What is a normal ANC value?

A normal ANC is generally between 1,500 and 8,000 cells per microliter (1.5–8.0 K/uL). Values below 1,500 indicate neutropenia, and values below 500 indicate severe neutropenia with high infection risk.

What is the ANC formula?

ANC = WBC (K/uL) × (Segs% + Bands%) ÷ 100. The result is in thousands of cells per microliter (K/uL). Multiply by 1,000 for cells/uL.

Why are bands included in the ANC calculation?

Band neutrophils are immature neutrophils that are still capable of fighting infection. Including them gives a more complete picture of the body's neutrophil reserve, especially during acute infections or recovery from bone marrow suppression.

What ANC level requires hospitalization?

An ANC below 500 cells/uL (0.5 K/uL) — severe neutropenia — typically requires close monitoring and often hospitalization, especially if accompanied by fever. Clinicians call this febrile neutropenia, which is a medical emergency.
