Clotted blood is normally obtained from a specimen of venous blood which has been allowed to clot by standing for 30 minutes. The resulting specimen is usually centrifuged to separate the clotted red blood cells from the serum.

Why do you need to centrifuge to obtain blood plasma but not to obtain blood serum?

To obtain blood plasma, centrifugation is necessary to separate the liquid portion from the cellular components after the blood has been anticoagulated, preventing clotting. Plasma contains clotting factors, which are kept in suspension by the anticoagulant. In contrast, blood serum is obtained after allowing blood to clot, and then centrifuging the clotted sample; the liquid portion that separates is serum, which lacks the clotting factors. Therefore, serum is derived from clotted blood, while plasma requires anticoagulation and centrifugation.
