Blood is composed of blood cells and plasma. Centrifugation can use the density difference between blood cells and plasma (or serum) to make them layer under the centrifugal force by high-speed rotation. In this way, the upper-layer serum or plasma can be conveniently obtained for various testing items, such as detecting biochemical indicators like blood glucose, blood lipids, liver and kidney functions. Most of these tests require pure serum or plasma to ensure the accuracy of the results.
