Information
Absolute Neutrophil Count (ANC) is a key measure of immune function, calculated from the total white blood cell count and the percentage of neutrophils (including both segmented neutrophils and bands). It is used to assess the risk of infection, particularly in patients undergoing chemotherapy, as a low ANC (neutropenia) can indicate a higher risk of infection. The ANC is guides treatment decisions, such as the initiation of antibiotics or the modification of chemotherapeutic regimens and is an important in the management of patients with conditions that affect white blood cell production or function.

Interpretation & Suggested actions
- ANC < 0.5 ×10³/µL — Severe neutropenia. High infection risk. Consider urgent clinical review and protective isolation; discuss empiric antibiotics per local protocols.
- 0.5 — 1.0 ×10³/µL — Moderate neutropenia. Increased infection risk; consider close monitoring and infection precautions.
- 1.0 — 1.5 ×10³/µL — Mild neutropenia. Low-moderate risk; observe and repeat CBC as indicated.
- >= 1.5 ×10³/µL — Generally considered normal neutrophil count for adults.
