What is the primary purpose of a CBC test?

The primary purpose of a complete blood count (CBC) test is to diagnose several diseases. A CBC is a comprehensive screening test that evaluates the components and features of blood, including red blood cells, white blood cells, and platelets. By analyzing these components, healthcare providers can gain valuable insights into a patient's overall health and detect a wide range of conditions, from anemia and infections to blood cancers.

The CBC provides specific measurements, such as hemoglobin levels, hematocrit, white blood cell count, and platelet count, which help identify abnormalities in the blood that may indicate underlying diseases or health issues. Given its broad diagnostic capabilities, it is a fundamental tool used in various medical settings to assess health status and guide further testing or treatment plans.
