    摘要: Systems and methods for analyzing blood samples, and more specifically for performing a white blood cell (WBC) differential analysis. The systems and methods screen WBCs by means of fluorescence staining and a fluorescence triggering strategy. As such, interference from unlysed red blood cells (RBCs) and fragments of lysed RBCs is substantially eliminated. The systems and methods also enable development of relatively milder WBC reagent(s), suitable for assays of samples containing fragile WBCs. In one embodiment, the systems and methods include: (a) staining a blood sample with an exclusive cell membrane permeable fluorescent dye, which corresponds in emission spectrum to an excitation source of a hematology instrument; (b) using a fluorescence trigger to screen the blood sample for WBCs; and (c) using measurements of (1) axial light loss, (2) intermediate angle scatter, (3) 90° polarized side scatter, (4) 90° depolarized side scatter, and (5) fluorescence emission to perform a differentiation analysis.

    摘要: Provided herein are systems and methods for analyzing blood samples, and more specifically for performing a basophil analysis. In one embodiment, the systems and methods include: (a) staining a blood sample with an exclusive cell membrane permeable fluorescent dye; and then (b) using measurements of light scatter and fluorescence emission to distinguish basophils from other WBC sub-populations. In one embodiment, the systems and methods include performing a basophil cluster analysis of the blood sample, based on the combination of light scatter and fluorescence measurements.

    摘要: A method for increasing the throughput, or the precision, or both the precision and the throughput, of a flow cytometer, or of a hematology analyzer employing a flow cytometer, and for further reducing the complexity of such a cytometer or analyzer, by utilizing the technique of laser rastering in combination with a lysis-free single-dilution method. Laser rastering involves sweeping a laser beam across a flowing sample stream in a hematology analyzer. A lysis-free single-dilution method involves performing all the flow cytometer measurements on a sample using a single aliquot, a single lysis-free reagent solution, a single dilution, and a single pass of said dilution through the measurement apparatus. An apparatus suitable for carrying out the method of this invention comprises an optical module comprising a source of light, a scanning device, a lens or system of lenses, a flowcell, detectors, and filters; and an electronic module comprising preamplifiers, analog signal conditioning elements, analog-to-digital converters, field-programmable gate arrays, digital signal processing elements, and data storage elements.

    摘要: Systems and methods for analyzing blood samples, and more specifically for performing a nucleated red blood cell (nRBC) analysis. The systems and methods screen a blood sample by means of fluorescence staining and a fluorescence triggering strategy, to identify nuclei-containing particles within the blood sample. As such, interference from unlysed red blood cells (RBCs) and fragments of lysed RBCs is substantially eliminated. The systems and methods also enable development of relatively milder reagent(s), suitable for assays of samples containing fragile white blood cells (WBCs). In one embodiment, the systems and methods include: (a) staining a blood sample with an exclusive cell membrane permeable fluorescent dye; (b) using a fluorescence trigger to screen the blood sample for nuclei-containing particles; and (c) using measurements of light scatter and fluorescence emission to distinguish nRBCs from WBCs.
