20090046286Cancer detection by optical analysis of body fluids - The optical analysis of body fluids is a method of determining the relative concentration of certain bio-molecules in blood and urine samples by fluorescent spectroscopy. The relative concentration of these bio-molecules serves as a marker or screening test to assess the presence and stage of cancer in some organ or tissue of the body, and in some cases, the presence of particular types of cancer in the body. The bio-molecules include various species of porphyrin, flavins (including flavin mononucleotide[FMN], flavin adeno dinucleotide [FAD], and riboflavin), bile components (including biliverdin and bilirubin), tyrosine, tryptophan, and NAD(P)H. The fluorescent spectroscopy techniques include determining intensity maxima in the emission spectra at particular excitation wavelengths characteristic of the bio-molecules, determining intensity maxima in the excitation spectra at particular emission wavelengths characteristic of the bio-molecules, and synchronous scanning of the excitation and emission spectra while maintaining particular offsets in the wavelengths.02-19-2009
