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.

A dual chamber, multi-analyte test strip has a first insulating layer, a first electrically conductive layer, with a first working electrode, disposed on the first insulating layer and a first patterned spacer layer positioned above the first electrically conductive layer. The first patterned spacer layer has a first sample-receiving chamber, with first and second end openings, defined therein that overlies the first working electrode. The test strip also includes a first counter/reference electrode layer that is exposed to the first sample receiving chamber and is in an opposing relationship to the first working electrode. The test strip further includes a counter/reference insulating layer disposed over the first counter/reference electrode layer and a second counter/reference electrode layer disposed on the counter/reference substrate. Also included in the test strip is a second patterned spacer layer that is positioned above the second counter/reference electrode layer. The second patterned spacer layer has a second sample-receiving chamber, with first and second end openings, defined therein. The test strip additionally has a second electrically conductive layer, with a second working electrode, disposed above the second patterned spacer layer, a second insulating layer disposed above the second electrically conductive layer, a first analyte reagent layer disposed on the first working electrode within the first sample-receiving chamber; and a second analyte reagent layer disposed on the second working electrode within the second sample-receiving chamber. The second counter/reference electrode layer is exposed to the second sample receiving chamber and is in an opposing relationship to the second working electrode.

An analytical test strip and test meter combination for use in the determination of an analyte in a bodily fluid sample includes an analytical test strip and a test meter, and a method for determination thereof. The analytical test strip has an electrode, a first electrical contact pad in electrical communication with the electrode and configured to communicate an electrical response of the electrode to the test meter; and a second electrical contact pad in electrical communication with the electrode and configured to communicate an electrical response of the electrode to the test meter should the test meter be in electrical communication with the second electrical contact pad. In addition, the second electrical contact pad has electrical continuity with the first electrical contact pad and the first and second electrical contact pads are disposed in either of first and second predetermined spatial relationships to one another.

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.
