What is plasma?

Plasma is the liquid portion of blood and is made up of various blood proteins, including antibodies.

More Info:ย About 50-60% of a personโ€™s blood volume consists of plasma. The other main blood components are red/white blood cells and platelets. All these components combined are referred to as whole blood. Unlike whole blood donation, which can only take place once every 56 days, plasma is quickly replaced by your body.
