Detailed explanation-1: -Serum is the liquid that remains after the blood has clotted. Plasma is the liquid that remains when clotting is prevented with the addition of an anticoagulant.
Detailed explanation-2: -A key difference between plasma and serum is that plasma is liquid, and serum is fluid. While most of the components are the same for both plasma and serum, plasma contains fibrinogen which is absent in serum.
Detailed explanation-3: -Serum includes all proteins not used in blood clotting; all electrolytes, antibodies, antigens, hormones; and any exogenous substances (e.g., drugs or microorganisms). Serum does not contain white blood cells (leukocytes), red blood cells (erythrocytes), platelets, or clotting factors.
Detailed explanation-4: -Plasma is the liquid portion of blood; our red and white blood cells and platelets are suspended in plasma as they move throughout our bodies.
