In a clinical laboratory of a hospital, an enormous amount of effort has been required to maintain the quality of an analyzer, standard solution and control samples. An object of the present invention is to provide a control method for controlling a clinical laboratory with reduced cost, and a control apparatus using the same. In order to control data of an analyzer, standard solution, and a control sample, a support center is connected to each analyzer located in each hospital through a network line. Various kinds of analysis parameters and the result of measurements are exchanged so as to provide each clinical laboratory with a control situation in real time.

Quality control system

An automatic analyzer has a plurality of analytical units to which analysis items are allocated. When necessity of execution of calibration or accuracy management occurs, a display block relating to an occurrence cause on a state inspection screen flickers. When a receiving button corresponding to the flickering display block is instructed, the related analysis item name and analytical unit name are displayed in the display area and calibration or accuracy management is executed.

Automatic analyzer and support system therefor

In an analyzing apparatus of the present invention, sample racks, in each of which a plurality of sample containers are held, are transferred from a rack feeding unit to a discrimination unit for discriminating a type of each sample container. After the discrimination unit, a plurality of analyzing units are installed along a transfer line, and pipetters of different types are provided in the respective analyzing units. The discrimination unit detects information on the length and the width of each sample container held in each sample rack by using an optical detector. A control part selects one of the analyzing units, suitable for analyzing the sample container of which type was discriminated, based on the information detected by the discrimination unit, and transfers the sample container of which type was discriminated, to a sample pipetting position in the selected analyzing unit.

Analyzing apparatus having a function pipette samples

Dyeing agents which are excellent in visual recognition of discernible or tangible components in a sample cause no coagulation of proteins, sugars or glycoproteins dissolved in the sample. An apparatus for image analysis of flow type stain particles uses the dyeing agents, and particles of discernible components suspended in a flowing sample can be detected so that images of the particles can be efficiently photographed and the discernible components can thus be analyzed by image processing of the thus-obtained image.
