The method for generating an index for managing the analytical accuracy of a sample analyzer includes a step of acquiring a determination result related to whether a sample is positive or negative from a plurality of sample analyzers, and a step of generating an index based on a ratio of a sample determined to be positive or negative by the plurality of sample analyzers from a plurality of determination results obtained from the plurality of sample analyzers.

Provided is a sample processing apparatus management system, sample processing apparatuses and a management apparatus, and a management method that can accurately and easily adjust the respective sample processing apparatuses irrespective of their individual differences. When abnormality has occurred in a sample analyzer, the sample analyzer requests approval for self-adjustment from a management server. The management server determines whether to permit performance of the self-adjustment, and when having determined to permit the self-adjustment, notifies the sample analyzer of the approval for the self-adjustment. When the approval for the self-adjustment has been notified of, the sample analyzer performs the self-adjustment.

Provided is an automatic analysis device that estimates causes of change in measurement values of a quality-control substance. An automatic analysis device that analyzes specimens includes an acquisition unit that acquires amount of change in measurement values of a quality-control substance used for quality control, a calculation unit that calculates a change prediction amount on the basis of a difference value in concentration values of a standard solution used for calibration before and after changing lots, and an estimation unit that estimates causes of change occurring in measurement values of the quality-control substance on the basis of results of comparing the amount of change and the change prediction amount.

A method of controlling a blood analyzer for measuring platelets is provided. The method comprises: determining a relationship between at least one first measurement value obtained by detecting platelets in at least one previous test by an electrical type detector of the blood analyzer and at least one second measurement value obtained by detecting the platelets in the at least one previous test by an optical type detector of the blood analyzer, and controlling the blood analyzer to prepare the first and/or second measurement sample for a current test according to the determined relationship.

An automatic analysis device has a plurality of types of photometers having different quantitative ranges, and an analysis control unit for quantifying the desired component in specimens based on measurement values of one or more photometers selected from among the plurality of types of photometers. The analysis control unit: sets a switching region in an overlap region of respective quantitative ranges of the plurality of types of photometers, said switching region having a greater width than does the variation in quantitative values of the desired component based on the measurement values of photometers having the same specimen; compares the quantitative value of a quantitative range portion that corresponds to the switching region and the quantitative values of the desired component based on the measurement values of the photometers; and selects a photometer to be used in quantitative output of the desired component from among the plurality of types of photometers.

Provided is an analysis device capable of reducing vibration and noise generated by a stepping motor due to countermeasure for step-out of the stepping motor. A drive unit is controlled such that a set value of driving torque of the stepping motor increases stepwise in a plurality of steps each time the step-out of the stepping motor is detected by the step-out detection unit.

An automated method for performing a leakage test of a fluidic system of an in-vitro diagnostic device as well as an automated in-vitro diagnostic device comprising a controller configured to perform the leakage test. The method comprises activating a pump to provide a fluid from a fluid supply into an electrically conductive probe. The probe is positioned so that a tip of the probe is at a predetermined distance from a reference surface of a reference element. In case of leakage, an electrical signal or change in an electrical signal or a change of the electric or magnetic field between the probe and the reference element is detected in a predetermined measuring time period and at least one maintenance action is triggered.

An information provision device includes an acquisition unit and an information output unit. The acquisition unit acquires test result data indicating a Cq value of a well obtained by a test device performing a polymerase chain reaction (PCR) test on a standard device having the well in which a known number of copies of a nucleic acid are disposed. The information output unit outputs comparison information obtained by comparing information obtained from evaluation target data that is the evaluation target data of an evaluation target with information obtained from one or more pieces of the test result data different from the evaluation target data.

A quality control sample measurement method, a sample analysis device and a supply device capable of normally acquiring a measurement result of a quality control sample are provided. The quality control sample measurement method for measuring a quality control sample stored in a cold state includes a step of stirring the quality control sample in a first operation mode (step S2) and a step of measuring the stirred quality control samples (step S3). The stirring in the first operation mode differs from the stirring in the second operation mode for stirring the subject sample collected from the subject.

A sample testing system includes a test receptacle support structure, an optical element positioned for transmitting electromagnetic radiation emitted or reflected by a sample disposed in a test receptacle supported by the test receptacle support structure, a cleaning member, and an automated transport arm configured to (i) detachably couple the cleaning member, (ii) move the detachably-coupled cleaning member into a position proximate to and/or contacting the optical element, and (iii) decouple the cleaning member.
