A white blood cell (WBC) scan is an imaging test that uses a radioactive material called a tracer. It looks for infection or inflammation in the body. It is a type of nuclear scan.
A complete blood count (CBC) gives important information about the kinds and numbers of cells in the blood, especially red blood cells, white blood cells, and platelets. A CBC helps your doctor check any symptoms, such as weakness, fatigue, or bruising, you may have.A CBC also helps him or her diagnose conditions, such as anemia, infection, and many other disorders. A CBC test usually includes: 1  White blood cell (WBC, leukocyte) count.2  White blood cells protect the body against infection. 3  If an infection develops, white blood cells attack and destroy the bacteria, virus, or other organism causing it. 4  White blood cells are bigger than red blood cells but fewer in number. White blood cell types (WBC differential). 2  The major types of white blood cells are neutrophils, lymphocytes, monocytes, eosinophils, and basophils. 3  Immature neutrophils, called band neutrophils, are also part of this test. 4  Each type of cell plays a different role in protecting the body.
