Differentiating Leukocytosis from Other Diseases

• Leukocytosis is defined as an elevated white blood cell (WBC) count greater than 11,000 per mm3 (11.0 × 109 per L).
• The most common type of leukocytosis is neutrophilia.
  • Neutrophilia can be defined as an increase in the absolute number of mature neutrophils to greater than 7,000 per mm3 [7.0 × 109 per L].
