Abstract

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.

Claims

1. A test meter for use with a dual-chamber, multi-analyte test strip, the test meter comprising:

a test strip receiving module with;

a first electrical connector configured for contacting a first analyte contact pad of a first working electrode of the dual-chamber, multi-analyte test strip;

a second electrical connector configured for contacting a second analyte contact pad of a second working electrode of the dual-chamber, multi-analyte test strip

a third electrical connector configured for contacting a first counter/reference contact pad of a first counter/reference electrode layer of the dual-chamber, multi-analyte 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 dual-chamber, multi-analyte test strip; and

a signal processing module,

wherein 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 in a bodily fluid sample applied to the dual-chamber, multi-analyte test strip; and

wherein 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 in the bodily fluid sample applied to the dual-chamber, multi-analyte test strip, and

wherein the third electrical connector is configured to contact the first counter/reference contact pad in an opposing manner with respect to the contact of the fourth electrical connector and the second counter/reference contact pad.

2. The test meter of claim 1 wherein first electrical connector is configured to contact the first analyte contact pad in an opposing manner with respect to the contact of the second electrical connector with the second analyte contact pad.

3. The test meter of claim 1 wherein the first analyte is non-identical in comparison to the second analyte.

4. The test meter of claim 3 wherein the first analyte is glucose.

5. The test meter of claim 4 wherein the second analyte is a ketone.

6. The test meter of claim 5 wherein the ketone is 3-hydroxybutyrate.

7. The test meter of claim 1 wherein the bodily fluid sample is a whole blood sample.

8. The test meter of claim 1 wherein the signal processing module is configured for determination of the first analyte and determination of the second analyte via an electrochemical-based determination technique.

9. The test meter of claim 1 wherein the signal processing module is configured to receive the first signal and the second signal in a sequential manner.

10. The test meter of claim 1 wherein the signal processing module is configured to receive the first signal and the second signal in a simultaneous manner.
