A detection module and a method for operating the same are revealed. A nano-scale iridium oxide membrane is used as a detection film. After being in contact with different concentrations of hydrogen peroxide, the iridium oxide membrane is oxidized or reduced to generate iridium (III) ions (Ir.sup.3+) or iridium (IV) ions (Ir.sup.4+). Thus a voltage shift is generated. Whether hydrogen peroxide is contained in the sample can be checked by detection of changes in the voltage. A sample is formed by mixing serum and benzylamine. When the serum in the sample contains LOXL2 enzyme associated with breast cancer, the LOXL2 enzyme reacts with benzylamine to get hydrogen peroxide which is used as a detection medium.
