What it means
A complete blood count (CBC) is one of the most common blood tests ordered by doctors. It measures the number and types of cells in your blood, including red blood cells (which carry oxygen), white blood cells (which fight infection), and platelets (which help blood clot). A laboratory technician draws a small sample of blood from a vein in your arm. Results help doctors diagnose anemia, infections, bleeding disorders, and certain cancers. Your doctor reviews the counts alongside normal reference ranges to decide if further testing or treatment is needed.
