A complete blood count (CBC) test measures many aspects of your blood, including:
✔️Red blood cells (RBC): The number of red blood cells in your blood, which carry oxygen from your lungs to the rest of your body
✔️White blood cells (WBC): The total number of white blood cells in your blood, which fight infections and other diseases.
✔️Hemoglobin: The amount of hemoglobin in your blood, a protein in red blood cells that carries oxygen
✔️Hematocrit: The percentage of your blood that is made up of red blood cells
✔️Platelets: The number of platelets in your blood, which help your blood clot to stop bleeding
✔️Mean corpuscular volume (MCV): The average size of your red blood cells
A CBC can help a doctor monitor and diagnose a variety of conditions, including anemia, infection, and leukemia. Abnormal results can be caused by infections, medications, anemia, and cancer.
