Abstract
An electrochemical test sensor includes a lid and a base. The base has a length and a width. The length of the base is greater than the width of the base. The base includes at least a working electrode, a counter electrode and at least three test-sensor contacts for electrically connecting to a meter. The at least three test-sensor contacts are spaced along the length of the base from each other. The base and the lid assist in forming a fluid chamber for receiving the fluid sample. The electrochemical test sensor further includes a reagent to assist in determining the concentration of the analyte in the fluid sample.
