Description

[0001] The present invention claims priority to U.S. Provisional Patent Application No. 60 / 183,356, filed Feb. 18, 2000, and titled "Multivariate Analysis of Green to Ultraviolet Spectra of Cell and Tissue Samples."

[0002] 1. Field of the Invention

[0003] This invention relates to analysis methodology and multivariate classification of diagnostic spectra, and, in particular, to methods for processing in vivo skin auto-fluorescence spectra for determining blood glucose levels. The invention also relates to methods of classifying cells or tissue samples or quantifying a component of a cell or tissue using a multivariate classification or quantification model.

[0004] 2. Description of the Background

[0005] Near-IR spectra taken from agricultural samples, such as grains, oil, seeds and feeds, etc., have been used to quantitate various bulk constituents, e.g., total protein, water content, or fat content. See, P. Williams et al., "Agricultural Applications of Near-IR Spectroscopy and PLS Pro...
