  • Patent number: 7208319
    Abstract: Methods are provided for measurement of nucleated red blood cells in a blood sample. The methods include exposing a blood cell sample to a reagent system to lyse mature red blood cells, subsequently analyzing nucleated red blood cells in a flow cell by axial light loss, DC impedance, and medium angle light scatter measurements; by axial light loss, low angle light scatter, and medium angle light scatter measurements; or by axial light loss, DC impedance, low angle light scatter, and medium angle light scatter measurements; and then differentiating nucleated red blood cells from other cell types by using measured signals and/or functions thereof.

  • Publication number: 20070054404
    Abstract: A method of measuring a hemoglobin parameter of a test sample of blood comprises diluting and lysing a test sample. Then, a temperature corresponding to the test sample is obtained. The diluted and lysed test sample is then delivered to a cuvette, and a spectrophotometer determines the absorbance and/or transmittance of the sample in the cuvette. With the absorbance and/or transmittance of the test sample, a first measurement of the hemoglobin parameter of the test sample is obtained. After a first measurement of the hemoglobin parameter is obtained, a processor determines a corrected measurement of the hemoglobin parameter of the test sample. The corrected measurement is a function of the measured temperature that corresponds to the test sample and the first measurement of the hemoglobin parameter. The method of measuring a hemoglobin parameter is valid over a range of test sample temperatures.

  • Patent number: 6472215
    Abstract: A method of analyzing nucleated red blood cells (NRBCs) in a blood sample and further enumerating NRBCs is disclosed. The method includes lysing a first aliquot and a second aliquot of a blood sample separately with a first lysing reagent system and a second lysing reagent system; measuring the first sample mixture in a flow cell by DC, RF, and light scatter measurements; measuring cell distributions and counting remaining blood cells in the second sample mixture by DC impedance measurements in a non-focused flow aperture; analyzing blood cell distribution patterns obtained from measuring the first sample mixture and from measuring the second sample mixture respectively; and further performing a combined analysis to differentiate NRBCs from other cell types and determine numbers of NRBCs in the blood sample.
