This is a blood test that counts the number of blood cells in a sample of blood, usually expressed as the number of cells per liter of blood. If the total number of red blood cells is low, this is known as anemia. There are various types of white blood cells and each is accounted for by this process and can help in the diagnosis of certain diseases. This test is part a “minimum database” of information that is needed to screen for underlying disease or to monitor a sick patient.
