Problems solved by technology

[0005] However, conventional analyzers using calibration curves, including the device disclosed in Patent Publication No. 2003-315343, can obtain the desired output value of "analysis result", but cannot memorize which calibration curve was used for the analysis, even if To query the analysis results, the calibration curve used cannot be determined
Therefore, even if an abnormality is found in the analysis result, the avenues for investigating the cause are limited

Embodiment Construction

[0039] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0040] [Overall structure of the instrument]

[0041] An immune analyzer 1 according to an embodiment of the present invention is a device for checking items such as hepatitis B, hepatitis C, tumor markers, and thyroid hormones with samples such as blood. As shown in FIGS. 1 and 2 , the immune analyzer 1 is mainly composed of a measurement device and a control device 400 (see FIG. 4 ) as a data processing unit connected to the measurement device. The measuring device is composed of a specimen transporter (sampler) 10, an emergency specimen and nozzle transporter 20, a pipette nozzle supply device 30, a nozzle picker 40, a specimen dispensing arm 50, reagent dispensers 60a and 60b, Reaction cup supplier 70, primary reactor 80a and secondary reactor 80b, reagent dispensing arms 90a, 90b, 90c, and 90d, BF separators 100a and 100b, transport robot assembly ...

Abstract

A sample analyzer includes: a measuring device for measuring a measurement sample including a sample and a reagent; a correction curve drawing unit for creating a calibration curve based on first measurement data obtained by measuring a measurement standard sample including a standard sample and the reagent; a calibration curve specifying information addition unit for providing calibration curve specifying information for specifying the calibration curve to the calibration curve; a measurement data processing unit for acquiring an analysis result by processing second measurement data obtained by measuring the measurement sample based on the calibration curve; and an analysis result sotring unit for storing the analysis result and the calibration curve specifying information provided to the calibration curve used in the process of the second measurement data in correspondence to each other.

Description

Technical field: [0001] The invention relates to a sample analyzer for analyzing samples such as an immune analyzer and a blood coagulation analyzer Background technique: [0002] Many sample analyzers, including immune analyzers and coagulation analyzers, convert the measurement data of the samples tested in the measurement part of the analyzers with a pre-calculated calibration curve to obtain the desired analysis results. For example, in an immunoanalyzer that uses blood to test items such as hepatitis B and tumor markers, the luminescence data (photon number) of the sample obtained by measuring the luminescence quantity is obtained by measuring a standard sample (calibrator) of known concentration. The calibration curve is converted to the concentration of a certain substance. [0003] This calibration curve is usually the latest curve used for analysis, if the latest calibration curve is not suitable (the reagent used when drawing the calibration curve is different fro...
