Dual-chamber analytical test strip

摘要

An analytical test strip can include a patterned definition layer defining two fluidically-separated sample cells having respective ports, a common electrode arranged over the definition layer and in electrical communication with each of the cells, and respective cell electrodes. Surface portions of each electrode can be exposed. A method for testing a fluid sample using such a strip includes receiving a first fluid sample in the first sample cell and detecting a first electrical property thereof. It is then determined whether a second fluid sample should be added to the other sample cell. An analyte measurement system can include such a strip and test meter to receive the strip. The test meter can detect respective electrical properties of fluid samples in the cells.

1. An analytical test strip, comprising:
a patterned definition layer defining two fluidically separated sample cells, each sample cell having a port on a perimeter of the analytical test strip and being adapted to receive a respective fluid sample via the respective port; a common electrode arranged over the definition layer and in electrical communication with each of the sample cells; and two cell electrodes, each electrode in electrical communication with a respective one of the sample cells; wherein the definition layer, the common electrode, and the cell electrodes are arranged to expose a surface portion of the common electrode and respective surface portions of the cell electrodes.
