1. A method for electrochemically measuring a hematocrit value of a blood sample, the method comprising:

  • applying a voltage across a working electrode and a counter electrode in contact with the blood sample while an oxidant of a redox substance is in contact with the counter electrode and is not substantially in contact with the working electrode;

    detecting a resulting current flowing between the working electrode and the counter electrode; and

    calculating a hematocrit value of the blood sample based on the current,wherein at least part of a surface of the working electrode is in contact with the blood sample and is composed of a material including metal that readily undergoes electrolytic oxidation,wherein the voltage applied across the working electrode and the counter electrode causes reduction of the oxidant and oxidation of the metal that readily undergoes electrolytic oxidation, andwherein the current is detected by measuring a current that results from the oxidation and the reduction.
