What is the primary purpose of a Complete Blood Count (CBC)?

The primary purpose of a Complete Blood Count (CBC) is to analyze the formed elements of blood. A CBC provides valuable information regarding the different types of cells present in the bloodstream, such as red blood cells, white blood cells, and platelets.

This test helps assess various health conditions, including anemia, infections, and many other medical issues. The measurements obtained can reveal crucial information about a patient's overall health status, guiding further diagnostic and therapeutic decisions.

The other options relate to different types of assessments that do not fall under the scope of a CBC. For instance, measuring blood glucose levels pertains to diabetes management, assessing electrolyte balance is critical for understanding hydration and kidney function, and evaluating liver function typically involves a separate panel of tests focused on liver enzymes and functions. Each serves an important role but is distinct from the purpose of a CBC, which specifically focuses on the cellular components of blood.
