Abstract: A sample analyzer capable of preventing the loss of lids of liquid containers used in the sample analyzer is provided. The sample analyzer 1 has liquid suctioning units 11 and 17 which are provided with suction tubes for suctioning liquid, container setting units 13 through 15 for setting a plurality of liquid containers 5 through 8 holding liquid, and lid placing sections 16a through 16c and 32 through 34 for placing lids 5a through 8a of liquid containers 5 through 8.

Abstract: A standard material that is used for judging an abnormal portion in a particle analyzer is described. The standard material comprises first standard particles to be fluorescence-stained by a fluorescence-staining treatment and second standard particles that have preliminarily contained a fluorescence dye. A method and an analyzer that can judge an abnormal portion in a particle analyzer by using such a standard material are also described.

Abstract: Analyzers and methods of analysis are described for performing blood cell counting and immunoassay on a whole blood specimen in one measurement section. An assay sample is prepared by blending carrier particles sensitized with an antibody or an antigen against a substance to be immunoassayed and a fluorescent dye for staining blood cells with the whole blood specimen. Optical information is detected from a particle in the assay sample, and the blood cells are differentiated and counted based on the detected optical information. A rate of agglutination of the carrier particles is obtained based on the detected optical information, thereby enabling detection of the substance to be immunoassayed.

Abstract: An immunoassay apparatus is described that includes a measuring sample preparing section for preparing a measuring sample by mixing a specimen with carrier particles on which an antibody or an antigen against an analyte is immobilized, a detector for detecting internal information and size information from particles contained in the measuring sample and a controller for identifying the carrier particles on the basis of the obtained internal information and for calculating a degree of aggregation of the identified carrier particles on the basis of the obtained size information. An immunoassay method is also described.

Abstract: Immunoassay methods, apparatuses, and reagents are described, which are capable of measuring with out being affected by particles other than a measuring object substance in a specimen, and which do not require a labeled antibody even when such particles are included in the specimen. In addition, immunoassay methods, apparatuses, and reagents capable of simultaneously measuring multiple parameters from one sample are described.
