What is Plasma?

Plasma is a straw-colored “liquid” portion of the blood, which is also composed of a “cellular” portion consisting of red blood cells, white blood cells, and platelets.

Plasma is made up of:

  • Water (about 90%)
  • Proteins and clotting factors (about 10%)
  • Small amounts of salts, glucose, and lipids

It contains important substances like antibodies that protect us from such diseases as hepatitis, rabies, tetanus, and chicken pox; clotting factors that stop bleeding; and proteins that can be vital to the survival of trauma and burn victims.
