A Complete Blood Count (CBC) is a fundamental and frequently performed blood test that provides essential insights into an individual's overall health. It evaluates the composition and health of different blood cell types, offering valuable information to healthcare professionals for diagnostic purposes and monitoring various medical conditions. The CBC typically includes the assessment of red blood cells (RBCs), white blood cells (WBCs), and platelets. Hemoglobin and hematocrit levels, which reflect the oxygen-carrying capacity of the blood, are also measured. White blood cell counts help identify potential infections or immune system disorders, while platelet counts are crucial for assessing blood clotting abilities.
