摘要： A method is provided for differentiation of nucleated red blood cells. In addition, the method provides for a concurrent differentiation of leukocytes in a blood cell sample by suitable electronic and optical measurements. The method includes exposing a blood cell sample to a reagent system to lyse mature red blood cells and subsequently analyzing nucleated red blood cells in a flow cell by optical analysis. A concurrent differentiation of nucleated blood cells and leukocytes can be performed using electronic and optical analysis. The electronic and optical analysis includes light scatter and impedance measurements. This method eliminates the use of nuclear stain for identification of nucleated red blood cells. The method of the present invention, for the first time, reports differentiation and enumeration of nucleated red blood cells without using fluorescence.

摘要： Methods of prevention and correction of white blood cell interferences to the measurements of mean cell volume (MCV), red blood cell concentration (RBC) and hematocrit (Hct) of a blood sample are disclosed. The interference to MCV can be prevented by identifying a valley between the red blood cell and white blood cell modes on the red blood cell distribution histogram, defining a red blood cell region using the valley and calculating MCV within the defined region. Alternatively, a curve fit of the white blood cell population on the red blood cell distribution histogram can be used to exclude the white blood cells. RBC can be corrected by subtracting the white blood cell concentration obtained from the analysis of a second aliquot sample, when the white blood cell concentration (WBC) exceeds a predetermined criterion. Hct of the blood sample can be calculated using the obtained MCV and RBC.

摘要： A method for differentiating and enumerating nucleated red blood cells in a blood sample is described. The method includes the steps of lysing red blood cells of a blood sample with a lytic reagent, measuring nucleated blood cells by DC impedance measurement in a non-focused flow aperture, differentiating nucleated red blood cells from other cell types, and reporting nucleated red blood cells in the blood sample.

摘要： This invention relates to lytic reagents and methods of using the lytic reagents for automatically determining leukocyte subpopulations in blood. More specifically, the new lytic reagents selectively lyse red blood cells and certain leukocyte subpopulations, which enables the differentiation of at least one subpopulation of leukocytes. The lytic reagents contain a polyoxyethylene based surfactant, a quatemary ammonium salt and an acid. When used in combination with a second lytic reagent system, one is able to obtain at least a five part differential of leukocytes by impedance and light scatter measurements, by impedance and radio frequency measurements, or by radio frequency and light scatter measurements.

摘要： A lytic reagent composition for measuring nucleated blood cells in a blood sample is described. The lytic reagent composition contains a quaternary ammonium surfactant, an ethoxylated phenol, and an ethoxylated alcohol. When mixed with a blood sample, the lytic reagent composition lyses red blood cells and enables a differentiation of nucleated red blood cells from other cell types by DC impedance measurement. The lytic reagent composition can further contain an organic ligand for determining total hemoglobin concentration of a blood sample photometrically. Further disclosed is a lytic reagent system including the lytic reagent composition and a diluent. In addition, a single reagent composition containing salts is also disclosed, which can be used without a separate diluent. The lytic reagent compositions can be used for concurrent measurement of nucleated red blood cells, WBC, and hemoglobin of a blood sample.
