Glucose measurement utilizing non-invasive assessment methods
First Claim
1. A method for non-invasively determining the concentration of glucose in blood of a subject comprising the steps of:
- removing glucose from a skin surface;
allowing glucose to accumulate on the skin surface over a period of time, wherein the level is correlateable to the level of glucose within the blood;
measuring the level of glucose that has accumulated on the skin surface;
correlating the level of glucose to the level of glucose within the blood by using predetermined calibration data obtained by analysis of the subject'"'"'s blood.

Abstract
This involves non-invasive glucose measurement processes for determining blood glucose level in the human body. After achieving a static level of glucose at a surface of the skin over some period of time, the glucose may then be measured by a variety of different processes. A sample of the glucose may also first be extracted from the skin and this sample may then be measured. Clearly, these processes are especially suitable for monitoring glucose levels in the human body, and is especially beneficial to users having diabetes mellitus. These procedures may be used for other analyte materials that are found in appropriate regions of the outer skin.

12. A method for calibrating a non-invasive device for determining the concentration of glucose in a subject'"'"'s blood comprising the steps of:
-
removing glucose from a surface of skin; allowing glucose to accumulate on the skin surface over a period of time; measuring the level of glucose that has accumulated on the skin surface; comparing the measured level of glucose to a level obtained by a blood sample glucose determination; adjusting the measured level of glucose so that the level is correlated to the level of glucose obtained by the blood sample glucose determination. - View Dependent Claims (13, 14, 15)
