Complete Blood Count (CBC)
Say: com-pleet blud cownt
Blood is made up of different parts, such as red blood cells, white blood cells, and platelets. Red blood cells are like trucks zooming around on the blood vessel highway in your body, carrying oxygen to the rest of your body. White blood cells are the warriors of the blood, defending your body against germs that try to make you sick. And platelets are like repair people because when you get a cut, platelets stick together to form a plug to stop bleeding. Doctors sometimes do blood tests to count how many of each type of blood cell you have. In a complete blood count, the numbers of red blood cells, white blood cells, and platelets in your blood get counted.
