    摘要: Methods for characterizing and distinguishing reticulocytes and mature red blood cells use reagent compositions which include organic cationic dyes for staining the reticulocytes in the blood sample and buffer solutions for maintaining a pH of about 6 to about 9. The dyes may be the blue absorption dyes Oxazine 750 or New Methylene Blue. When a zwitterionic surfactant is included in the reagent composition for isovolumetric sphering of the reticulocytes and erythrocytes, and the reagent composition and whole blood sample mixture is passed through the sensing region of a flow cytometer, the light scattered and absorbed by each cell is measured, the erythrocytes can be distinguished from reticulocytes and the volume, hemoglobin concentration and the hemoglobin content of each reticulocyte or erythrocyte, and the mean cell volume, mean corpuscular hemoglobin concentration, and mean cell hemoglobin of the reticulocytes or erythrocytes are calculated from the measured cell-by-cell volume and hemoglobin concentration. One method also includes adjusting the measured absorption signals for pseudo-absorption.

    摘要: Methods for characterizing and distinguishing reticulocytes and mature red blood cells use reagent compositions which include an organic cationic dye for staining the reticulocytes in the blood sample and a buffer solution for maintaining a pH of about 6 to about 9. The dyes may be the red excitable fluorescent dye Oxazine 750, or the blue excitable fluorescent dyes Acridine Orange or derivatives of Acridine Orange. When a zwitterionic surfactant is included in the reagent composition for isovolumetric sphering of the reticulocytes and erythrocytes, and the reagent composition and whole blood sample mixture is passed through the sensing region of a flow cytometer, the light scattered through at least one angular interval and that fluoresced by each cell is measured, the erythrocytes can be distinguished from reticulocytes and the volume, hemoglobin concentration and the hemoglobin content of each reticulocyte or erythrocyte, and the mean cell volume, mean corpuscular hemoglobin concentration, and mean cell hemoglobin of the reticulocytes and/or erythrocytes are calculated from the measured cell-by-cell volume and hemoglobin concentration.

    摘要: The enumeration and analysis of residual white blood cells in a sample of leukocyte-reduced blood products is conducted by forming a suspension of the leukocyte-reduced blood products with a sufficient amount of a lysing reagent. The lysing reagent comprises a buffer with a low molar concentration, and a non-ionic surfactant. The suspension of leukocyte-reduced blood products and the lysing reagent is incubated for a sufficient time at a temperature sufficient to selectively lyse the platelets and red blood cells without damaging the white blood cells. The white blood cells of the lysed blood products are then contacted with a suitable dye to stain the white blood cells and the number of stained white blood cells is measured. The lysing reagent is free of harsh organic solvents which can damage the plastic components of automated clinical analyzers.
