ABSTRACT:
The invention provides an optical method and apparatus for non-invasively determining blood hematocrit. The method includes the step of first irradiating blood with optical radiation. Radiation reflected or transmitted from the blood is then collected to determine an optical spectrum. Hematocrit is then determined by comparing this spectrum to a mathematical model relating optical properties to blood Hematocrit.
