ABSTRACT:
A method for detecting a component of a biological system, which comprises contacting a biological component detecting device composed of a light reflecting substrate (I) substantially free from diffused reflection, a light interference layer (II) formed on the substrate (I), and a layer (III) of a substance for detecting said biological component provided at least in a region on the layer (II), with a solution presumed to contain the biological component to be detected, then forming a light-transmitting reflecting layer (IV) on its surface, and thereafter detecting the color of light interference or the brightness of the reflected light on the surface of the device.
