Summary:An improved electrochemical sensor having a base bearing a working and counter electrode which provides a flow path for a fluid test sample. The working and counter electrodes are configured so that a major portion of the counter electrode is located downstream on the flow path from the working electrode with the exception of a small sub-element of the counter electrode which is in electrical communication with the primary portion of the counter electrode and located upstream of the working electrode. This configuration enables the sensor when the capillary space is incompletely filled with test fluid.
