Anemia is a major health concern in developing countries. Hemoglobin level assessment can be a reliable source of estimation of anemia. There are several invasive and non-invasive techniques available for determination of hemoglobin level. In this paper we are mainly focusing on invasive techniques based on image, diffuse reflectance spectroscopy, Optoacoustic Method and Photo-plethysmography. From this study we found that image based techniques hold better scope in determination of hemoglobin concentration and to improve the success rate of existing methods work must be done on ambient lighting condition.
