Abstract:
1. An electrochemical test strip capable of testing injection condition of a sample, the electrochemical test strip comprising: an insulating substrate; an electrode system formed on the insulating substrate, the electrode system including a set of measurement electrodes, a set of identifying electrodes and a resistor having a predetermined resistance value, 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 resistor; 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.
