  • Publication number: 20200141858
    Abstract: 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.

  • Publication number: 20200141859
    Abstract: 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.
