    • Voltage is applied across a counter electrode and a working electrode, with which a blood sample is in contact, in such a state that an oxidant in a redox substance is not substantially in contact with a working electrode but is in contact with a counter electrode and a reductant is not substantially in contact with the counter electrode but is in contact with the working electrode, whereby the reductant and the oxidant are respectively oxidized and reduced to measure current produced upon the oxidation and reduction. According to the above constitution, while lowering the voltage applied across the working electrode and the counter electrode, the Hct value of the blood sample can be measured stably with a satisfactory detection sensitivity. This measurement can be carried out with a sensor chip comprising a working electrode (11), a counter electrode (12), and a blood sample holding part (14) having branch parts (18a, 18b). A first reagent (13) consisting essentially of an oxidant in a redox substance is disposed in contact with the surface of a counter electrode which faces the branch part (18b), and a second reagent (19) consisting essentially of a reductant is disposed in contact with the surface of a working electrode that faces the branch part (18a).
    • 在氧化还原物质中的氧化剂基本上不与工作电极接触但与对电极接触的状态下,跨越对置电极和与血液样品接触的工作电极施加电压, 还原剂基本上不与对电极接触,而是与工作电极接触,由此还原剂和氧化剂分别被氧化和还原,以测量在氧化和还原时产生的电流。 根据上述结构,在降低施加在工作电极和对电极两端的电压的同时,能够以良好的检测灵敏度稳定地测定血液样品的Hct值。 该测量可以用包括工作电极(11),对电极(12)和具有分支部分(18a,18b)的血液样本保持部分(14)的传感器芯片进行。 基本上由氧化还原物质中的氧化剂组成的第一试剂(13)被设置成与面对分支部分(18b)的对电极的表面接触,并且基本上由还原剂组成的第二试剂(19)设置在 与面向分支部(18a)的工作电极的表面接触。
