Blood glucose meters must comply with GB 9706.1, YY 0505 (domestic) and IEC 60601-1-2 (international) EMC standards, and are also considered home-use devices. They use an electrochemical (current method) method to measure the minute current (μA level) generated by the reaction of blood glucose on the test strip. The standards require that this weak current measurement be accurate and unaffected by static electricity introduced during user operation, environmental radio frequency interference (e.g., mobile phones), and internal circuit noise, ensuring accurate and reliable readings, which is crucial for self-management of diabetes.
