Electrochemical method: the electrons generated by the reaction between enzyme and glucose are read by current counting facilities, and then converted into glucose concentration readings. A small amount of blood samples are required for measurement, with high accuracy. Moreover, the blood glucose meter using electrochemical method can avoid pollution, and the error range is plus or minus 0.2. Under normal use, there is no need to calibrate.

The electrochemical law will not be disturbed by Hyperlipidemia and hyperbilirubinemia, but the microwave oven and mobile phone in use will affect the accuracy of the instrument; Therefore, when using this kind of instrument for blood glucose monitoring, the instrument should be protected from electromagnetic radiation. The latest principle of blood glucose meter has adopted electrochemical principle and blood suction blood collection. It has very high accuracy and is also very convenient to use. It is very suitable for daily monitoring blood glucose.
