| description | An electrochemical-based analytical test strip ("TS") for the determination of an analyte in a bodily fluid sample includes an electrically insulating substrate, a patterned conductor layer disposed over the electrically-insulating substrate and having an analyte working electrode ("WE"), a bare interferent electrode ("IE") and a shared counter/reference electrode ("CE"). The TS also includes a patterned insulation layer ("PIL") with an electrode exposure slot configured to expose the WE, IE and CE, an enzymatic reagent layer disposed on the WE and CE, and a patterned spacer layer ("PSL"). The PIL and the PSL define a sample receiving chamber with a sample-receiving opening. The IE and the CE constitute a first electrode pair configured for measurement of an interferent electrochemical response and the WE and the CE constitute a second electrode pair configured for measurement of an analyte electrochemical response. The WE and the IE are electrically isolated from one another. |
