Abstract
A calibration method for blood glucose of blood sample comprises the following steps: applying a first voltage to a blood sample to obtain an original level of blood glucose of the blood sample; applying a second voltage to a blood sample to obtain a hematocrit index of the blood sample; and processing the hematocrit index and calibrating the original level of blood glucose of the blood sample. The absolute value of the first voltage is lower than 1 volt and is not equal to 0 volt. The absolute value of the second voltage is higher than or equal to 1 volt. A sensing current corresponding to the original blood level and the hematocrit index corresponding to blood sample are obtained by applying at least two-stage voltages in the specific range to the blood sample, thereby calibrating the original blood glucose according to the hematocrit index.
