Individual calibration of blood glucose for supporting noninvasive self-monitoring blood glucose
First Claim
1. A method of calibrating a noninvasive glucose monitor for prospective noninvasive glucose determination, comprising the steps of:
- measuring spectroscopic transflectance readings of a patient'"'"'s skin using a noninvasive glucose monitor;
measuring the patient'"'"'s blood glucose level with an invasive glucose monitor;
correlating the noninvasive and invasive measurements to form an individual algorithm for the patient; and
spatially adjusting a position of the patient'"'"'s skin with respect to a probe of the noninvasive glucose monitor while collecting transflectance measurements such that multiple readings are taken over a relatively large area of the patient'"'"'s skin.

Abstract
A method is provided for calibrating a noninvasive glucose monitor for prospective noninvasive glucose determination. Spectroscopic transflectance readings are measured on the patient'"'"'s skin using a noninvasive glucose monitor. The patient'"'"'s blood glucose level is measured with an invasive glucose monitor. The noninvasive and invasive measurements are correlated to form an individual algorithm for each patient. Preferably, the position of the patient'"'"'s skin with respect to the probe of the noninvasive monitor is spatially adjusted while collecting the transflectance measurements such that multiple readings are taken on the patient'"'"'s skin. The measurements are preferably taken over a period of time and over a plurality of glucose levels in the patient.
