What Is The Difference Between Plasma & Serum?

Share This Post

Plasma and serum are two elements of the blood that are usually considered the same, but they are very different substances. Here, we will take a look at what plasma and serum are and what are the main differences between them.

Plasma makes up about 50% of the total blood volume. It is the liquid part of blood and 90% is water. Apart from water, plasma also contains fibrinogen (which helps blood to clot normally) and albumin (which stores fluid in the blood and prevents it from entering other tissues).

The purpose of plasma in the blood is to carry all the proteins, hormones, nutrients, antibodies, and so on. As plasma flows through the body, cells store their waste in the plasma, which contributes to another of the plasma's jobs.

What is the contrast between Plasma and Serum?

The distinction between plasma and serum is that plasma is liquid and serum is liquid. While most of the components of plasma and serum are the same, plasma includes fibrinogen, which is not present in serum.

Both plasma and serum can be extracted from the blood using a centrifuge. It should be noted, however, that serum is obtained after blood clotting, whereas plasma can be obtained before blood clotting.

This serum is mainly used for blood groups but also for diagnostic tests. Plasma, on the other hand, is mainly used for blood clotting problems.
