Abstract
An electrochemical-based analytical test strip for the determination of an analyte (e.g., glucose) in a bodily fluid sample (such as a whole blood sample) includes an electrically insulating base layer and a patterned conductor layer (for example, a gold patterned conductor layer) disposed over the electrically-insulating layer. The patterned conductor layer includes at least one electrode with the electrode having electrochemically inert areas and an electrochemically active area(s). Moreover, the electrochemically inert areas and electrochemically active area(s) are of a predetermined size and a predetermined distribution such that electrochemical response of the electrode during use of the electrochemical-based analytical test strip is essentially equivalent to a predetermined electrochemical response.
