The present invention provides a method for accurately measuring a blood component despite uneven distribution of blood introduced into a capillary. The measurement method according to the present invention is characterized in that a plurality of electrode systems for measuring the hematocrit are provided in a capillary of a biosensor to measure the hematocrit at different positions in the capillary. By measuring the hematocrit at the plurality of positions in the capillary as described above, the hematocrit can be measured mom accurately despite uneven distribution of blood introduced into the capillary.

Method for measuring amount of blood component in blood

The present invention provides a method for accurately measuring a blood component despite uneven distribution of blood introduced into a capillary. The measurement method according to the present invention is characterized in that a plurality of electrode systems for measuring the hematocrit are provided in a capillary of a biosensor to measure the hematocrit at different positions in the capillary. By measuring the hematocrit at the plurality of positions in the capillary as described above, the hematocrit can be measured more accurately despite uneven distribution of blood introduced into the capillary.

A biosensor detects a target substance contained in a liquid sample and includes an insulating base plate having a recess formed in a portion that is thinner than the surrounding part, a working electrode and a counter electrode, at least one of which is disposed in the recess. A reaction reagent is disposed in the recess and reacts with a specific substance in the liquid sample.

Biosensor, method of producing the same and detection system comprising the same

The measurement device comprises a sensor holder to which is removable to a biosensor. The sensor holder has measurement-use connection terminals that are in contact with the electrode system in the biosensor and are used to take off signals required for measuring the specific component, and thermocouple-use connection terminals that are in contact with the thermocouple in the biosensor and are used to take off the thermoelectromotive force signals.

Method for measuring analysis object and measuring device

A biosensor includes a cavity for holding a sample, an electrode system for measuring the sample concentration in the cavity, and a thermocouple for obtaining temperature information during measurement. A measurement device includes a reference temperature junction sensor or an environmental temperature sensor for measuring the temperature of reference temperature junctions of the thermocouple. A temperature compensation measures the temperature difference between a measuring junction and a reference temperature junctions of the thermocouple, and specifies the temperature of a reference temperature junction, thereby using the temperature information as the temperature of a measurement component and performing accurate temperature compensation from the measuring junction temperature information and the environmental temperature information with respect to the measured values.
