Could Coagulation Occur in Plasma?

Since plasma does not undergo coagulation, it takes less time to collect, and it contains the additional clotting proteins that are not present in serum.

Can serum coagulation occur?

Serum (/ˈsɪərəm/) is the fluid and solute component of blood which does not play a role in clotting. ... Serum does not contain white blood cells (leukocytes), red blood cells (erythrocytes), platelets, or clotting factors.

How does coagulation occur?

Coagulation begins almost instantly after an injury to the endothelium lining a blood vessel. Exposure of blood to the subendothelial space initiates two processes: changes in platelets, and the exposure of subendothelial tissue factor to plasma factor VII, which ultimately leads to cross-linked fibrin formation.
