What is a normal white blood cell count for a female?

The normal white blood cell count for a female is between 3.5 and 10.5 billion cells per liter, as stated by Mayo Clinic. Some doctors measure this in deciliters, making a normal count 3,500 to 10,500 per deciliter.

Doctors often order a complete blood count, or CBC, because they are searching for abnormalities in the blood stream, such as too many white blood cells, which may be a sign of infection or inflammation.

A low white blood count is often caused by an autoimmune disorder, cancer or issues in the bone marrow. A white blood count that is too high may indicate an immune system disorder or a reaction to medication.
