What do leukocytosis of 21000 mean?

Leukocytosis refers to an abnormally high white blood cell count. A leukocytosis of 21,000 indicates a white blood cell count of 21,000 cells per microliter of blood. This is significantly higher than the normal range, which typically falls between 4,500 and 11,000 cells per microliter.

Leukocytosis can be caused by various underlying medical conditions, such as infections, inflammatory diseases, certain medications, or even stress. It is important to determine the cause of leukocytosis in order to receive appropriate medical treatment.

If you have a leukocytosis of 21,000, your doctor may recommend further tests and evaluation to identify the underlying cause and provide you with the necessary treatment. It is crucial to follow your doctor's advice and seek medical care promptly if you have concerns about your blood test results or experience any other symptoms or health problems.
