Abstract:
1. A method of controlling sample site disparity error in calibration of a noninvasive glucose analyzer comprising: collecting one or more noninvasive signals from a subject's body at an alternative sampling site, said alternative sampling site having a location that is among those sites that are selected when performing an alternative invasive glucose determination, said alternative sampling site being located at a region other than said subject's fingertips or toes; invasively determining an alternative reference glucose measurement corresponding in time to each noninvasive signal from said body at an alternative reference measurement site, said alternative reference measurement site located at a region of the body having a tissue matrix substantially identical or equivalent to a tissue matrix at said alternative sampling site so that error due to a discrepancy between glucose concentration at said alternative sampling site and said alternative reference measurement site is reduced or eliminated, and; any of the steps of:
