What does leukocytosis usually indicate?
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.
Does leukocytosis always mean infection?
Leukocytosis (WBC > 10,000/mm 3) can indicate infection, inflammation (possibly from allergies), tissue damage or burns, dehydration, thyroid storm, leukemia, stress, or steroid use. The degree of leukocytosis depends on the severity of the disorder, the patient’s age and general health, and bone marrow health.
Does leukocytosis mean cancer?
When these white blood cells are above the normal range, it is called leukocytosis. Common causes of leukocytosis include having an infection, but it also can occur if a person has had bone tumors or leukemia.
What is the normal range of differential leukocyte count?
Reference Range Reference ranges for differential white blood cell counts are as follows : Neutrophils – 2500-8000 per mm3 (55-70%) Lymphocytes – 1000-4000 per mm3 (20–40%) Monocytes – 100-700 per mm3 (2–8%)
Can leukocytosis lead to leukemia?
Excessive numbers of white blood cells are most often due to the response of normal bone marrow to infection or inflammation. In some instances, leukocytosis is a sign of more serious primary bone marrow disease (leukemias or myeloproliferative disorders).
How serious is leukocytosis?
Having white blood cell levels above this range can be a sign of leukocytosis. If you have WBC counts between 50,000 and 100,000 per microliter of blood, it may mean that you have a severe infection, organ rejection, or a solid tumor.
What is a normal leukocytes reading?
The normal number of WBCs in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs.
