  • Antibiotics may be given to treat or prevent an infection caused by bacteria.
  • Uric acid medicine decreases the amount of uric acid in your body. Uric acid is a chemical found in your blood. It may also help prevent more damage to your cells.
  • Steroids decrease inflammation and may help decrease the number of WBCs in your blood.
  • Antacids help decrease the acid in your urine during treatment for leukocytosis.
  • IV fluids may help to give you extra fluid and give you electrolytes.


  • Blood tests will show the number and shape of your WBCs. They will show if you have too much of one type of WBC. They may also help to find the cause of your leukocytosis.
  • A chest x-ray may be done to test your lung and heart function.
  • An echocardiogram is a type of ultrasound. Sound waves are used to show the structure, movement, and blood vessels of your heart.
  • Lung function tests may be done to show healthcare providers how well your lungs are working.
  • A bone marrow biopsy is a sample of bone marrow that is removed and sent to a lab for tests.


  • Leukapheresis is a procedure to decrease the number of WBCs. Blood is taken from your body through an IV. The WBCs are separated and removed. Your blood, without the WBCs, may be given back to you, or sent to a lab for tests.
  • A blood transfusion may be needed to give you blood or parts of blood.


Treatment may cause bleeding, muscle cramps, or sepsis (a serious blood infection). Even with treatment, your leukocytosis may get worse. Without treatment, your leukocytosis may get severe and cause bleeding or damage to your lungs or kidneys.
