Which term refers to the process of separating solids from plasma in the blood?

The process of separating solids from plasma in the blood is termed hematocrit. This term specifically refers to the percentage of blood volume that is made up of red blood cells. In a laboratory setting, hematocrit is determined by spinning a sample of blood in a centrifuge, which causes the denser cellular components to settle at the bottom of the container while the plasma remains on top. The measurement of hematocrit is important in medical diagnosis, as it helps assess conditions like anemia or polycythemia, which can impact a patient's health and treatment options.

The other terms relate to different aspects of blood or its components. Hematoma refers to a localized collection of blood outside of blood vessels, typically caused by an injury. Glucose is a type of sugar found in the blood that serves as a primary energy source for the body's cells and is not related to the separation of blood components. Hemoglobin is a protein found in red blood cells that is responsible for carrying oxygen; while it is a significant part of the blood, it does not describe the process of separation itself. This understanding highlights why hematocrit is the correct choice in this context.
