Mark R Robinson, Kenneth J Ward, Robert P Eaton, David M Haaland: Method of and apparatus for determining the similarity of a biological analyte from a model constructed from known biological fluids. University of New Mexico, Lowe Price LeBlanc Becker & Shur, December 4, 1990: US04975581 (384 worldwide citation)

The characteristics of a biological fluid sample having an analyte are determined from a model constructed from plural known biological fluid samples. The model is a function of the concentration of materials in the known fluid samples as a function of absorption of wideband infrared energy. The wid ...
