Abstract
An analyte meter with a test strip port that detects an orientation of a test strip inserted therein. A control circuit of the test meter is configured to apply a first predetermined analyte measurement signal to a test strip electrode in response to detecting a first orientation of the test strip, and a second predetermined analyte measurement signal to the same, or a different, electrode in response to detecting a second orientation of the test strip.

21. A test strip comprising:
-
a planar, elongated substrate, said test strip having a first side and an opposing second side, said substrate further including a first end and an opposite second end; a sample chamber disposed between the first end and the second end, the sample chamber for receiving a sample applied thereto; and a plurality of electrodes configured to drive an analyte measurement current through the sample applied to the test strip, a first electrode disposed on the first side proximate the first end of the test strip, a second electrode disposed on the first side proximate the second end of the test strip, a third electrode disposed on the second side proximate the first end of the test strip, and a fourth electrode disposed on the second side proximate the second end of the test strip.

29. A test strip and strip port connector (SPC) system comprising:
-
a test strip with a lug disposed on a longitudinal edge thereof; and a strip port connector (SPC) including; a first set of electrical contacts configured to make operable contact with electrical contact pads of the test strip inserted into the SPC in a first orientation; a second set of electrical contacts configured to make operable contact with the electrical contact pads of the test strip inserted into the SPC in a second orientation; and a test strip orientation detection mechanism configured to distinguish the first and second orientations based on positioning of the lug in the SPC.

30. A method for employing a hand-held test meter with a test strip comprising:
-
inserting the test strip into an strip port connector (SPC) of a hand-held meter, the test strip having a lug disposed on a longitudinal edge thereof; making electrical contact to contact pads of the test strip using one of; a first set of electrical contacts configured to make operable contact with electrical contact pads of the test strip inserted into the SPC in a first orientation; and a second set of electrical contacts configured to make operable contact with the electrical contact pads of the test strip inserted into the SPC in a second orientation; and distinguishing the first and second orientations based on positioning of the lug in the SPC using a test strip orientation mechanism of the SPC.
