Serum is plasma that has been allowed to clot. It is prepared in the same way as plasma; however, the blood is collected into a tube with no anticoagulant. While spinning in the centrifuge, the clot moves with the cells to the bottom of the blood collection tube, leaving the serum on top.
1. Plasma is the part of the blood that contains both the serum and clotting factors. 2. Serum is the part of the blood that remains once the clotting factors like fibrin have been removed. 3. Plasma contains the clotting factors and water, while serum contains proteins like albumin and globulins.erum is the liquid part of the blood after the coagulation. They contain 6-8% of the proteins that make up blood. They are more or less equally divided between serum albumin and serum globulins. When blood is extracted and left to clot, the clot shrinks after some time.
