Plasma Donation vs Blood Donation

Plasma is a part of Blood. Blood is composed of two main contents: one is solid content called cells, and another is a liquid called Plasma. Plasma is 55% of the blood fluid.

It contains 92% of water in volume. Plasma is detached from the cells for donation.

Blood circulates our body through blood vessels and keeps the heart pumping. Whenever a person has a cut, the blood flows out.

Cells are considered the solid part, while plasma is the liquid component of the blood. Plasma is 55% of total blood volume.

The liquid plasma, after being detached from cells, takes yellow color.

Plasma maintains the blood pressure of the body. It also gets rid of the chemical waste from cells by dissolving and carrying it away.

Even though plasma is detached from the blood cells, it doesn’t lose its proteins, antibodies, and nutrients. In many disorders and deficiencies, the person’s blood thickens, that is, the plasma is lacking.

Therefore they need plasma to live a healthy life. Myasthenia gravis, Guillian Barre syndrome, Wilson’s disease, Hemophilia, etc., are some of the disorders in which patients need plasma.

The process of donating plasma is called Plasmapheresis. The process takes almost one and a half hours.

In this process, the plasma is taken, and the blood cells go back into your body. One person can donate plasma twice a week.

From the four main blood groups, the AB blood group can donate plasma to any other blood group, while others have to be of the same blood group.
