What is Leukocytosis?
References:

Content: The white blood cells (WBC) or leukocytes play an important role in the body’s immune system to fight against infections. Various types of WBCs include the neutrophils, lymphocytes, monocytes, eosinophils and basophils. The neutrophils are the most numerous, followed by the lymphocytes. These cells are produced by the bone marrow. A condition with an increased count of more than 11,000 leukocytes per cubic mm of adult human blood is termed as leukocytosis. ( 1 ✔)
The WBC count is often increased as a reaction of the bone marrow to infection or inflammation. Certain bacterial and viral infection can trigger leukocytosis. Leukocytosis is also related to strong immune reactions like asthma and other allergy attacks. Some of the most serious and life-threatening cases of leukocytosis are associated with the diseases of the bone marrow. An elevated WBC count of greater than 30,000 per cubic mm of the adult human blood could indicate an underlying bone marrow disorder including leukemia or blood cancer.
