Abstract: An analytical test strip for the determination of an analyte (such as glucose) in a bodily fluid sample (e.g., a whole blood sample) includes a first and second capillary sample-receiving chambers and first and second stop junctions that are disposed between the first and second capillary sample-receiving chambers. The first stop junction defines a discontinuity boundary of the first capillary sample-receiving chamber and the second stop junction defines a discontinuity boundary of the second capillary sample-receiving chamber. In addition, the first stop junction and the second stop junction are disposed such that bodily fluid sample flow between the first capillary sample-receiving chamber and the second capillary sample-receiving chamber during use of the analytical test strip is prevented.

Abstract: An electrochemical-based analytical test strip (“EBAT”) for the determination of an analyte in a bodily fluid sample includes an electrically insulating substrate layer with a distal end and a patterned conductor layer that is disposed over the electrically-insulating substrate layer and has a working electrode (“WE”) and a counter/reference electrode (“C/RE”). The EBAT also includes a patterned insulation layer with an electrode exposure window configured to expose a WE exposed portion and a C/RE exposed portion, an enzymatic reagent layer; and a patterned spacer layer. The patterned insulation layer and the patterned spacer layer define a sample receiving chamber with a sample-receiving opening (“SRO”) at the distal end of the electrically insulating substrate layer and that extends across the WE exposed portion and the C/RE exposed portion. Furthermore, the enzymatic reagent layer is disposed over the WE and C/RE exposed portions and extends no more than 400 ?m toward the SRO.

Abstract: An analytical test strip (“ATS”) for use with a hand-held test meter in the determination of an analyte in a bodily fluid sample includes an electrically insulting substrate, a first patterned conductor layer disposed on the electrically insulating substrate and having a working electrode and a reference electrode. The ATS also includes an enzymatic reagent layer disposed on the working electrode, a first patterned spacer layer disposed over the first patterned conductor layer and defining both a first sample-receiving channel and an analyte determination sample chamber within the ATS, and a second patterned spacer layer disposed over the first patterned spacer layer and defining at least a second sample-receiving channel. The ATS further includes a bodily fluid phase-shift sample chamber in fluidic communication with the second sample-receiving channel.
