Leukocytosis Absolute

**Leukocytosis** is an increase in the number of leukocytes per unit volume of blood. The number of leukocytes ranges from 4–6 × 109/L (normal) to 20–24 × 106/L with B 1st degree and up to 50-21 × 1/L with 3rd degree A. Deviations from the norm are not a diagnostic sign if the deviation occurs only within the range of 0.8–3.0 × 1.
