Abstract: To provide an inspection cartridge capable of preventing a user from using a blood sample of a wrong vacuum blood collection tube when the user dispenses the blood sample from the vacuum blood collection tube to the inspection cartridge, and a blood inspection device which performs a blood inspection using the same. An inspection cartridge used for performing a blood inspection with a blood inspection device provided with an identifier for identifying an anticoagulant usable in the inspection cartridge.

Abstract: A measurement chip including a prism, a metal film, and a capturing body is prepared. In a state in which a specimen is present on the metal film, scattered light obtained when first light which passes through the metal film and the specimen is scattered in the specimen when the first light is applied to the metal film from a prism side at a first incident angle smaller than a critical angle is detected. In a state in which a substance to be measured is captured by the capturing body and the specimen is not present on the metal film, a signal indicating an amount of the substance to be measured generated in the measurement chip when second light is applied to the metal film at a second incident angle not smaller than the critical angle from the prism side is detected. On the basis of a hematocrit value of the specimen determined from a light amount of the scattered light, a measurement value indicating the amount of the substance to be measured determined from the signal is corrected.

Abstract: A method for detecting an analyte according to the present invention includes: a first step of supplying a specimen to a detection device having a first ligand that is immobilized on a substrate and is capable of specifically binding to the analyte, the specimen being supplied onto the substrate of the detection device, and then causing the analyte included in the specimen to bind to the first ligand; a second step of supplying, onto the substrate, a second ligand that is labeled with a marker and is capable of specifically binding to the analyte, and then causing the second ligand to bind to the analyte bound to the first ligand; and a third step of measuring the second ligand bound to the analyte, wherein in the second step, carboxymethyl dextran is supplied onto the substrate.

Abstract: A specimen containing blood is divided into a first specimen and a second specimen. The blood in the second specimen is hemolyzed. The first specimen containing a substance to be measured is introduced into an accommodating unit and a measurement value indicating an amount of the substance to be measured in the first specimen in a state in which the blood is not hemolyzed is acquired. In a state in which the second specimen in a state in which the blood is hemolyzed is present in the accommodating unit of a measurement chip, second light acquired when first light including light of a wavelength absorbed by a red blood cell passes through the second specimen in the accommodating unit is detected. On the basis of a detection result of the second light, a hematocrit value of the specimen is determined. The measurement value is corrected on the basis of the hematocrit value.
