Abstract: Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is made up of four protein molecules (globulin chains) that are connected together. The normal adult hemoglobin (Hbg) molecule contains two alpha-globulin chains and two beta-globulin chains. Hemoglobin is usually measured as a part of the complete blood count (CBC) test from a blood sample. There are several invasive methods for determining Hb concentration. Invasive methods include clinical examination and referencing the colour of a drop of blood on filter paper to a standardized colour comparison chart. Here is an attempt to design a system for non-invasive hemoglobin monitoring . A total description of setup for non-invasive hemoglobin monitoring using near infrared is presented. It includes projection of near infrared radiation on a figure of subject and sensing the resultant radiation after absorbance by hemoglobin .Here the hemoglobin count is attributed to the voltage level which are standardized through a series of experiment and analysis
