White Blood Count (WBC, Leukocyte count)


A WBC count measures the number of white blood cells in a sample of blood. It is a valuable diagnostic tool for a number of diseases that is usually ordered as part of a complete blood count

This test is normally performed to detect an infection or inflammation.

A normal white blood cell count ranges from 4,500 to 10,000 cells/mcl (cells per microliter) of blood.

Abnormally low numbers of white blood cells may be caused by:

  • bone marrow failure
  • a bone marrow tumor
  • a substance in the body that is toxic to these cells
  • collagen-vascular diseases, such as rheumatoid arthritis or systemic lupus erythematosus
  • liver disease
  • spleen disease
  • radiation

Abnormally high numbers of white blood cells may be caused by:

  • allergy
  • emotional or physical stress
  • infectious diseases
  • inflammatory diseases
  • leukemia
  • tissue damage
