1. Disposable apparatus for conducting patient testing and permitting multiple, two-point calibrated, test sequences, said apparatus comprising:

  • a disposable, sensing module havinga sample receiving and analyzing station includinga sample condition sensing electrode array operable to sequentially process a plurality of test sequences;

    a calibration fluid connecting station, integral with said sensing module, for detachable connection toa first calibration fluid source; and

    a second calibration fluid source;

    an analyte connecting station, integral with said sensing module, for detachable connection to an analyte source;

    a flow passage network operable to sequentially transmit to said electrode array a test sequence set includingan amount of a first calibration fluid from said first calibration fluid source;

    an analyte from said analyte source; and

    an amount of a second calibration fluid from said second calibration fluid source;

    a sample and calibration fluid receiving chamber integral with said sensing module, said chamber beingwholly internal of said sensing module,operable to receive and contain a plurality of said test sequence sets, andin continuous communication with said analyzing station;

    said sensing module and integral sample and calibration fluid receiving chamber being separable from said first and second calibration fluid sources and disposable separately therefrom;

    a first calibration fluid source detachably connected with said calibration fluid connecting station of said sensing module, withsaid first calibration fluid source being separable from said sensing modulesaid sensing module being disposable separately from said first calibration fluid source andsaid first calibration fluid source being disposed externally of said sensing module;

    a second calibration fluid source detachably connected with said calibration fluid connecting station of said sensing module, withsaid second calibration fluid source being separate from said first calibration fluid source,said second calibration fluid source being separable from said sensing module,said sensing module being disposable separately from said second calibration fluid source, andsaid second calibration fluid source being disposed externally of said sensing module;

    said calibration fluid connecting station being disposed separately from and operably independent of, said analyte connecting station, withsaid calibration fluid connecting station being operable to receive calibration fluid from each of said first and second calibration fluid sources independent of said analyte connecting station; and

    each of said first and second calibration fluid sources being disposed externally of, and separable from, said sensing module and integral sample and calibration fluid receiving chamber.
