A urinal is provided on its forward end with a cell, which internally communicates with the urinal to outwardly project from the same. A measuring part comprises a light source part for applying a measuring beam of the visible or near infrared wavelength region to the cell which is set in a cell setting part and a light receiving part for receiving and detecting the measuring beam transmitted through the cell, and measures absorbances of uric components to be measured at wavelengths selected therefor respectively. A sensor part is adapted to detect that the cell is set in the cell setting part, so that the measuring part starts a measuring operation on the basis of a signal indicating that the sensor detects the cell. It is possible to carry out a urine test on a person who lies on bed.
