Method and apparatus for measuring blood glucose concentration
Abstract
A non-invasive method for measuring blood glucose concentration using glucose present at the mucosal surface of a living being is provided. The method includes the steps of positioning a glucose oxidase membrane on the mucosal surface, providing oxygen for peroxidative oxidation of the glucose present thereat, electrically measuring the amount of hydrogen peroxide product and calibrating that amount to determine blood glucose concentration. Also provided are electrode devices suitable for carrying out the method.
