Complete blood count

A complete blood count (CBC) is a blood panel requested by a doctor or other medical professional that gives information about the cells in a person's blood. The test reports the amounts of white blood cells, red blood cells, and platelets, the concentration of hemoglobin in the blood, and the hematocrit, which is the percentage of the blood that is made up of red blood cells. The red blood cell indices, which describe the average size and hemoglobin content of red blood cells, are also reported, and a white blood cell differential, which counts the different types of white blood cells in the blood, such as neutrophils, eosinophils, basophils, monocytes, and lymphocytes, may be performed.
