What else might my complete blood count (CBC) tell me?

ANSWER

Your complete blood count can reveal more information about your health, depending on what your doctor orders. Your doctor will know whether you have an illness or blood condition by measuring the following:

  • MCH (mean corpuscular hemoglobin). This telld you how much hemoglobin (a protein) is in your typical red blood cell. It carries oxygen to your organs and tissues. 
  • MCHC (mean corpuscular hemoglobin concentration). This measures the concentration of hemoglobin in a certain amount of blood. It is calculated by dividing the Hgb by Hct.
  • RDW (red cell distribution width). This tells you how your much your red blood cells vary in size.
  • Reticulocyte Count. This test measures the number of new red blood cells in your body.
  • MPV (mean platelet volume). This measures the average size of the platelets in your blood.
  • PDW (platelet distribution width). This tells you how much your platelets vary in size.
  • White Blood Cell Differential. There are five types of white blood cells. This test shows how many of each type you have: neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
