PROBLEM TO BE SOLVED: To provide a measuring apparatus and measuring method for optically measuring the variation of the blood plasma and the red blood cell of flowing blood.SOLUTION: The measuring apparatus includes: a light source for emitting a light flux from a direction substantially perpendicular to the flowing direction of blood; a light receiver for receiving the reflected light of the light flux; and a control device for processing an intensity signal received by the light receiver while controlling the light flux of the light source. The control device (1) acquires a first signal string that is received by the light receiver and is in a first wavelength region smaller than a predetermined wavelength, (2) acquires a second signal string that is received by the light receiver and is in a second wavelength region larger than the predetermined wavelength, and (3) acquires variation information of each of the blood plasma and red blood cell by correcting the second signal string with the first signal string. |
