Abstract
Early and fast analyses of some clinical symptoms and signs of patients are of important for early diagnosis of some diseases, especially that it is related with blood discomfort i.e. anemia and polycythemia. Therefore, investigation a new methods and techniques for direct measurement, applicable, flexible, easy to use and cheap tool will facilitate in this manner. This article is aimed to enhance the ability of low power laser radiation alone to use as a biosensor in combination with photocell (transducer) and power meter (detector) without introducing any dye (analyte) to help in some clinical diagnosis. The absorption of laser radiation according to the absorption coefficient of blood was depended to detect the concentration of Hemoglobin (Hb) content in human blood. We used diode laser with wavelength 650 nm with low power 1m W. Finally, ANOVA table was used for results analysis.
