What does hemolysis refer to in laboratory terminology?

• A. Preventing clotting of blood
• B. Isolating platelets
• C. Breaking down blood cells
• D. Reducing the number of clots

Answer: (C)

Hemolysis means breaking down blood cells, especially red blood cells, in a sample. In lab terms, it’s rupture of the cells that releases hemoglobin into the surrounding fluid, which often gives plasma a pink or red tint and can distort many test results. That’s why the correct description is breaking down blood cells. The other ideas describe preventing clotting or handling platelets, not the destruction of cells. Preventing clotting or reducing clots refers to anticoagulation, while isolating platelets is a separate sample processing step.
