The present invention relates to a method for analyzing urine sample, a reagent for the analysis of a urine sample and a reagent kit for the analysis of a urine sample, which are used for detecting at least casts and erythrocytes as urinary particles.

Method for urine sample analysis, reagent for urine sample analysis, and reagent kit for urine sample analysis

This blood analyzer includes a sample preparation portion preparing a measurement sample free from a labeling substance from a blood sample and a hemolytic agent free from a labeling substance, a light information generation portion generating fluorescent information and at least two types of scattered light information from the measurement sample and a control portion performing a first classification of white blood cells in the measurement sample into at least four groups of monocytes, neutrophils, eosinophils and others on the basis of the fluorescent information and the two types of scattered light information.

Blood analyzer, blood analysis method and hemolytic agent

This blood analyzer includes a sample preparation portion preparing a first measurement sample containing a blood sample and a hemolytic agent and a second measurement sample containing the blood sample, the same hemolytic agent as the hemolytic agent and a staining agent and a control portion classifying white blood cells in the first measurement sample into at least four groups of monocytes, neutrophils, eosinophils and others on the basis of fluorescent information and two types of scattered light information generated by a light information generation portion and classifying blood cells in the second measurement sample into at least malaria-infected red blood cells and others on the basis of fluorescent information and scattered light information generated by the light information generation portion.

Blood analyzer, blood analysis method, hemolytic agent and staining agent

The present invention provides a reagent kit for analyzing a sample comprising a first reagent containing a cationic surfactant, a nonionic surfactant and an aromatic carboxylic acid and a second reagent containing a fluorescent dye capable of staining nucleic acid, and a method for analyzing a sample using the kit.

Reagent kit for sample analysis and sample analysis method

A reagent container set is disclosed which comprises: a first reagent container for accommodating a first reagent to be used in a sample analyzer, the top part of the first reagent container having a first aspiration opening for inserting a first reagent aspirating tube to aspirate the first reagent; a waste fluid container for accommodating the first reagent used in the sample analyzer as a waste fluid, the top of the waste fluid container having a discharge opening for inserting a waste fluid discharging tube to discharge the waste fluid into the waste fluid container; a box for accommodating the first reagent container and the waste fluid container; and a container holding member for holding the first reagent container and the waste fluid container so that the first aspiration opening and the discharge opening are disposed at predetermined positions, the container holding member being maintained at a predetermined position within the box.

Reagent container and reagent set

A reagent for partially lysing a cell membrane of a red blood cell infected with a malaria parasite, comprising: a first surfactant which has predetermined lysing ability for the red blood cell membrane; and a second surfactant which has weaker lysing ability than that of the first surfactant; wherein the reagent has pH of 5 to 7 and osmotic pressure of 200 to 300 mOsm/kg&#xb7;HO; and wherein the reagent partially lyses the malaria infected red blood cell membrane such that a malaria parasite is retained in the red blood cell and fluorescent dye passes through the cell membrane, is disclosed. A reagent for detecting malaria infected red blood cells, and a sample analyzing method for detecting malaria infected red blood cells, are also disclosed.

Reagent for partially lysing a cell membrane of a red blood cell, a reagent for detecting malaria infected red blood cells, and a sample analyzing method for detecting malaria infected red blood cells

A method for detecting abnormality in the morphology of erythrocytes, which comprises:
