The electrochemical test strip includes an insulating substrate, an electrode system formed on the insulating substrate, and an insulating layer formed on the electrode system. The electrode system includes a set of measurement electrodes, a set of identifying electrodes, and a resistive path having a predetermined resistance value. The set of identifying electrodes is made of metal material, and the resistive path is made of non-metal material. The set of measurement electrodes includes a reference electrode and a working electrode insulated from each other, and the set of identifying electrodes includes a first identifying electrode and a second identifying electrode connected with each other through the resistive path. The insulating layer covers 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. When a sample is injected into the supply port of the reaction region, the injected sample reaches the set of measurement electrodes and the set of identifying electrodes in sequence.

摘要:
A reaction cassette for biochemical assay, a biochemical assay device including the reaction cassette, and a biochemical assay method performed by using the biochemical assay device are provided. The reaction cassette includes a first space, a second space, a third space, and an inner wall. The first space is configured to accommodate liquid and includes a first opening facing upward. The second space includes a second opening whose direction is perpendicular to the direction of the first opening. The first space and the second space are disposed such that when the reaction cassette is rotated, liquid in the first space can flow into the second space. The third space is located under the first space and includes a third opening whose direction is the same as the direction of the first opening. The inner wall connects the second opening and the third opening, which serves as a liquid flow channel between the second space and the third space.
