The automatic analyzer includes: a sample dispensing unit that dispenses a sample into a reaction vessel; a reagent dispensing unit that dispenses a reagent into the reaction vessel; a control unit that controls the sample dispensing unit and the reagent dispensing unit; and a measurement unit that measures a mixed solution of the sample and the reagent mixed in the reaction vessel. The reagent includes three types of reagents of: a first reagent that specifically binds to an antigen in the sample; a second reagent that specifically binds to a site different from that to which the first reagent binds with respect to the antigen and has a label to be detected by the measurement unit; and a third reagent that specifically binds to a site different from the binding site of the first reagent and the antigen and contains insoluble carriers.

The invention lies in the field of laboratory automation and relates to a laboratory analysis system 100, in which a plurality of analysis devices 1 and an image recording station 101 are connected to a transportation apparatus 102 for sample vessels and in which sample-vessel-specific information items, which are established in the image recording station 101, are used for controlling the pipetting apparatuses in the analysis devices 1.

A method of characterizing a specimen for HILN (H, I, and/or L, or N). The method includes capturing images of the specimen at multiple different viewpoints, processing the images to provide segmentation information for each viewpoint, generating a semantic map from the segmentation information, selecting a synthetic viewpoint, identifying front view semantic data and back view semantic data for the synthetic viewpoint, and determining HILN of the serum or plasma portion based on the front view semantic data with an HILN classifier, while taking into account back view semantic data. Testing apparatus and quality check modules adapted to carry out the method are described, as are other aspects.

Embodiments disclosed herein relate to methods and systems for performing automated assays, and particularly to performing sequential assays on a sample on an automated instrument.

An automatic analyzer includes sample vessels containing samples to be measured and; reaction vessels in which to mix a sample and a reagent. A sample dispenser 5 dispenses a sample from any of the sample vessels to any of the reaction vessels. A reagent dispenser dispenses a reagent from a reagent vessel to a reaction vessel, and a stirrer stirs the sample-reagent mix contained in the reaction vessel. A photometric measurement unit is provided for obtaining multiple measurement data points during the progress of reaction of a mixed solution. At least one approximation formula is performed and an approximation curve from the measurement data points is generated. A shape descriptor is calculated from the approximation curve and abnormalities based on the shape descriptor are determined. This not only allows abnormalities to be detected accurately from each measurement result, but also allows the causes of the abnormalities to be identified.

A biochemical analyzer has a control section which outputs the results of analysis of measurement values from a reactant measured by a multi-wavelength photometer to a host device through a communication section. The control section causes both analyte identification information for identifying the analyte instructed to be retested through the communication section from the host device and analyte receptacle positional information indicative of the position of a sample receptacle receiving the analyte instructed to be retested from the host device on a sample turntable to be displayed on a display unit.

An analysis device according to the present invention comprises: at least one inspection device that inspects a specimen; and at least one specimen production device that produces a specimen. The analysis device is provided with a data processing unit that processes data. The inspection device and the specimen production device are each provided with a communication unit for communicating with each other. The specimen production device is provided with a control unit that controls the specimen production device and a production unit that produces a specimen. The inspection device is provided with a control unit that controls the inspection device and an inspection unit that inspects a specimen. The data processing unit calculates a value [number of specimens A] representing the number of specimens which have not been delivered to the inspection device and a value [number of specimens B] representing the sum of the number of specimens for which inspection can be additionally started in the inspection device and the number of specimens which are being inspected and the inspection of which will be completed in a prescribed time. The control unit of the specimen production device prohibits production of a new specimen in the specimen production device when the [number of specimens A] and the [number of specimens B] satisfy a first relationship.

To provide a technique that suppresses the degradation of analysis accuracy and the contamination of an analyzer caused by an abnormality in a stirring device. An automatic analyzer of the present disclosure includes a stirring device having a rod-shaped member that stirs a stirred solution and a power source that applies power to the rod-shaped member, a sensor that detects vibrations of the stirring device, and a processor that determines a state of the stirring device based on a detection signal of the vibrations from the sensor. The processor calculates a feature value of the vibrations based on the detection signal of the vibrations, and the processor determines that the rod-shaped member bends when the feature value of the vibrations is a first predetermined value or more.

Systems and apparatus with circuits that are configured to detect fallen containers upstream or proximate an intake zone suitable for automated evaluation apparatus using different sensors, including at least one lower sensor and at least one upper sensor which is positioned to project an optical signal at a height corresponding to a top portion of an upright container to thereby allow an increased reliability in detection of different orientations and positions of fallen containers. An optional second lower sensor may be used which is longitudinally spaced apart from the first lower sensor and the lower sensors can transmit optical signals across the container travel path that do not intersect.
