Patent ID: 8409424

Claim:
An electrochemical test strip, comprising: an insulating substrate; an electrode system formed on the insulating substrate, the electrode system comprising a set of measurement electrodes, a set of identifying electrodes and a resistive path having a predetermined resistance value, wherein the set of identifying electrodes is made of metal material and the resistive path is made of non-metal material, wherein the set of measurement electrodes comprises a reference electrode and a working electrode insulated from each other, and the set of identifying electrodes comprises a first identifying electrode and a second identifying electrode connected with each other through the resistive path; and an insulating layer covering a part of the electrode system, wherein a part of the electrode system not covered by the insulating layer forms a reaction region with a supply port; wherein when the sample is injected into the supply port of the reaction region, the sample reaches the set of measurement electrodes and the set of identifying electrodes in sequence.
