ELECTROCHEMICAL-BASED ANALYTICAL TEST STRIP WITH FILL-SPEED CONFIGURED REAGENT LAYER

摘要

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. In addition, the patterned insulation layer and the patterned spacer layer define a sample receiving chamber with a sample-receiving opening 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 working electrode and counter/reference electrode exposed portions and extends no more than 400µm toward the sample-receiving opening.
