Full blood counts, also known as complete blood counts or CBCs, refer to a comprehensive lab test that measures the various components of the blood. The test is often used to evaluate overall health or diagnose certain conditions. Several similar terms are used to refer to this test, including blood panel, hemogram, or full blood examination. Other related tests include white blood cell count, red blood cell count, hemoglobin count, and platelet count. Understanding the results of a full blood count can provide valuable information about a person's overall health and help healthcare providers develop a plan for treatment if necessary.
