Abstract: A method for operating and diagnosing faults in a laboratory instrument comprising a plurality of subsystems may comprise performing an analytic sequence and a set of diagnostic steps. Such a method may be performed using a diagnostic reagent comprising paramagnetic particles and lacking an antibody component. Such a method may also include evaluating a set of the instrument's subsystems in the opposite of the order in which those subsystems are used during analysis.

Abstract: A substance dispense system is provided for a biological sample analysis instrument. The substance dispense system can operate to prepare a fluidic substance, such as a sample, using a dispense tip in different operational modes based on the volume of the fluid substance to be prepared. The substance dispense system thereby improves accuracy and/or precision in pipetting with the dispense tip.

Abstract: An automatic analyzer capable of avoiding carry-over between samples, and a sample dispensing method, are provided. To that end, an automatic analyzer (1) for performing analysis of both assay menu with a high carry-over avoiding level and assay menu with a low carry-over avoiding level, includes: a first sample dispensing apparatus (6) loaded with a disposable tip (60a) for sample dispensing for assay menu with a high carry-over avoiding level, and for subdividing and dispensing a sample for assay menu with a low carry-over avoiding level; an aliquot container (9) for subdividing and containing a sample for assay menu with a low carry-over avoiding level, subdivided and dispensed by the first sample dispensing apparatus (6); and a second sample dispensing apparatus (5) loaded with a reusable probe (50), for sample dispensing for assay menu with a low carry-over avoiding level.

Abstract: Provided is an abnormality-identifying method for identifying an abnormality in an analyzer which analyzes a specimen based on optical measurement. The method includes firstly acquiring a reference value which is a measurement result obtained by using a low-concentration reagent containing a component in predetermined very low concentrations, secondly acquiring an abnormality-identification measurement value which is a measurement result obtained through an analysis process using a high-concentration reagent containing the component in predetermined high concentrations, and identifying an abnormality in an analysis process concerning removal of the high-concentration reagent based on whether the abnormality-identification measurement value is within an acceptable range set based on the reference value.

Abstract: An error specifying method of specifying an error of an analyzer. The method specifies an error related to removal of a high-concentration reagent. The method includes a low-concentration reagent measuring step of performing an analysis process, which causes a composition to emit light, on a low-concentration reagent and measuring an amount of light emitted in order to acquire performance of the low-concentration reagent; a high-concentration reagent measuring step of performing the analysis process on the high-concentration reagent and measuring an amount of light emitted in order to acquire performance of the high-concentration reagent; and a reagent evaluating step of evaluating the performance of the low-concentration reagent and the performance of the high-concentration reagent based on the measurement results in the low-concentration reagent measuring step and the high-concentration reagent measuring step.

Abstract: Provided is an abnormality-identifying method for identifying an abnormality of an analyzer which analyzes a specimen based on optical characteristics. All predetermined analysis processes to be performed on the specimen but an analysis process whose abnormality is to be examined are eliminated, and the abnormality of the analyzer is identified based on a measurement result which is obtained through the analysis process whose abnormality is to be examined and a reaction process in which a substance whose abnormality is to be identified or a predetermined reagent is reacted with a predetermined reactant.

Abstract: An abnormality identifying method is for identifying an abnormality detail in an analyzing apparatus that analyzes a specimen based on optical measurement. The method includes: for a reagent having a same function as an intermediate product produced during analysis processes, canceling a predetermined analysis process other than an analysis process to be verified for abnormality from among analysis processes with respect to the specimen; and identifying an abnormality in the analyzing apparatus based on a measurement result obtained by performing a same analysis process as an analysis process performed on the intermediate product as well as the analysis process to be verified for abnormality.
