Patent ID: 8409503

Claim:
A coloration analyzing apparatus for performing an analysis of a coloration state of a test piece provided with an insoluble support, through which a test body solution is developed, and a test region, which is formed on the insoluble support, the test region reacting with an analyte contained in the test body solution and undergoing coloration as a result of the reaction, the apparatus comprising: i) viscosity detecting means for detecting viscosity of the test body solution, which has been spotted onto the test piece, ii) washing liquid feeding means for feeding a washing liquid, which is used for washing the test region and its neighboring regions, to the test piece at the time between a stage, at which the test body solution has been developed through the test region, and a stage, at which an amplifying liquid for amplifying the coloration state of the test region is fed to the test piece, and iii) washing control means for controlling the washing liquid feeding means such that the quantity of the washing liquid fed to the test piece is set to be large as the viscosity of the test body solution, which viscosity has been detected by the viscosity detecting means, becomes high.
