  • Pediatric HIV
  • Burn victims
  • Hepatitis
  • Certain liver conditions
  • Bleeding disorders
  • Shock/trauma victims
what is plasma


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.
