Abstract
A reagent analyzer and method is described. In the method, a reagent card having a reagent pad is passed through an optical signal path between an optical signal source and an optical signal detector. A transition between a first electrical signal and a second electrical signal is detected to determine a substantially exact position of a leading end or a trailing end of the reagent pad. The first electrical signal is indicative of the substrate interfering with the optical signal. The second electrical signal is indicative of the substrate and reagent pad of the reagent card interfering with the optical signal. The reagent pad is moved to a known second location upon determining the substantially exact position of at least one of the leading end and the trailing end of the reagent pad. At the second location a sample is dispensed onto the reagent pad by a sample dispenser.
