Abstract

Claims (13)

1. A method for calibrating a continuous glucose monitoring system, comprising:

positioning at least a portion of a glucose sensor in a body of a user;

obtaining a plurality of signals from the glucose sensor;

determining, using a processor, an acceleration of glucose level increase or decrease based on the obtained signal; and

determining, using the processor, whether calibration is appropriate based on the determined acceleration, wherein determining whether calibration is appropriate comprises comparing the determined acceleration to a predetermined value, and wherein, when the determined acceleration is above the predetermined value, determining that calibration is not appropriate.

2. The method of claim 1 , further comprising waiting a predetermined time period before performing calibration when it is determined that calibration is not appropriate.

3. The method of claim 1 , further comprising performing calibration using a blood sample to calibrate the signals from the glucose sensor.

4. A method for calibrating a continuous glucose monitoring system, comprising:

positioning at least a portion of a glucose sensor in a body of a user;

obtaining a plurality of signals from the glucose sensor;

determining, using a processor, an acceleration of glucose level increase or decrease based on the obtained signal; and

determining, using the processor, whether calibration is appropriate based on the determined acceleration, wherein determining whether calibration is appropriate comprises comparing the determined acceleration to a predetermined value, and, wherein, when the determined acceleration is below the predetermined value, determining that calibration is appropriate.

5. The method of claim 4 , further comprising performing calibration using a blood sample to calibrate the signals from the glucose sensor.
