The present invention relates to a measurement method of an electrochemical biosensor that detects biomarkers contained in bodily fluids such as blood, urination, saliva as a measuring principle of electrochemical signals, and more specifically, time in an in vitro diagnostic device using an electrochemical biosensor. It relates to a measurement method of an electrochemical biosensor that can improve the accuracy and reproducibility of measurement in the measurement by the current method or the time charge method. According to the present invention, in measuring an electrochemical biosensor for measuring a biomarker by a time-current method or a time-charge method, the electrode is immersed in a measurement solution and a voltage is not applied to the electrode for a certain period of time, and then a charge value is measured or constant. There is an excellent effect that can improve the accuracy and reproducibility of the measurement by measuring the current value after applying the time voltage. |
