What does CBC evaluate?

What does CBC evaluate?

• A. Blood plasma
• B. Blood cells
• C. Coagulation factors
• D. Electrolytes

Answer: (B)

The main concept is that a complete blood count focuses on the cellular components of blood. It measures red blood cells, white blood cells, and platelets, and provides related data such as hemoglobin, hematocrit, and cell-size indices. This information helps detect anemia, infection or inflammation, and platelet or bone-marrow problems. The other options refer to components in plasma (electrolytes) or to coagulation factors, which are assessed with different tests like electrolyte panels and coagulation studies. So the CBC is specifically about evaluating the blood cells themselves.
