Method of making sensor
First Claim
1. A method of making a testing device for testing a fluid sample comprising the steps of:
- positioning at least two spaced apart electrically conductive electrodes in a mold;
molding a body within the mold of insulative material to at least embed a part of the electrodes in the insulative material and to permit exposure of at least a portion of one electrode to a fluid sample to be tested; and
, treating at least one of the electrodes with one or more substances before or after the molding of the body for reacting with the fluid sample to be tested.

Abstract
A sensor is provided for the determination of various concentrations of one or more components within a fluid sample. The sensor includes an injection molded body, at least two electrodes, an enzyme, and if desired, an electron transfer mediator. The body includes a reaction zone for receiving a fluid sample. The electrodes are at least partially embedded within the plastic body and extend into the reaction zone. Also contained within the reaction zone is an enzyme capable of catalyzing a reaction involving a compound within the fluid sample. Additionally, the sensor incorporates fill detection which activates a meter, attached to the sensor, for measuring the electrochemical changes occurring in the reaction zone.
