Complete blood count (CBC) with differential

Complete blood counts are drawn during treatment very frequently. Physicians monitor complete blood county to determine how well a patient's bone marrow is functioning and if the patient is tolerating treatment.

During this test, blood is drawn to measure the number of red blood cells, white blood cells and platelets in the blood. The amount of hemoglobin (substance in the blood that carries oxygen) and the hematocrit (the amount of whole blood that is made up of red blood cells) are also measured. The differential will count the different types of white blood cells that may be present.
