ABSTRACT:
Systems and methods for non-invasive blood analysis are disclosed in which blood is illuminated at a plurality of discrete wavelengths selected from the near infrared spectrum. Measurements of the intensity of reflected or transmitted light at such wavelengths are taken, and an analysis of reflectance or transmittance ratios for various wavelengths is performed. Changes in the ratios can be correlated with specific material properties, such as the concentration of cholesterol in a subject's circulatory system.
