An electrochemical-based analytical test strip includes an electrically-insulating substrate, a patterned conductive layer disposed over the electrically-insulating substrate, a patterned insulating layer disposed over the patterned conductive layer, an enzymatic reagent layer disposed over the patterned conductive layer, a patterned adhesive layer disposed above the enzymatic reagent layer and a top layer disposed over the enzymatic reagent layer. In addition, the test strip has a sample-receiving chamber defined by the electrically-insulating substrate, the patterned conductive layer, the patterned insulating layer, the enzymatic reagent layer, the patterned adhesive layer and the top layer. The sample receiving chamber of the test strip has a working portion and a non-working portion and the top layer has a first portion and an opaque second portion. The first portion is configured such that a user can view the working portion of the sample-receiving chamber through the first portion of the top layer, while the opaque second portion is configured to preclude a user from viewing the non-working portion of the sample-receiving chamber.
