1. A multi-use assay system comprising:

  • an electronics printed circuit board;

    an optics system comprising a lens, an emitter, and a detector, wherein the emitter and detector are mounted in the electronics printed circuit board;

    a removable test strip for alignment to the optics system by means of center line fixturing;

    a housing for containing the optics system and holding the removable test strip in position relative to the optics system;

    a test pad having a center line;

    an optics block holder keyed to align the removable test strip to the center line of the test pad and to mount in the electronics printed circuit board such that the optics block holder aligns to alignment fixturing of an emitter and detector placement machine, the optics block holder positioning the optics system to focus the light from the emitter and to the detector;

    a processor for processing data from the emitter and detector; and

    a removable single use electronic calibration system for providing the processor with strip specific calibration information.
