    Notes: Monocyte nuclear and cytoplasmic morphology can be highly variable.1

    Nucleus-to-Cytoplasm Ratio: Variable 2

    Nucleoli: Not visible 2

    Nucleus:1,2

    Variable shapes (Folds, kidney shaped)

    Loose, lacy, violet chromatin

    Cytoplasm:1,2

    Blue-gray cytoplasm (Ground glass appearance due to fine, diffuse granules)

    May have pseudopods

    May have vacuoles

    Normal % in Bone Marrow: 2%2

    Normal % in Peripheral Blood: 3-11%2
