Absolute Neutrophil Count

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.
