What is a CBC test, and why is it important?

A Complete Blood Count (CBC) test is a common blood test that evaluates the health and function of various blood components, including red blood cells (RBC), white blood cells (WBC), hemoglobin, hematocrit, and platelets. It's crucial for diagnosing conditions like anemia, infection, leukemia, and monitoring overall health. The test gives doctors valuable information about the immune system, oxygen transport, and blood clotting. Regular CBC tests are important for individuals undergoing treatment for chronic illnesses or those showing signs of infections or abnormal fatigue, as early detection can help prevent complications. Results from a CBC test can guide further diagnostic tests or treatment plans.
