Abstract
A method, apparatus and procedure for the non-invasive detection of the sugar concentration changes in body liquids such as blood is disclosed. The instrument measures sugar concentration changes using the natural fingerprint of sugar which is rotations of polarization of light emitted from the biological particle chromophores dissolved together with sugar in human liquids. The degree of polarization of light emitted from luminescence centers undergoing interaction with an optically active medium such as sugar is proportional to the concentration of sugar in, for example, blood. The reference level is determined by conventional blood analysis using standard monitoring equipment during the special procedure of the Glucose Tolerance Test.
