Leukocytosis is a medical condition characterized by an abnormally high number of white blood cells in the blood. White blood cells, also known as leukocytes, are a crucial component of the immune system, responsible for fighting infections and diseases. Leukocytosis can be caused by various factors, including infections, inflammation, stress, and certain medical conditions such as leukemia, lymphoma, and autoimmune disorders.

The normal range of white blood cells in the blood is typically between 4,000 and 11,000 cells per microliter. Leukocytosis is defined as a white blood cell count greater than 11,000 cells per microliter. This condition can be further classified into two types: reactive and neoplastic. Reactive leukocytosis occurs in response to infections or inflammation, and the elevated white blood cell count usually returns to normal once the underlying cause is treated. Neoplastic leukocytosis, on the other hand, is associated with cancerous conditions and does not resolve with treatment of the underlying cause.

Leukocytosis can be detected through a complete blood count (CBC) test, which is a routine blood test that measures various components of the blood, including white blood cells. The diagnosis of leukocytosis typically involves a thorough medical history, physical examination, and additional tests to identify the underlying cause. Treatment for leukocytosis depends on the underlying condition and may include antibiotics for infections, anti-inflammatory medications for inflammation, or chemotherapy for cancerous conditions. In some cases, leukocytosis may be a benign finding with no specific treatment required.
