ANC Calculator
ANC from WBC × (segs% + bands%). Click any i for detail.
CBC inputs

Immature neutrophils; use 0 if not reported. |
How to use this calculator
- Enter WBC in ×10³/µL.
- Enter segs% and bands%.
- Read ANC in cells/µL and ×10³/µL.
- Use your lab’s reference range with a clinician.
Results explained
Absolute neutrophil count multiplies the WBC by the neutrophil fraction (segmented + bands). Neutropenia thresholds (for example <1500/µL) are teaching cues only — oncology protocols differ.
Quick reference: ANC
ANC (/µL) = WBC×1000×(segs%+bands%)/100.
| Item | Detail |
|---|---|
| Equiv. form | ANC (×10³/µL) = WBC × (segs+bands)/100 |
| Bands missing | Use 0 |
| Automated diffs | Follow the lab’s neutrophil % |
| Chemo thresholds | Protocol-specific |
Educational only — not a chemotherapy clearance tool.
How the estimate is built
ANC = WBC × 10³ × (segs + bands) / 100 cells per µL.
Example scenario
WBC 6.5, segs 55%, bands 3% → ANC 3,770/µL.
FAQ
Include metas/myelocytes?
Some manual diffs do; this page uses segs + bands only.
SI WBC units?
Enter ×10³/µL (same as ×10⁹/L numerically for WBC).
What is severe neutropenia?
Often <500/µL in teaching texts — confirm clinically.
Absolute vs relative?
ANC is absolute; % neutrophils alone is relative.
