AUTOMATED METHOD FOR READOUT OF TEST PIECE, AND TEST PIECE USED THEREFOR

PROBLEM TO BE SOLVED: To obtain an automated method in which the readout operation of a test piece comprising a test field and a marker field on its surface can be automated by correlating the sequence of a spectral reflectance reflected by the test field and the marker field at the test piece with information which is programmed in advance. SOLUTION: A test piece 22 which comprises one test field and a plurality of marker fields 504 on its surface is prepared. Then, the test piece 22 is introduced into a test-piece reader which is provided with a field readout means which contains a light source as a transmitter and a photosensitive element as a receiver, with a means by which the value of a spectral reflectance value in every specific spectral region of reflected light is correlated with information which is programmed in advance regarding the test piece 22 and with a means which is moved so as to be capable of reading out the reflectance. Then, the reflectance is read out. Then, the sequence of spectral reflectances measured from the marker fields 504 is transmitted to the correlation means so as to be correlated with the information which is programmed in advance regarding the test piece 22.
