Final answer:
The complete blood count (CBC) reports on blood cell counts, providing critical data on health indicators like infection risk or anemia, not liver function, kidney function, or heart activity.
Step-by-step explanation:
The complete blood count (CBC) ordered for Mrs. Jones during her routine yearly physical exam will provide information about blood cell counts. This test evaluates different types of blood cells, such as red blood cells, white blood cells, and platelets. A CBC can detect a wide array of conditions, from anemia and infection to many other diseases.
The CBC is different from tests that measure liver function or kidney function, and it does not check the heart's electrical activity. Instead, it informs about the composition and concentration of blood cells, which can indicate issues such as an infection if there is a high white blood cell count.
Blood tests like the CBC are crucial for diagnosing and monitoring many medical conditions and are often a routine part of a physical examination.
