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.

A system for the determination of an analyte in a bodily fluid sample includes an analytical test strip and an analytical meter. The analytical test strip has a substrate layer, an electroluminescent component (either an electroluminescent module and/or an electroluminescent lamp) disposed on the substrate layer, and a sample chamber configured for receiving a bodily fluid sample disposed above the substrate layer. Moreover, the analytical meter is configured for insertion of the analytical test strip therein and subsequent determination of the analyte.
