TEST STRIP WITH STACKED UNIDIRECTIONAL CONTACT

摘要

An analytical test strip ('ATT') for use with a test meter includes a first insulating layer with a first insulating layer upper surface and a first electrically conductive layer ('ECL') disposed thereon. The first ECL includes a first electrode portion ('EP') and an electrical contact pad in electrical communication with the first EP. The ATT also includes a patterned spacer layer disposed above the first ECL that includes (i) a distal portion defining a bodily fluid sample receiving chamber therein that overlies the first EP and (ii) an insulating proximal portion with an upper surface having a second ECL disposed thereon. The second ECL includes an interlayer contact portion and an electrical contact pad. A third ECL of the ATT includes a second EP and a proximal portion that overlies the interlayer contact portion. The second EP is disposed overlying and exposed to the sample receiving chamber in an opposing relationship to the first EP.
