Abstract
An electrochemical test system comprising an electrochemical test strip capable of initiating an instrument, determining if it is inserted into a correct position of the instrument, a sample is injected into a reaction region of the electrochemical test strip, and the sample covers the reaction region properly. The electrochemical test strip includes an insulating substrate, an electrode system, and an insulating layer. The electrode system includes a resistor, a set of measurement electrodes which includes a reference electrode and a working electrode insulated from each other, and a set of identifying electrodes which includes first and second identifying electrodes connected through the resistor. A method for detecting a sample includes the steps of inserting the electrochemical test strip into a measurement instrument, providing the sample in the reaction region, and applying a voltage between the reference electrode and the working electrode, and measuring a current corresponding to the voltage.
