Abstract: This application relates to a self-reference point setting type blood component measuring method and apparatus using light. In one aspect, the method includes applying light to a skin of a subject to be measured and setting a reference point on a surface of the skin adjacent to a point at which the light is applied. The method further includes calculating a concentration of a blood component from a light intensity measured at the reference point and a light intensity measured at another point. According to some embodiments, the accuracy and precision of measurement are increased in measuring blood in a non-invasive manner.
