Abstract:
1. A measuring method using an electrochemical biosensor measuring device and an electrochemical biosensor, wherein the biosensor is composed of a plurality of electrodes including at least a working electrode and an auxiliary electrode prepared on at least one or two insulating plates; a capillary sample cell for introducing a sample into the electrodes; a reaction reagent layer, formed on the working electrode, containing a redox enzyme and an electron transfer mediator; an electrical connection portion for connecting the working electrode and the auxiliary electrode; and a production lot information identification portion configured such that production lot information is recorded on at least one insulating plate, which is selected from among at least two planar insulating plates and does not interrupt a connection between the electrodes, wherein the production lot information identification portion includes one or more hue marks displaying the information about differences between production lots attributable to differences in color, brightness, or chroma, wherein the electrochemical biosensor measuring device comprises a connector having a connector port, at least two light emitters of which each emits a different color and a detector for sensing the emitted light, and the method comprising: inserting the biosensor into the connector port of the biosensor measuring device to activate its power (step 1); identifying the production lot information of the inserted biosensor by allowing said at least two light emitters to emit light beams having different wavelengths in a sequential manner at the production lot information identification portion and detecting the light beams with the production lot information identification portion provided in the biosensor (step 2), wherein the light beams emitted from the light emitters are sequentially detected by the detector without using a separate filter; activating the measurement and operation processes of the biosensor measuring device in conformity with the production lot information identified at Step 2 (step 3); and introducing a liquid sample to the sample inlet of the biosensor to result in quantitative electrochemical information about the sample, quantifying a specific component of the liquid sample, and displaying quantification results (step 4).
