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.
