A test that evaluates the numbers and types of cells in the blood is called what?

• A. Blood smear
• B. Complete blood count
• C. White blood cell differential
• D. Coagulation test

Answer: (B)

A Complete Blood Count (CBC) is a comprehensive test that provides valuable information about the blood's cellular components. It evaluates the numbers and types of various blood cells, including red blood cells, white blood cells, and platelets. The CBC helps in diagnosing a range of conditions, from anemia to infections and many other hematological disorders. The CBC includes measurements such as hemoglobin levels, hematocrit, and the total number of white blood cells, which can be further analyzed to assess the types of white blood cells present. This makes it a fundamental tool in clinical diagnostics, enabling practitioners to gain insights into a patient's overall health status and guide further testing or treatment options. Other options provided, like a blood smear and white blood cell differential, are specific components or types of analyses within the broader context of the complete blood count, but they do not encompass the full range of analysis that a CBC provides. A coagulation test, on the other hand, focuses specifically on the blood's ability to clot and does not evaluate the numbers and types of cells in the blood.
