Complete Blood Count Whole blood is made up of various types of cells suspended in a liquid called plasma. The complete blood count (CBC) is an inventory of the different cellular components of the blood: red blood cells, white blood cells, and platelets. Blood cell counts are typically reported as the number of cells in a cubic millimeter of blood (cells/mm3) or as a percentage of all blood cells.
