A complete blood count (CBC) is a test that measures the cells that make up your blood: red blood cells, white blood cells, and platelets.
Your doctor may order a CBC as part of a routine check-up or to:
* Check for anemia
* See if you have another health issue or to explain symptoms like weakness, fever, bruising, or feeling tired
* Keep an eye on a blood condition you already have
* See how medications or treatments like chemotherapy are affecting your blood
Instructions: No fasting required
