Percentage Neutrophils %
Percentage Bands %
WBC (per 1000. Usually reported as "8.4"; do not enter 8400.) cells/ml
Absolute Neutrophil Count cells/ml

Absolute Neutrophil Count = 10 * WBC count in 1000s * (% PMNs + % Bands)

Neutropenia: ANC < 1500 cells / mm3

  • Mild Neutropenia: 1000-1500 cells / mm3
  • Moderate Neutropenia: 500-999 cells / mm3
  • Severe Neutropenia: < 500 cells / mm3

Filgrastim (Neupogen), aka G-CSF, can stimulate production of neutrophils.
