A method to provide control samples for validating a diagnostic test within a laboratory system is presented. The laboratory system comprises an aliquoting device, a storage, a transport system, at least two analyzers, and a control unit. A total number of control sample aliquots and an aliquot volume for each control sample aliquot is determined based on a validation time schedule. A provided total control sample volume is aliquoted into the determined total number of control sample aliquots with the determined aliquot volumes. The generated control sample aliquots are transported to one or more of the at least two analyzers according to the validation time schedule.

A laboratory system for a laboratory automation system is presented. The laboratory system comprises a sample container carrier. The sample container carrier is configured to carry a laboratory sample container and comprises a removal detector. The removal detector is configured to interact with the laboratory sample container to detect a removal of the carried laboratory sample container from the sample container carrier. Furthermore, the laboratory system is configured to determine based on the detected removal that a before valid logic assignment of the sample container carrier to the carried laboratory sample container is invalid.

The invention relates to a method for detecting a particle in a container filled with liquid, the method having the following steps: dispensing a liquid sample into the container, scanning a partial volume area of the container in order to detect a particle located in the liquid sample, characterized in that an upper limit and a lower limit of the partial volume area is determined in a calibration operation upstream of the dispensing process.

A tissue processing device includes a cassette for carrying tissue; a cassette container in which the cassette is received; a working stage, the cassette container being movably disposed on an upper side of the working stage; and an elastic vessel disposed on a lower side of the working stage, wherein the working stage defines a through hole, the cassette container communicates with the elastic vessel by means of the through hole, and each elastic vessel is configured to squeeze a reagent contained therein into the cassette container when the elastic vessel is deformed and to suck the reagent from the cassette container into the elastic vessel when the elastic vessel is restored. When the elastic vessel is deformed, the reagent therein is squeezed into the cassette container so that the tissue is immersed by the reagent, and when the elastic vessel is restored, the reagent contained in the cassette container is sucked into the elastic vessel to release the tissue from the reagent, so as to process the single tissue by means of a unique solution to prevent cross-contamination.

Disclosed is an automated liquid-phase immunoassay apparatus used with a cuvette having a plurality of chambers containing a reagent necessary for detection of an analyte in a biological specimen. The apparatus includes a movable cuvette module equipped with the cuvette, an optical reading module for optical assaying of a material resulting from a reaction between the specimen and the reagent, and a dispenser module which is positioned on the cuvette module and which dispenses the specimen and the reagent to the plurality of chambers of the cuvette and washes the specimen and the reagent therefrom.

[Problem] To ensure that a fluid is prevented from overflowing from a well and exposing the user to a biohazard. [Solution] A cartridge for use in measuring a component to be measured contained in a fluid includes a recessed well, formed for storing the fluid, the well including: a lower barrel portion that defines a lower space having a closed bottom; and an upper barrel portion that is formed above the lower barrel portion and defines an upper space having an opening on the top end, wherein a step portion is formed between the lower barrel portion and the upper barrel portion, the step portion being formed on an inner wall surface of the well and defining a step that continuously connects the inner wall surface of the lower barrel portion and the inner wall surface of the upper barrel portion.

Disclosed is a fully-automatic chemiluminescence immunoassay analyzer, which comprises a base, a reaction cup conveyance module, a robot-arm sample injection module, an incubation module, a manipulator and transit module, a magnetic-separation cleaning module, and a detection module are mutually independently integrated on the base. The reaction cup conveyance module is used for conveying a reaction cup to a pre-determined position; the manipulator and transit module carries the reaction cup into the incubation module, to incubate the reaction cup for a constant-temperature reaction; the reaction cup in the incubation module is carried to the magnetic-separation cleaning module for magnetic-adsorption cleaning; and the reaction cup after cleaning is carried by the manipulator and transit module to the detection module for detection. A plurality of manipulators and a plurality of transit devices may be disposed as required, to link the mutually independent functional parts of the modules. Further, the instrument may be equipped with detection modules and process modules of various detection platforms, which cooperate with the manipulator and transit module to realize diverse detection in a table-top production line manner.

In an automatic analyzer in which required maintenance can be executed efficiently, without omission, an operation control unit controls operations of an analysis module (ISE, AU1, AU2) including a sample vessel transport mechanism, a reagent vessel transport mechanism, a reaction vessel transport mechanism, a sample dispensing mechanism, and a reagent dispensing mechanism, and of a display unit, and analyzes a sample accommodated in a reaction vessel. The operation control unit stores a validity period for each maintenance item of the analysis module (ISE, AU1, AU2) and an execution time for each maintenance item in a memory, displays an execution time together with an identification representation of execution priority level based on the expiration dates on the display unit, rearranges the display order of the maintenance items on the basis of the execution priority level, in accordance with an operator's instruction inputted through an operation input portion.

The invention provides devices that improve tests for detecting specific cellular, viral, and molecular targets in clinical, industrial, or environmental samples. The invention permits efficient detection of individual microscopic targets at low magnification for highly sensitive testing. The invention does not require washing steps and thus allows sensitive and specific detection while simplifying manual operation and lowering costs and complexity in automated operation. In short, the invention provides devices that can deliver rapid, accurate, and quantitative, easy-to-use, and cost-effective tests.

Systems for monitoring metabolites may include a sample collection system and a urinalysis system of or for a toilet. The sample collection system may be automated to collect sample urine from a toilet or toilet area, transport the sample to the urinalysis system, and/or the sample urine for analysis at a later time or after analysis by the urinalysis system. The urinalysis system may be automated by proactively providing test material on which a subject may provide a urine sample. Once the urine sample has been provided the urinalysis system may provide the test material to an analyzer for analysis. Results of the analysis of the test material and sample urine may be provided to a mobile device of the subject and/or a remote server. The urinalysis system may provide a urine sample to a mass spectrometry unit for analysis.
