Normal range: 4.5 – 11.0 K/uL
Mature neutrophils, normal: 50–70%
Immature neutrophils, normal: 0–10%
Formula
Result is in K/uL (thousands of cells per microliter).

Summary
The ANC (Absolute Neutrophil Count) Calculator computes the total number of neutrophils in your blood from a CBC with differential. It combines segmented neutrophils (segs) and band neutrophils (bands) to give a precise ANC value. Clinicians use ANC to diagnose neutropenia, guide chemotherapy dosing decisions, and stratify infection risk in immunocompromised patients.
How it works
- Enter your White Blood Cell (WBC) count in thousands per microliter (K/uL).
- Enter the percentage of segmented neutrophils (segs/polys) from your differential.
- Optionally enter the percentage of band neutrophils (immature neutrophils).
- Click Calculate to compute the ANC using the formula: ANC = WBC × (Segs% + Bands%) / 100.
- Review your ANC value and the corresponding neutropenia severity classification.
Use cases
- Monitor neutropenia during chemotherapy or radiation therapy.
- Determine whether a patient is safe to receive myelosuppressive treatment.
- Assess infection risk in patients with fever and low white cell counts.
- Track bone marrow recovery after stem cell transplantation.
- Evaluate congenital or cyclic neutropenia severity.
- Guide antibiotic prophylaxis decisions in oncology settings.
- Educational use in nursing and medical training programs.
- Quick bedside reference for interpreting CBC with differential results.
