摘要： An electrochemical-based analytical test strip for the determination of an analyte (e.g., glucose) in a bodily fluid sample (such as a whole blood sample) includes an electrically insulating base layer and a patterned conductor layer (for example, a gold patterned conductor layer) disposed over the electrically-insulating layer. The patterned conductor layer includes at least one electrode with the electrode having electrochemically inert areas and an electrochemically active area(s). Moreover, the electrochemically inert areas and electrochemically active area(s) are of a predetermined size and a predetermined distribution such that electrochemical response of the electrode during use of the electrochemical-based analytical test strip is essentially equivalent to a predetermined electrochemical response.

摘要： A test meter for use with a dual-chamber, multi-analyte test strip includes a test strip receiving module and a signal processing module. The test strip receiving module has a first electrical connector configured for contacting a first analyte contact pad of a first working electrode of the test strip; a second electrical connector configured for contacting a second analyte contact pad of a second working electrode of the test strip, a third electrical connector configured for contacting a first counter/reference contact pad of a first counter/reference electrode layer of the test strip, and a fourth electrical connector configured for contacting a second counter/reference contact pad of a second counter/reference electrode layer of the test strip. The signal processing module is configured to receive a first signal via the first electrical connector and the third electrical connector and employ the first signal for the determination of a first analyte (such as glucose) in a bodily fluid sample (for example, whole blood sample) applied to the dual-chamber, multi-analyte test strip. Moreover, the signal processing module is also configured to receive a second signal via the second electrical connector and fourth electrical connector and employ the second signal for the determination of a second analyte (e.g., a ketone analyte) in the bodily fluid sample applied to the dual-chamber, multi-analyte test strip. Furthermore, the third and fourth electrical contacts provide contact in an opposing manner.
