Leukocytosis is a medical term used to describe a condition characterized by an increase in the number of white blood cells (leukocytes) in the blood circulation. White blood cells play a crucial role in the body's immune system, as they help combat infections and foreign substances. This condition typically occurs as a response to various factors, such as infections, inflammation, trauma, certain medications, or specific diseases.
Leukocytosis is commonly diagnosed through a blood test that measures the white blood cell count. The normal range of white blood cells in adults is typically between 4,500 and 11,000 cells per microliter of blood. When the white blood cell count exceeds this range, exceeding 11,000 cells per microliter, it is considered leukocytosis.
There are two main types of leukocytosis: reactive leukocytosis and neoplastic leukocytosis. Reactive leukocytosis occurs as a response to certain conditions, such as infections, inflammation, or physical stress. On the other hand, neoplastic leukocytosis is often associated with cancer, where abnormal white blood cells are excessively produced.
The symptoms of leukocytosis may vary depending on the underlying cause. Commonly observed symptoms include fatigue, fever, sweating, enlarged lymph nodes, and general malaise. The treatment for leukocytosis depends on the cause; if an infection is present, antibiotics or antiviral drugs might be prescribed, while underlying medical conditions or medications may need to be addressed or adjusted.
It is important for a healthcare professional to diagnose and treat leukocytosis promptly, as it can indicate an underlying health issue or be a sign of an ongoing infection. Early detection and appropriate management can help prevent complications or further health
