____ is used to determine the volume percentage of red blood cells in whole blood.

○ spectrin

○ hematocrit

○ hematopoiesis

○ hemocytometer

Explanation:

To determine the volume percentage of red blood cells in whole blood, we analyze the options:

• Spectrin: A protein in red blood cells, not for volume percentage.
• Hematocrit: Defined as the volume percentage of red blood cells in whole blood.
• Hematopoiesis: The process of blood cell formation, not for measuring volume percentage.
• Hemocytometer: A device to count blood cells, not specifically for volume percentage of RBCs.

So the correct term is Hematocrit.

Answer:

B. Hematocrit
