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

The primary purpose of performing a Complete Blood Count (CBC) is to detect infections or blood disorders. A CBC is a comprehensive blood test that evaluates various components of the blood, including red blood cells, white blood cells, and platelets. It can reveal a range of information about health status, including signs of anemia, infection, and other hematological conditions.

For instance, an elevated white blood cell count may indicate an ongoing infection or acute inflammation, while a low count could suggest a risk for infection. Similarly, abnormalities in red blood cell counts can signal conditions such as anemia. The insights gained from a CBC are crucial for diagnosis and monitoring of various medical conditions, enabling healthcare providers to make informed decisions regarding a patient's treatment and care.

While tests related to liver function, cholesterol levels, and blood typing are important, they serve distinct purposes and are not encapsulated by the broader scope of a CBC. Each of these tests targets specific health aspects, whereas the CBC provides a holistic view of the patient's blood health, making it a fundamental component of routine medical evaluations.
