A CBC blood test stands for Complete Blood Count. It is a common blood test that measures the number and size of the different cells in your blood, including:
* Red blood cells (RBCs): Carry oxygen.
* White blood cells (WBCs): Fight infection and disease.
* Platelets: Help your blood clot.
* Hemoglobin and Hematocrit (measures related to red blood cells).
Doctors use a CBC to check your overall health, help diagnose a wide range of conditions like anemia, infection, and some cancers, or monitor existing conditions or treatments.
