Why serum is preferred over plasma?

In general, serum samples (red top tubes) are preferred for chemistry testing. … For example, LDH, potassium and phosphate are higher in serum than plasma, because of release of these constituents from cells during clotting. Protein and globulins are higher in plasma than serum, because plasma contains fibrinogen.

What is the function of serum?

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.

What is the difference between plasma and serum?

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. … Plasma on the other hand, is mostly used for blood-clotting related problems.

Why is serum important?

Serum is particularly suited to this task because it is made up of smaller molecules that can penetrate deeply into the skin and deliver a very high concentration of active ingredients. This makes them a great tool for targeting specific skincare concerns, like wrinkles. Goodbye, signs of aging!
