What does Hematocrit (Hct) measure in blood?

• A. Volume of white blood cells
• B. Volume of packed red blood cells
• C. Level of plasma proteins
• D. Amount of oxygen transported

Answer: (B)

Hematocrit (Hct) measures the volume of packed red blood cells in a given volume of blood. It is typically expressed as a percentage and provides essential insights into a patient's blood composition, particularly regarding red blood cell production and overall blood viscosity. A higher hematocrit value indicates a higher proportion of red blood cells to plasma, which can be informative in diagnosing conditions such as polycythemia or dehydration. Conversely, a low hematocrit can suggest anemia, fluid overload, or other hematological disorders. Understanding hematocrit is crucial for evaluating a patient’s overall health and for diagnosing potential medical issues related to red blood cell counts.
