Abstract
Electrochemical sensors for investigating a physiological sample and methods of manufacture are disclosed. The sensor includes an electrochemical reaction cell, having electrodes and a reagent, and laterally spaced electrical contact points for electrically communication with a meter. Further described herein is a multi-chambered sensor having an electrochemical reaction cell and an immunological cell. The multi-chambered cell can also include a pre-chamber.
