A multi-analyte test strip includes a first insulating layer and an electrically conductive layer disposed on the first insulating layer. The electrically conductive layer has a first working electrode with a first analyte contact pad, a shared counter/reference electrode with a counter/reference electrode contact pad, and a second working electrode with a second analyte contact pad. The multi-analyte test strip also includes a second insulating layer disposed above the first insulating layer and a patterned spacer layer positioned between the first insulating layer and the first electrically conductive layer with the patterned spacer layer defining a bodily fluid sample-receiving chamber that overlies the first working electrode, the shared counter/reference electrode and the second working electrode. The multi-analyte test strip further includes a mediator reagent layer disposed over the first working electrode, the shared counter/reference electrode and the second working electrode; a first analyte reagent layer disposed over the first working electrode and mediator reagent layer; and a second analyte reagent layer disposed over the second working electrode and mediator reagent layer. Furthermore, the first analyte electrode, shared counter/reference electrode and second analyte electrode of the multi-analyte test strip are disposed on the first insulating layer in a planar inline configuration.
