Definition:
A blood test done to check the levels of certain cells in the blood. In lung cancer, a complete blood count (CBC) is often checked at the time of diagnosis, and to follow the levels of blood cells during treatment.
A CBC tests the levels of red blood cells (RBCs), cells that carry oxygen through the body; white blood cells (WBCs), cells that fight infection; and platelets, cells that help blood to clot.
A low level of red blood cells (RBCs) is known as anemia; white blood cells (WBCs), leukopenia; and platelets, thrombocytopenia.
