Abstract

A sensing member for detecting total cholesterol of a blood sample is disclosed, which includes: a working electrode and a counter electrode respectively formed on a first substrate and a second substrate, wherein, an opening is formed in one of the first and second substrates corresponding in position to the electrode for allowing the blood sample to pass through; a dielectric layer formed on one of the surfaces of the first and second substrates and exposing the electrode and end connector such that the end connector can be electrically connected to an electronic device used for applying electric voltage; a reactive pad disposed between the working electrode and the counter electrode and containing an reactive reagent, wherein the reactive reagent comprises an electron transport material, an enzyme capable of reacting with the analyte and generating a current corresponding to the concentration, and a buffer solution; and a separating pad disposed on the opening for removing interfering materials from the blood sample before the blood sample enters into the opening. By disposing the separating pad at a specified position, corpuscles and interfering giant molecules can be removed from the blood sample so as to quickly and accurately detect total cholesterol of the whole blood sample.
