Why the percentage alone isn't enough
A white blood cell differential reports neutrophils as a percentage, but the actual number of neutrophils available to fight infection depends on total WBC count too - ANC combines both figures into the clinically actionable number.
Worked example
For a WBC count of 5,000 with 50% neutrophils and 5% bands:
ANC = 5000 x ((50 + 5) / 100) = 2,750.0 cells/microL (Within typical normal range)
| ANC (cells/microL) | General Category |
|---|---|
| Below 500 | Severe neutropenia - high infection risk |
| 500-999 | Moderate neutropenia |
| 1,000-1,499 | Mild neutropenia |
| 1,500+ | Typical normal range |
ANC is especially important in oncology, where chemotherapy-induced neutropenia significantly raises infection risk and often directly determines treatment timing and precaution decisions.
