When to Use

Clinical Use

Evaluating the degree of neutropenia.

Assessing infection risk in patients on chemotherapy or with hematologic disorders.

Determining the need for antifungal/antibacterial prophylaxis or G-CSF administration.

Clinical Pearls

Grading Neutropenia

ANC Range (cells/µL)	Severity	Clinical High Level Note
≥ 1500	Normal/Mild	No increased risk of infection.
1000 - 1500	Mild	Minimal risk.
500 - 1000	Moderate	Increased risk of infection.
< 500	Severe	Significant risk of life-threatening infection.
< 200	Agranulocytosis	Extremely high risk; medical emergency.
