An electrochemical test device is provided having a base layer with a first electrode thereon and a top layer with a second electrode thereon. The two electrodes are separated by a spacer layer having an opening therein, such that a sample-receiving space is defined with one electrode on the top surface, the other electrodes on the bottom surface and side walls formed from edges of the opening in the spacer. Reagents for performing the electrochemical reaction are deposited on one of the electrodes and on the side walls of the sample-receiving space. |
