    摘要: 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 (11) and a counter electrode (12), in which a redox substance is provided on the counter electrode (12) but not on the working electrode (11); 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 (11) and the counter electrode (12); detecting the oxidation current or the reduction current; and determining a Hct value based on a value of the detected current.

    摘要: A blood test apparatus has a housing, a blood sensor, and a plurality of connectors. The blood sensor has a plurality of connection terminals that are electrically connected with each electrode of the electrode system; and a reference terminal that serves as a reference. The plurality of connectors are configured to connect to the plurality of connection terminals and the reference terminal of the blood sensor attached at a predetermined position in the blood test apparatus, respectively. And also, relations between the reference terminal and each of the plurality of connection terminals are measured to identify the reference terminal automatically.

    摘要: It is intended to provide a means of easily removing a portion of blood bleeding from pierced skin, which has not been taken into a blood sensor but remained on the skin, in a blood test with the use of a blood test apparatus. By using this means, it becomes unnecessary in the blood test to separately prepare a paper sheet, etc. for wiping off. More specifically speaking, a blood test apparatus wherein a blood sensor is provided within a blood sensor unit detachable to the blood test apparatus body and the blood sensor unit has a part to be in contact with the skin in the test and an absorption means. It is favorable that the part to be in contact with the skin in the test serves as the absorption means.
