Measurement of Hemoglobin (Hb) in blood using photo detector by reflection method

M. P. Patil, T. N. Ghorude

Abstract :

 The detection of blood Hemoglobin using own developed, compact & cost–effective device containing optical sensors by reflectometry is aimed in the work. Hemoglobin is a protein in red blood cells, which carries oxygen throughout our body. The low Hb count may indicate anemia, which is a severe nutritional disease. The device is developed using light sensor & RED LED with specific circuit designing. The blood sample is illuminated by RED LED using the 45⁰/0⁰ geometry. The RED light is illuminated on the sample at an angle of 45⁰ from the perpendicular to the sample surface. The light sensor (detector–L14G3) receives the reflected light at a location 0⁰ from the perpendicular to the sample. Using the linear interpolation method, the hemoglobin value is determined and the results are compared with the Hemochek^TM validated color scale approved by WHO with the range from 4 gm/dl to 14 gm/dl. From the values obtained, the status of anemia can be known. The results are also compared with pathology lab measurements and found in good agreement.
