Abstract: The present invention relates to a method and system for estimation of blood anylates, more particularly the invention relates to mitigation strategies for the confounding factors in the non-invasive estimation of blood anylates. The present invention is hypothesized to measured with an accuracy reasonable for an anemia screening tool through measurement of the following parameters Finger Size, Transmitted infrared light through the finger, Finger tip temperature.

Abstract: A system and method for measurement of absolute value of hemoglobin concentration non-invasively is provided. The system comprises a probe device comprising a sliding top structurally configured to be manually slid forward and backward onto the finger seat which is positioned on top of the housing for placing a fingertip. The finger seat houses two cavities for housing a set of three light emitting diodes and a photodetector respectively. Multiple distinct wavelengths of light transmitted through the fingertip is detected by the photodetector. Further, electronic signals generated by the photodetector are processed to obtain alternating and direct components of light corresponding to each wavelength. A system of three equations are obtained including unknown values of two primary constituent absorbers and known consolidated values of one or more secondary constituent absorbers corresponding to each wavelength of light.
