Disclosed is an automated method for reading a test strip for the analysis of one or more analyte in a liquid test sample. The method involves the spectrophotometric reading of a test strip which bears at least two marker fields on its surface which are capable of reflecting light at different spectral regions from each other. The reading means of the spectrophotometer is programmed to discern information concerning the strip, such as what analyte the strip is designed to detect, from the sequences of spectral classifications by spectral reflectancy measurements of the strip's marker fields.

[ I claim:] [1.] An automated method of reading a test strip for the analysis of one or more analyte(s) in a liquid test sample which comprises the steps of:a) providing a test strip having at least one test field on its surface which reflects light at a specific range of wavelengths and at least two distinct marker fields on the same side of its surface as the test field which marker fields reflect light at different ranges of wavelengths from each other and from the test field in a coded sequence of ranges of wavelengths which coded sequence correlates to information concerning identification of the test strip;b) introducing the test strip into a strip reading device equipped with reading means for both of the test and marker fields which reading means comprises a light source as transmitter and a light sensitive element as receiver which receiver is capable of differentiating between the ranges of wavelengths at which the marker and test fields reflect, which strip reading device is also equipped with means for correlating the coded range of wavelength sequence of reflected light with preprogrammed information concerning the test strip which correlating means is in operative communication with the receiving means and which reading device has means for moving the strip and receiving means relative to one another, so that the reflectance of the test field and marker fields can be individually read by the reading means;c) allowing range of wavelength values reflected by the test and marker fields to be individually read by the reading means; andd) allowing the reading means to communicate the sequence of spectral reflectance values reflected from the marker fields to the correlating means and allowing the correlating means to correlate the sequence of reflected range of wavelength values with the preprogrammed information concerning the strip.
