Abstract
The present invention provides a method of electrochemically measuring a hematocrit (Hct) value using a sensor, capable of achieving excellent measurement accuracy and reliability and also provides a sensor used in the method. The method of electrochemically measuring a hematocrit (Hct) value of blood include: providing an electrode system having a working electrode () and a counter electrode (), in which a redox substance is provided on the counter electrode () but not on the working electrode (); supplying blood to the electrode system; applying a voltage to the electrode system in this state to cause an oxidation current or a reduction current to flow between the working electrode () and the counter electrode (); detecting the oxidation current or the reduction current; and determining a Hct value based on a value of the detected current.
