Abstract
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.
