Clinical takeaway

< 0.5 ×10⁹/L is severe neutropenia.

When to use

Calculate ANC and grade neutropenia.

How it works

ANC = WBC × (segmented neutrophils% + bands%) / 100. < 1.5 mild, < 1.0 moderate, < 0.5 severe (×10⁹/L).

Key points

  • < 0.5 ×10⁹/L is severe neutropenia.
  • Fever with neutropenia: see IDSA 2010 (PMID 21258094).
  • Include band forms in the calculation.
