Abstract

A technology and sensor chip that enable hematocrit levels in blood samples to be measured in a short time and at low cost are provided. A response current which is obtained by sweeping a voltage applied between a measurement working electrode and a measurement counter electrode provided to a sensor chip is measured and a hematocrit level is derived on the basis of the ability to track the response current with respect to temporal changes in the applied voltage that was swept. The hematocrit level in a blood sample can thus be measured in a short time without having to wait until a redox reaction in a redox substance for measuring the hematocrit level stabilizes as in the hematocrit measurement methods of the prior art. Furthermore because there is no need for a redox substance to measure the hematocrit level the hematocrit level can be measured at low cost.
