A complete blood count (CBC ) cALC ulates several parameters related to blood cell counts. It typically includes the measurement of red blood cells (RBC s), white blood cells (WBCs), hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and platelets. These measurements provide valuable information about different aspects of blood health. RBC s carry oxygen, WBCs help fight infection, hemoglobin carries oxygen within RBC s, hematocrit measures the percentage of blood made up of RBC s, MCV assesses the average size of RBC s, MCH measures the amount of hemoglobin in RBC s, MCHC measures the concentration of hemoglobin in RBC s, and platelets are involved in blood clotting. The CBC helps evaluate overall health, diagnose various conditions, and monitor treatment responses.
