Why do I need a white blood count?
You may need this test if you have signs of an infection, inflammation, or autoimmune disease. Symptoms of infection include:
Fever
Chills
Body aches
Headache
Symptoms of inflammation and autoimmune diseases will be different, depending on the area of inflammation and type of disease.
You may also need this test if you have a disease that weakens your immune system or are taking medicine that lowers your immune response. If the test shows your white blood count is getting too low, your provider may be able to adjust your treatment.
Your newborn or older child may also be tested as part of a routine screening, or if they have symptoms of a white blood cell disorder.
