Neutrophil Gate

Neutrophils have cytoplasmic granules and multi-lobed nuclei. As such, they have a high side scatter, and are characteristically CD45+.

Differentials for cells in the neutrophil window include:

• Cells of the granulocytic series (from promyelocytes to mature neutrophils).
• Acute promyelocytic leukaemia (classical hypergranular form).
• Mast cell leukaemia
