Abstract
The invention relates to a method for calibrating an analyte-measurement device that is used to evaluate a concentration of analyte in bodily fluid at or from a measurement site in a body. The method involves measuring a concentration, or calibration concentration, of an analyte in blood from an “off-finger” calibration site, and calibrating the analyte-measurement device based on that calibration concentration. The invention also relates to a device, system, or kit for measuring a concentration of an analyte in a body, which employs a calibration device for adjusting analyte concentration measured in bodily fluid based on an analyte concentration measured in blood from an “off-finger” calibration site.

2. A method, comprising:
- determining by an analyte monitoring system a change in analyte value since a prior calibration;
providing a change in analyte value threshold as a function of time elapsed since the prior calibration; determining by the analyte monitoring system whether the change in analyte value as a function of time exceeds the threshold; and if the change in analyte value as a function of time exceeds the threshold, providing by the analyte monitoring system an indication of that determination. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
