Abstract: A diagnostic device capable of measuring a concentration of glycated hemoglobin using a simple structure and a diagnostic system having the same are provided. The diagnostic device includes: a first sample supplier including a bond inhibiting substance that inhibits bonding between glycated hemoglobin and a bonding substance bound selectively to the glycated hemoglobin; a second sample supplier separated from the first sample supplier; a first chamber connected to the first sample supplier through a first passage between the first sample supplier and the first chamber; and a second chamber connected to the second sample supplier through a second passage between the second sample supplier and the second chamber.

Abstract: A fluid analysis cartridge includes: an assistant plate including an inlet hole configured to receive a fluid; a main plate configured to receive the fluid via the assistant plate and further configured to store a reagent configured to react with the fluid; and a valve provided in the inlet hole and configured to control a flow of the fluid into the main plate according to pressure in the inlet hole.

Abstract: An assay method enhances reliability of assay of a target material by removing interfering influence of non-target materials through controlling the concentration of the target material in a sample. A reagent kit, a microfluidic device, and a test apparatus are disclosed. The method includes capturing a target material using a capturing agent which selectively binds the target material and determining measured values of reaction products of an enzyme which is activated by the target material, wherein enzyme reactions are conducted in the presence and absence of the capturing agent.

Abstract: A vehicle battery diagnosis apparatus is provided that diagnoses a history of a usage state of a secondary battery of a vehicle and that presents a suppression measure against battery degradation. The vehicle battery diagnosis apparatus includes a storage unit and a diagnosis unit. The storage unit stores an alternative suppression measure for a factor responsible for degradation of the secondary battery. The diagnosis unit prohibits presentation of the alternative suppression measure as a suppression measure upon determining the alternative suppression measure fails to satisfy a prescribed presentation criterion.
