How is severity of neutropenia graded?

By William Aird

  • Mild 1-1.5 × 109/L; does not impair host defense.
  • Moderate 0.5-1 × 109/L; slight increased risk of infection if other arms of immune system also impaired.
  • Severe < 0.5 × 109/L; increased risk of infection in most patients.
  • Agranulocytosis ≤ 0.2 × 109/L; risk of severe, life-threatening infections.
