Learn More about the Complete Blood Count Screening


What is a complete blood count? 

The human body is primarily made up of water and cells. Some very special and important cells, however, move throughout the body by traveling (circulating) in the blood. These circulating cells provide oxygen to all of the stationary cells in the body, help fight infection throughout the body, and help stop bleeding after an injury. The complete blood count, or CBC, is a lab test that provides information about the cells circulating in your body.


What is a complete blood count used for?

A complete blood count can help to provide information about your health. Some of the uses of this test are as follows:

  • Provide basic information about your health

  • Detect a health condition before you have any symptoms

  • Confirm that a health condition exists

  • Identify the causes of your symptoms

  • Find out if your medicine is working

  • Rule out a disease

  • Establish a baseline that can be used for comparison with future test results

Who should get tested?

If you or your doctor wish to check basic information about your health, check for a health condition, or monitor a health condition or medication that you are taking, then a complete blood count test may be right for you.
