Serum


 
 
Concept Explanation
 

Serum

Serum is the fluid and solute component of blood which does not play a role in clotting. It may be defined as blood plasma without fibrinogens. Serum does not contain white blood cells, red blood  cells, platelets or clotting factors.

 Serum and plasma are obtained from the liquid portion of the blood that is obtained when the cells are removed.Serum is the liquid that remains after the clotting of blood. Whereas, plasma is the liquid that remains when anticoagulant is added to prevent clotting.

Function : 

The human serum is a circulating carrier of exogenous and endogenous liquids in the blood. It allows substances to stick to the molecules within the serum and be buried within it. Human serum thus helps in the transportation of fatty acids and thyroid hormones which act on most of the cells found in the body.

Human serum is used to distribute antibiotics in the body and albumin allows the curable substances in the antibiotics to be bind and carried out throughout the body.

The human off - the - clot serum is the serum that has been allowed to coagulate naturally after collection and has not been exposed to any anticoagulants. This type of serum is ideal for metabolic studies.

Human AB serum is collected from type AB donors and it lacks antibodies against blood type A and B antigens. Human AB serum is used in cell therapy applications and transplantation and tissue engineering.
