FIGURE 5-10A Neutrophilic band.

SIZE: 10-15 mm
NUCLEUS: Constricted but no threadlike filament;
indentation is more than 50% of the width of a
hypothetical round nucleus
NOTE: Chromatin must be visible in constriction;
may be folded over
Nucleoli: Not visible
Chromatin: Coarse, clumped
CYTOPLASM: Pale blue to pink
Granules:
Primary: Few
Secondary: Abundant
N/C RATIO: Cytoplasm predominates
Reference Interval:
Bone Marrow: 17% to 33%
Peripheral Blood: 0% to 5%
