Electrochemical test strip cards that include an integral dessicant

A method of fabrication an electrochemical test strip card comprising a plurality of test strips configured to be singulated from said test strip card, said method comprising:

• providing a top electrode layer, a bottom electrode layer and a spacer layer therebetween, wherein said spacer layer comprises a pattern that provides for at least a fluid ingress channel, a reaction chamber, a location for a desiccant chamber, a channel interconnecting said reaction chamber and said location for a desiccant chamber, and a venting channel;
• laminating together said top layer, said bottom layer and said spacer layer;
• punching a hole through said laminated structure at said desiccant chamber location thereby forming a desiccant chamber;
• positioning a desiccant material in said desiccant chamber;
• and
• providing a first barrier layer on top of said laminated structure and a second barrier layer on the bottom of said laminated structure wherein said descant chamber is in gaseous communication with said reaction chamber.
