Blood Test: Complete Blood Count

Text D. Blood Test: Complete Blood Count (CBC).

(CBC) is a common blood test that evaluates the three major types of cells in the blood: red blood cells, white blood cells, and platelets. A CBC may be done as a part of a routine checkup, or if you or your child is feeling more tired than usual, or has an infection, or has unexplained bleeding. No special preparations are needed. The CBC can also test for loss of blood, abnormalities in the production or destruction of blood cells, acute and chronic infections, allergies, and problems with blood clotting.

Red blood cells: The CBC's measurements of red blood cell (RBC) count, hemoglobin (the oxygen-carrying protein in RBCs), and mean (red) cell volume (MCV) provides information about the RBCs, which carry oxygen from the lungs to the rest of the body. These tests are usually done for anemia, a common condition that occurs when the body has insufficient red blood cells. Strangely, when there is an excess of red blood cells, the tissues may also suffer from lack of oxygen. In this case the difficulty is that with a high population of red cells the blood becomes syrupy and moves so slowly that it cannot deliver its oxygen quickly.

White blood cells: The white blood cell (WBC) count measures the number of WBCs (also called leukocytes) in the blood. The WBC differential test measures the relative numbers of the different kinds of WBCs in the blood. WBCs, which help the body fight an infection, are bigger than red blood cells and there are far fewer of them in the bloodstream. An abnormal WBC count may indicate an infection, inflammation, or other stress in the body. For example, a bacterial infection can cause the WBC count to increase, or decrease.

Platelets: The smallest blood cells, platelets play an important role in blood clotting and the prevention of bleeding. When a blood vessel is damaged or cut, platelets clump together and plug the hole until the blood clots. If the platelet count is too low, a person can be in danger of bleeding in any part of the body.
