Abstract
Systems and methods for measuring analytes in fluid samples are disclosed. The systems and methods employ test strips which are generally comprised of a substrate, at least one electrical connection, at least one sensing chemistry and at least one additional layer. The test strips can be batch calibrated.
Claims21
A system for determining the concentration of at least one analyte in a fluid sample, the system comprising:
- a base substrate;
- a first electrode pair disposed over the substrate;
- a conversion chamber adapted for producing an altered analyte by oxidizing or reducing the at least one analyte in the fluid sample;
- an active sensing chemistry in electrical communication with the first electrode pair,
- wherein the active sensing chemistry is responsive to the altered analyte, and
- wherein the active sensing chemistry forms a chemical bond with the altered analyte, and
- a test strip chamber housing the sensing chemistry,
- wherein the test strip chamber is adapted to direct at least a portion of the altered analyte over the sensing chemistry.
