1. A method of reducing false readings in a hypoglycemic detector, said method comprising the steps of:
- establishing a predetermined hypoglycemic threshold;
establishing a predetermined critical threshold, said predetermined critical threshold being below said predetermined hypoglycemic threshold;
establishing a predetermined rate of change in glucose concentration; and
calculating a first sampling rate based upon said predetermined hypoglycemic threshold, said predetermined critical threshold, and said predetermined rate of change in glucose concentration.

Abstract
The present invention is directed to a method of reducing false readings in a hypoglycemic detector that includes establishing a predetermined hypoglycemic threshold, a predetermined critical threshold, a predetermined rate of change in glucose concentration where the predetermined critical threshold is below the predetermined hypoglycemic threshold. A first sampling rate is then calculated based upon said predetermined hypoglycemic threshold, said predetermined critical threshold, and said predetermined rate of change in glucose concentration.

11. A method for establishing a critical sampling rate for a continuous glucose monitor comprising the steps of:
-
establishing a preferred number of measurements within a target zone, a predetermined critical threshold, and a predetermined hypoglycemic threshold; measuring a plurality of glucose concentrations at a predetermined first sampling rate; calculating an actual rate of change in glucose concentration based on said plurality of glucose concentrations; modifying said first sampling rate to a second sampling rate using a function based on said preferred number of measurements within a target zone, said predetermined critical threshold, said predetermined hypoglycemic threshold, and said actual rate of change in glucose concentration. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
