Abstract: A method for identifying, analyzing, and quantifying the cellular components of whole blood by means of an automated hematology analyzer and the detection of the light scattered, absorbed, and fluorescently emitted by each cell. More particularly, the aforementioned method involves identifying, analyzing, and quantifying the cellular components of whole blood by means of a light source having a wavelength ranging from about 400 nm to about 450 nm and multiple in-flow optical measurements and staining without the need for lysing red blood cells.

Abstract: A method whereby one or more fluorescent dyes are used to bind and stain nucleic acids in certain blood cells, such as, for example, white blood cells, nucleated red blood cells, and reticulocytes, and to induce fluorescent emissions upon excitation of photons from a given source of light, such as, for example, a laser, at an appropriate wavelength. More particularly, this invention provides a method whereby a fluorescent trigger is used in a data collection step for collecting events that emit strong fluorescence, in order to separate white blood cells and nucleated red blood cells from red blood cells and platelets without the need for using a lysing agent.

Abstract: 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 WB Cs; 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.

Abstract: Herein is provided a simple, reliable and accurate method for cellular analysis on hematology analyzers. In various aspects, the methods provide separation and/or differentiation between red blood cells (RBCs) and white blood cells (WBCs) by utilizing a fluorescent dye to selectively stain WBCs such that they emit stronger fluorescence signals. The method provides optimal detection limits on WBCs and RBCs, thereby allowing analysis of samples with sparse cellular concentrations. As few as one reagent may be used to prepare a single dilution for body fluid analysis, in order to simplify the body fluid analysis. Minimal damage to WBCs is attained using the lysis-free approach described in aspects of the disclosure.
