the continuous glucose monitor. The calibration data and plurality of physical attribute samples can be retrieved by a separate device to determine an estimated glucose level of the patient.
