A complete blood count (CBC) is a panel of tests that are often ordered together to give your healthcare provider an overview of your general health. The CBC can help detect a variety of conditions, including anemia, infection, and leukemia.
The CBC includes:
– Red blood cell (RBC) count: This measures the number of red blood cells in your blood. Red blood cells carry oxygen to the body’s tissues.
– White blood cell (WBC) count: This measures the number of white blood cells in your blood. White blood cells help fight infection.
– Hemoglobin and hematocrit: These tests measure the amount of hemoglobin in your blood. Hemoglobin is the part of the red blood cell that carries oxygen. The hematocrit is the percentage of your blood that is made up of red blood cells.
– Platelet count: This measures the number of platelets in your blood. Platelets help with blood clotting.
The CBC is often ordered as part of a routine physical exam or when your healthcare provider suspects you may have a condition that is affecting your blood cells.
