What is leukocytosis?
A higher-than-normal number of white blood cells is called leukocytosis. Leukocytes usually increase in number when they are doing their job, but there are some other conditions that can cause an increase.
What is the range for leukocytosis?
Leukocytosis is the broad term for an elevated white blood cell (WBC) count, typically above 11.0×10^9/L, on a peripheral blood smear collection. The exact value of WBC elevation can vary slightly between laboratories depending on their ‘upper limits of normal’ as identified by their reference ranges.
What is leukocytosis and leukopenia?
Definition. Leukocytosis is an elevation in the absolute WBC count (>10,000 cells/μL). Leukopenia is a reduction in the WBC count (<3500 cells/μL).

What is the difference between leukocytosis and leukopenia?
Leukocytosis is an elevation in the absolute WBC count (>10,000 cells/μL). Leukopenia is a reduction in the WBC count (<3500 cells/μL).
What are some causes of leukocytosis?

How does leukocytosis occur?
Leukocytosis is a condition in which the white cell (leukocyte count) is above the normal range in the blood. It is frequently a sign of an inflammatory response, most commonly the result of infection, but may also occur following certain parasitic infections or bone tumors as well as leukemia.
What is high leukocytosis?
High white blood cell count, also known as leukocytosis, can indicate a range of conditions including infections, inflammation, bodily injury and immune system disorders. A complete blood count (CBC) is usually performed to check for leukocytosis.
What means high lymphocytes?
