According to one embodiment, a sample inspection apparatus includes a photodetection circuitry, an image sensor, processing circuitry, and an output interface. The photodetection circuitry has light incident on an optical waveguide in an inspection container and detects the light having propagated within the optical waveguide and coming out of the optical waveguide. The image sensor acquires an image signal for the optical waveguide, using scattered light originated from the light propagating within the optical waveguide. The processing circuitry acquires one or more inspection index values based on at least one of an output of the photodetection circuitry or an output of the image sensor. The output interface outputs a result of processing by the processing circuitry.

Sample inspection apparatus

According to one embodiment, a specimen measurement apparatus includes a detector, a reaction promoter and processing circuitry. The detector generates an electrical signal based on a reactive state in a reaction chamber in which a mixture of a test substance and a reagent is contained. The reaction promoter supplies to the reaction chamber energy to promote reaction in the reaction chamber. The processing circuitry switches an energy supply state in accordance with a predetermined time schedule, determines a stationary state of the test substance based on an electrical signal generated after the energy supply state is switched, and outputs the stationary state obtained by the determination.

A measuring apparatus uses a biological component sensor including a plate-shaped sensor chip having a biological component sensing function and a sensor chip holding frame surrounding and holding the sensor chip. The biological component sensor is disposed in a measuring apparatus main body housing. A fixed engaging member and movable engaging member disposed on a sensor chip support table fixed to the measuring apparatus main body housing fix and support the sensor chip holding frame, and the sensor chip can be thus replaced. The biological component sensor contacts a forearm portion of a human body, and a biological component exuded from a contact part of the forearm portion is caused to contact the sensor chip to change a physical or chemical surface property of the sensor chip, thereby measuring the change through an irradiation of an inspection light to calculate concentration of the biological component.
