What is plasma?

Plasma is the clear liquid portion of blood that exists after both red and white cells are removed.

Plasma makes up approximately 60% of blood, and is composed of 90% water.

Plasma contains proteins and antibodies that are collected for:

  • Immune system deficiencies
  • Rh incompatibility
  • Cardiopulmonary needs
  • Pediatric HIV
  • Burn victims
  • Hepatitis
  • Certain liver conditions
  • Bleeding disorders
  • Shock/trauma victims


We collect your plasma using a process called Plasmapheresis. This is a special process that separates the plasma from the blood and collects it in a bottle. The uncollected parts of the blood, including red blood cells and white blood cells, are returned to the donor. This allows the donor to donate up to two times a week because they do not have to replenish the parts of the blood that are returned to them.
